Thanks, I lurked around for a month or so before joining, so I knew what to design for...and as for Gabriel, I might stick with the front hinged flipper design now youve said that, just make it more powerful so it can self right.
Would the Mags survive on 30v, or is 24v good enough?
quote:
Ive noticed the dearth of axebots too...
I blame Hardox armour for that.
Another newcomer? This is getting strange, but great at the same time great! Welcome Joey! I havent had a chance to look at your stats yet but at a glance they look almost faultless. Andre, the latest version of Sir Spinalot also looks like a big improvement. Ill review the stats later on as soon as I have time.

I blame Hardox armour for that.Its a major factor for sure. But the possibility of a quick victory with flippers in the form of OOTAs is a major contributor as well.
Hows this?
Gabriel (v1.2)
WEIGHT: 100kgs
DIMENSIONS: 100 x 50 x 35 cm
SHAPE: Elongated triangular pyramid with steep rear and very shallow front
COLOUR: Black with yellow and black chevron tape highlights on the joins and around the weapons.
DRIVE: 2 S28-400 Magmotors driving 2 wheels running off 5 NiCd packs at 30v
SPEED: 14mph average, 20mph max
GROUND CLEARANCE: 0 at front due to spring hinged nose, rising to 7mm at rear
ARMOUR: 3mm aluminium baseplate, 7mm titanium armour on rest of body (7mm hardox in critical areas and edges).
WEAPONS: A high pressure pneumatic front hinged flipper, consisting of the front edge of the body, running from 2 2.5kg CO2 tanks and a hydraulic ram giving 35 flips in a match and capable of flipping 100kgs and lifting several times more than that. Also has hardened steel spikes located on either side of the front point, and it can spin in place to try and do damage with these.
SRIMECH: Via the weapon, which should have enough force to pull it over if it becomes stranded on its back.
NOTES: Components shock mounted for protection vs. spinners and impacts
STRENGTHS: Difficult to get a grip on due to the shape
WEAKNESSES: So-so armour, flipper not really capable of OOTAs}
Joey,
100 x 50 x 35 cm is quite small,specially if you load it with 5kg worth of CO2. The length is ok, but I would make it 75 cm wide and 50 cm high.
Depending on the size of the hydraulic ram you use, OOTAs even with a front hinged flipper are totaly doable. Robots like Envy are very well capable of flipping a robot clean out of the arena without a sweat and that wasnt even a full pressure flipper (it is now i believe but youd have to ask Shane).
2 great examples of hydraulic ram users: Dantomkia, and Bigger Brother.
Thanks for the advice, I was more thinking of the design and how it would be difficult to get someone placed well enough on the flipper to be able to throw them, but I see what you mean...
If I sort out the dimensions, should everything else be okay?
guess so Joey, matter of fact, I think you should try your luck and enter EOTR 4 :proud:
Will do :)
Because the bar is 2000 millerliters and also the bar need to reach to hit the other robots. Really the bar have 2 teeth. I didnt know that. Well Ill reduce it to 2 teeth then
quote:
the bar is 2000 millmeters. 8x8x8 is length times width times height. The bar have 8 teeth on the both sides of the bar. The bar is power by a linear actutaor.
You say the length is 8... 8 is no 2000 if the bar is 2000 long, the dimensions would be 2000*8*8
Ill make 2000 X 8 x 8 then.
please show us the bot as it is now, I have the feeling it would be approved as it is now
2000mm is too long, youd spin the vapourbot instead of the bar.
Time for another bot of my creation, that my incredibly pessimistic self is convinced will be incredibly bad.
The name comes from a game Ive been playing way too much lately.
Name: Sithis
Shape: Circle
Colour: Pure Black
Weight: 100kgs
Dimensions: L:90cm W:90cm, H:30cm
Speed: 15mph
Turning Circle: 0cm
Armour: 8mm Titanium
Ground Clearance: 7mm
Movement: 4 wheels with Vulkanon treads, two on the bottom and two on the top, powered by 2 S28-150 Magmotors running of 2NiCad battlepacks at 24 volts.
Weapons: Full body spinner powered by an etek running at 36volts, which can deal out around 80kjs of power
Scrimech: Invertible.
Let me have a crack at it. :proud:
Shape: Circle
One thing wrong with that shape: its not 3D. :proud: What you mean to say is cylinder, I assume.
Movement: 4 wheels with Vulkanon treads, two on the bottom and two on the top, powered by 2 S28-150 Magmotors running of 2NiCad battlepacks at 24 volts.
I dont think that would work out well. Go for 4 invertible wheels instead of your current set-up , and also go for two LEM130s for motors, and run them at 36 volts, as this will give you a good boost of power. Also, what batteries would you use with those motors?
Weapons: Full body spinner powered by an etek running at 36volts, which can deal out around 80kjs of power
Its not a full-body spinner if its invertible. :proud: The current terminology is ring spinner. Also, youre going to have a hell of a bad time running an Etek at 36 volts. Go for 48v. Also, what teeth is it using? How much does the entire weapon weigh?
Armour: 8mm Titanium
What are you stating this for, the top and bottom, the ring, or everything?
Other than that its quite good. :proud:
Name: Sithis
Shape: Cylinder
Colour: Pure Black
Weight: 100kgs
Dimensions: L:90cm W:90cm, H:30cm
Speed: 15mph
Turning Circle: 0cm
Armour: 8mm Titanium all around.
Ground Clearance: 7mm
Movement: 4 invertable wheels with Vulkanon treads, powered by a couple of LEM130s at 36V with 3NiCad battlepacks
Weapons: Ring spinner powered by an etek running at 48volts, which can deal out around 80kjs of power. Two five kilo hardox teeth, curved to rip armour. The whole ring is about 20kg.
Scrimech: Invertible.
Looks a bit better?
Yes :)
Needs battery stats...
Why would 2 wheels at the bottom and 2 in the air not work? I cant think of a single reason.
Its a little awkward, Id say. I think it would be heavier, too, than a traditional 4WD invertible.
4WD 4 wheels with 2WD invertible. More control, more power.

Sir Spinalot
If you have spare weight, try and use it. First of all I would go for just 2x S28-400 Magmotors for drive, your shape means pushing will be difficult, so save on the motor and battery weight. €œ2000mm 8x8x8€� What kind of dimensions are these? Also I believe 2 metres is over the maximum size rules. €œ3x3x4 with a 7 distance€ also makes little sense to me.
Other stuff to include€¦ Is your armour a monocoque or is it attached to a frame? If so, give details of the frame. How heavy is your spinning bar? What voltage are the weapon motors run at? Do you have any idea of a kinetic output value? What batteries are you using?
This is a big improvement though, so well done. Now I€™ve just noticed Martijn gave basically the same advice. :lame:
Fire and Ice
Your dimensions need to be a bit bigger. Ground clearance at the front of your wedges can be 0mm as well. 10mm Hardox is incredibly heavy, cut it down to 4 or 5mm for the wedges. What voltages are your drive and weapon motors running at?
Nice design though, a few problems to fix and it should be good.
Nidhogg
Again, the dimensions need to be a little bigger. The Leeson motors you are using are probably fine but they are not something I am aware of. Personally I stick to just Magmotors and Lynch Motors, but that€™s up to you. Run the crusher of a Vivoil pump rather than the LEM130. Back up your pressure claims by giving details of the ram used to operate the crusher (eg. Bore and stroke size). I don€™t quite understand the lead screw either.
147
Change the front wedge to 4mm Hardox. As with Nidhogg€™s crusher, give details on the flipper and spike rams. Otherwise, that€™s good.
Gabriel (v1.2)
If you want me to suggest improvements for the other versions, I€™ll do that too. As Leo says, make it a bit bigger. Also, just run the motors at 24v, they are better suited to that. Give some more details for your ram. Again, a good start.
Sithis
Again, I€™ll look at the most recent version. It€™s simple, basic and effective. Lots more detail could be given, I€™ll give some pointers. I€™m guessing you have a frame chassis, so give us some information about it. How fast does your spinner go? That€™s pretty much all I can think of.
I€™m really impressed by the new designs and new competitors coming through. Great work everyone, I€™ve been harsh and picky and I still can€™t find much wrong with many of these vapourbots. :)
Thanks for that, I thought the dimensions were a bit off...I understand most of it, but I have no idea about rams so you might have to suggest a few things for me.
As for the lead screw, I was going on what Panic Attack and Dreadnaut used to use, its not something I fully understand either.
New (updated? repackaged with new sell by date?) stats:

Also has hardened steel spikes located on either side of the front point, and it can spin in place to try and do damage with these.
SRIMECH: Via the weapon, which should have enough force to pull it over if it becomes stranded on its back.
NOTES: Components shock mounted for protection vs. spinners and impacts
STRENGTHS: Difficult to get a grip on due to the shape

Fire And Ice
WEIGHT: 110kgs
DIMENSIONS: 80 x 60 x 25 cm
SHAPE: Invertible box, with a wedge at the front and an inverted wedge at the back.
COLOUR: Flame red and yellow at front, icy blue and green at back.
DRIVE: 4 LEM130 motors running off NiCd packs at 36hp (36v) driving steel-reinforced rubber tracks.
SPEED: 16mph average, 25mph max (rarely used as it is difficult/impossible to turn at this speed)
GROUND CLEARANCE: 10mm at sides, hinged plating extending below both wedges giving zero clearance on whichever side is down (if that makes sense...), 23cm at rear.
ARMOUR: Sides ,front and rear are 6mm hardox, with the top and underside being 4mm titanium.
WEAPONS: Mainly relies on speed and ramming power, but also has two 20cm diameter diamond edged sawblades, one in the centre of each wedge (a la Angel Of Death from S2) powered by S28-150 Magmotors at 24v to around 3500rpm. The saws spin upwards to have some lifting effect as well.
SRIMECH: None, but runs inverted. Has spike strips on the sides to prevent stranding.
NOTES: Armour and components shock mounted to reduce impact from all things large and spinny.
STRENGTHS: Good speed and power, good against spinners
WEAKNESSES: Tracks vulnerable to axes
Nidhogg
WEIGHT: 100kgs
DIMENSIONS: 100 x 70 x 37 (47 inc weapon) cm
SHAPE: Elongated triangular pyramid with steep rear and very shallow front, with a flat bit on the front edge and 2 cutouts in each side panel for eyes
COLOUR: Dark green and brownish roughly chevron patterning, fading to blood red towards the front. Weapons are gold coloured with flame red spines on the arm.
DRIVE: 2 Leeson M1120046 motors run at 24v from 4 NiCd packs driving 2 wheels, with a ball caster just behind the forks in the nose
SPEED: 14mph average, 20mph max
GROUND CLEARANCE: 0 at front due to forks, rising to 10mm at rear
ARMOUR: 4mm Hardox (7mm in key areas) on front, side and rear panels, 3mm aluminium baseplate
WEAPONS: Hydraulic crushing arm (constructed of hardened steel and aluminium alloy) at front driven from a Vivoil pump at 3000psi, giving 9 tonnes of force at the ram and 4.5 tonnes of force at the tip. Also has Haardvark-style lifting forks at the very front run from an S28-150 Magmotor and a lead screw capable of lifting 200kgs, generally used to hold opponents in place for the crusher to do damage.
SRIMECH: Via the weapon, which has decorative spines to assist in self righting. Spikes at the rear prevent the robot getting stranded.
NOTES: Components and armour shock mounted for protection against large scary spinny things. Eyes in side of robot serve as targeting lasers (they dont actually target, they just look really cool)
STRENGTHS: Can cause a lot of damage
WEAKNESSES: Slow at self righting
147
WEIGHT: 100kgs
DIMENSIONS: 105 x 60 x 50 cm
SHAPE: Wedge with flat back
COLOUR: Green on the front (thanks to the felt) with brown wood-effect sides and rear
DRIVE: 2 S28-150 Magmotors running from 4 NiCd packs at 24v driving 2 wheels
SPEED: 15mph average, 20mph max
GROUND CLEARANCE: 0 all around due to a hinged plate on the flipper and side and rear skirts, 10mm underneath
ARMOUR: 4mm Hardox on front, sides and rear (front covered in 2mm green felt, sides and rear covered in 1mm wood-effect fibreglass), 3mm aluminium baseplate and under flipper to deter inquisitive pointy nasty spiky things.
WEAPONS: High pressure pneumatic rear hinged flipper, consisting of the entire front plate of the robot, running from 2 rams and 2 2kg CO2 tanks, giving about 20 flips per fight. Also has a 50cm long steel pneumatic ram at the rear, running from 1 2kg CO2 tank at low pressure, painted to resemble a snooker cue (complete with chalking) which can punch through thin (2mm) titanium but is primarily there to right the robot if it becomes stranded.
SRIMECH: Via weapons. Sides have fibreglass moulding and spikes to prevent stranding.
NOTES: Has several snooker balls (1 cue ball, 4 reds, 1 yellow, 1 blue and 1 black if anyones interested) screwed to the top part of the flipper that not only look good but prevent opponents driving off/over the top. Internal components are shock mounted to reduce damage. Design theme came about as an attempt to differentiate my wedge flipper from everyone elses wedge flipper.
STRENGTHS: Powerful flipper
WEAKNESSES: Flammable (oh yes...), no real damaging weaponry

I see a weakness.
Exposed tires from the top. :proud:
Thanks - Ive also found Kody a weakness - he spells Tyres incorrectly :)
Ive always spelt it tires. :P
Tires is the right spelling... If you mean to describe someone becomming tired. If you want to name the rubber grips slotted onto metal hubs? Ehh, not so much :p

Looks basically sound. Some others might moan about lack of detail such as exact preassure rating but I personally dont mind a lack of exact detail as long as the claims are located somewhere on planet Earth.
Ah, the things you are referring to are known as linear actuators. They are pretty much electrically operated rams. But like you, I know little about them I€™m afraid.
Otherwise, the stats now look pretty much perfect. No doubt someone will point out some more details for the pneumatics and batteries could be given, but as I barely include this myself I can€™t really comment.
Coinst
Not bad at all, very WX 6.0 style. :wink:
Lower the speed a little, add some battery details and it€™s fine.
Namie€™s Style
How low is low pressure? Again, if you have any details on ram sizes, that always helps.
Another almost faultless first attempt at a vapourbot.
Ah. I thought they were different things...never mind, and thanks for the help :)
I really need to edit Sir Spinalot. But Im having a hard time doing that.
How so?
Can someone check this machine out for me.
Name - A Sweet Summers Night On Hammer Hill.
WEIGHT: About 980 Newtons, okay 100 kg mass
SHAPE: It€™s a box, with curved sides to deflect spinners and to prevent resting, with a low wedge at the front
COLOUR: Green
DRIVE: 2 Lem€™s (14 volts) powering 4 Storm 2 style wheels. No idea about batteries
SPEED: Max velocity of about 11 metres per second, but it€™s rare for me to open the taps and allow the beast to full power.
GROUND CLEARANCE: Pretty much zero at the front, and 0mm around the sides with skirts fitted, a nice healthy 15mm without skirts. The skirts can be removed if the battle requires (like coming up against a nasty spinner)
ARMOUR: The Chassis is some box section steel as the base, with some triangular supports where needed, and with some protective foam where needed, the armour itself is some 3.6mm Hardox around the sides and top, where the base-plate is plain old steel. The body shell has quite a few bolts bolting it to the main chassis, where each of the bolts is protected from shearing off due to impacts.
WEAPONS: It€™s an axe, powered by a parvalux PM60M DC motor at 24 volts, which comes with a gearbox, allowing 2 speeds; the axe has interchangeable heads (A nasty spike, an executioner€™s blade or 6 small spikes in a circle to batter other machines). The beauty of having an electric motor is that if the other machine is stuck on the wedge, I can get fast repeated blows in without having to redraw the axe fully.
SRIMECH: At the rear of the machine is a linear actuator powered lifting arm used to self-right the machine.
NOTES: The drive system is designed to give the best feedback and control.
STRENGTHS: Good driver, nasty axe
WEAKNESSES: Can only attack from the front
I presume you mean 24 volts?
Otherwise, in my completely unqualified opinion it looks good, no glaring problems apart from the batteries...I think just saying what type and how many would be enough, maybe 4 NiCd packs or something like that.
A Sweet Summer€™s Night On Hammer Hill
Is the rear also curved as well as the sides? What sort of LEM€™s are you using - 130, 170, 200? Why are you only running them at 14v? To help the writers, use 25mph rather than 11m/s. ~25mph is also a little high for my liking, but that is personal preference. What are your skirts made of? What thickness is the steel you are using? How are you planning on changing the gears for the axe? How long is the axe and what is it made of? Can the linear actuated arm be used as a weapon? Why don€™t you just use the axe to self right you? Why do people still intentionally provide weaknesses in their stats for opponents to exploit?
Nice bot Dave! :rofl:
Didnt notice that, lem 130s at 24 volts
To help the writers, use 25mph rather than 11m/s. ~25mph is also a little high for my liking, but that is personal preference.
I did say it was the max speed, just because a vehicle has a top speed of 100+ mph doesnt mean it has to drive at top speed all the time, its just nice to have a little extra power to escape sticky situations
What are your skirts made of?
I dont know, what do you suggest?
What thickness is the steel you are using?
Does 10mm bars sound alright?
How are you planning on changing the gears for the axe?
By the use of a switch on the controller
How long is the axe and what is it made of?
would you say 50cm is a good length?
And Steel for material. Although Im thinking about having a sword-blade attached to the arm itself.
Can the linear actuated arm be used as a weapon?
Not really,
Why don€™t you just use the axe to self right you?
The axe might get stuck in the floor.
Why do people still intentionally provide weaknesses in their stats for opponents to exploit?
Good point
Joey - Batteries were never my strong point
Batteries are pretty simple:
SLA: Sealed Lead Acid. Usually 12V sometimes 6V. High current output but heavies. For 24V you would need 2 SLAs, 3 for 36V. Most common are 7Ah, 9Ah, 12Ah, 15Ah, and 17Ah. The more Amphours the batteries, the heavier they are and the longer they can produce power. a 7Ah SLA is about 2.7 kg, a 17Ah around 7kg.
Nicad: Nickel Cadmium. 1.2V per cell, most common are 2200mAh and 3000mAh. roughly 85 grams per cell. you would need 20 for 24V, 30 for 36V. They cannot provide as much current in 1 pack as an SLA can, so you will need to put 2 packs side by side at least for Boshes, and for your precious lems and magmotors I would not attempt anything less than 4 packs side by side, or you will blow them up and burn.
Nimh: nickel-metal hydride. Its pretty much the same story as Nicad, but they keep their voltage up longer (also 1.2V per cell) but they cant give as much current as Nicads in one go. They are also lighter, around 65grams per cell. I drive 1 heavy on Nimh and i use for 2 boshes 3 24V packs of 3700mAh. Most used cells are Sanyo 3600mAh, GP3700mAh, GP4300mAh. They have the least internal resistance so they will not heat up as fast as other nimh.
Then there are Lithium based batteries but in fra rules only LiFePo4 will be allowed in heavies in the future.

The issue with that is that you gearing will not be as suited for acceleration or pushing. So you potentially only gain extra speed that you dont plan on gaining, while losing torque/acceleration that youll be using lots of, repeatedly...
quote:
How are you planning on changing the gears for the axe?
By the use of a switch on the controller
Unless that gearbox has some fancy syncro mesh gears and a clutch, good luck with changing gears while powered... If you want to try it, go to your local hardware store, find a two speed drill and try changing gears while drilling....
