How could I Improve pt 2

D.V.D: THE THRID (Death Via Drum)

€ WEIGHT: 100kg

€ ARMOUR: 5mm Hardox body and 7mm Titanium wedges.

€ SHAPE: An invertible parallelogram shape ( /===/) with triangular sides and rear, slanted like this and the rear like this: . The wedges are hindged at 30*, making it very easy to get under anything.

€ MOTORS: 2 x LEM130€™s at 36V = 18HP

€ LOCOMOTION: 4 Vulcanised Wheels with Aluminium 2 spoke hubs.

€ DIMENSIONS: (L) 90CM (H) 20CM (W) 90CM

€ COLOUR: White for the drums, black for the body and teeth of the drums..

€ WEAPONRY: 2 x 15kg Titanium drums with bluntened Hardox teeth, one in the front wedge, the second in the rear wedge. Both the drums are connected by a chain-and-gear mechanism, so when the front one spins, so does the rear, and they spin upwards. Both drums are powered by 2 x LEM130s at 36V, allowing a maximum speed of 3600rpm. Both drums have an output of 32.5kj each, and the wedges on the front and rear have an extension plate, allowing them to get under the opposing robot, and drum the bottoms. The power also means that I can pudh other around the ring as well. 1 Inch of PU Foam in the front and back mean that the robot wont shock-kill itself, or get shock-killed. The insides are also strapped and bolted down with Tool Steel bolts.

€ SPEED: 20mph

€ GROUND CLEARANCE: The front and rear clearance is absolute 0mm. 6mm on the sides and rear.

€ STRENGTH: Strong drums.

€ WEAKNESS: Unksirted side clearance.

Whats wrong with this?

ok thanks alex

forget chain drive, ill go for skid steering

would 2 bosch750s be better than the wheelchair motors

ill make the chassis out of 8mm titanium

i will also add 2 spikes made out of 5mm mild steel on the back

the new back plate is 5.5mm titanium

hows that?

jack

2 bosch 750s = 2HP

2 LEM-130s @ 36v= 18HP

2 LEM-200s @ 48v/60v = 50HP

2 B42-500s @ 48v/60v= 60HP

:proud:

Given youre making a rammer, Id use LEM130s at 36V, as they weigh only 1kg more than a Bosch, but they have 9 times more power per motor.

D.V.D: THE THRID (Death Via Drum)

I presume you mean the Third :proud:

€ WEIGHT: 100kg

€ ARMOUR: 5mm Hardox body and 7mm Titanium wedges.

Way too thick, though you may get away with 7mm titanium all over, which successful vapours like FOTW and BTRIII do.

€ SHAPE: An invertible parallelogram shape ( /===/) with triangular sides and rear, slanted like this and the rear like this: . The wedges are hindged at 30*, making it very easy to get under anything.

I dont understand how it can have an angled rear and be a paralellogram

€ MOTORS: 2 x LEM130€™s at 36V = 18HP

Youll have to change either these or the weapon motors, or both

€ LOCOMOTION: 4 Vulcanised Wheels with Aluminium 2 spoke hubs.

€ DIMENSIONS: (L) 90CM (H) 20CM (W) 90CM

With 5mm hardox at those dimensions your gonna be overweight

€ COLOUR: White for the drums, black for the body and teeth of the drums..

€ WEAPONRY: 2 x 15kg Titanium drums with bluntened Hardox teeth, one in the front wedge, the second in the rear wedge. Both the drums are connected by a chain-and-gear mechanism, so when the front one spins, so does the rear, and they spin upwards. Both drums are powered by 2 x LEM130s at 36V, allowing a maximum speed of 3600rpm.

The power also means that I can pudh other around the ring as well. 1 Inch of PU Foam in the front and back mean that the robot wont shock-kill itself, or get shock-killed. The insides are also strapped and bolted down with Tool Steel bolts.

See motors.

€ SPEED: 20mph

€ GROUND CLEARANCE: The front and rear clearance is absolute 0mm. 6mm on the sides and rear.

With 0 at front and rear it wont move much

There are people (Leo,Kody etc.) who will be able to help more than me though

Hows this?

Paul,

8 * 8 * 0.14 * 4.5= 40.32 kg for the top and bottom plate.

The sides, without the angle is 8 * 2 * 0.14 * 4.5 = 10.08 kg, but that will be more because of the angles.

So on armour alone you are already on 50kg.

That, coupled with 4 wheels, 4 motors, all the mounts, gears, chains, and batteries, I dont see how this could be below 100kg if 30kg of it is already for the drums.

Thin the armour down to 5mm Titanium for the body.

Thin it down yourself Paul, you got the calculation in front of you.

hi

for boxxs motors i will use 2 lem130s

and for batteries i will use a123s

jack

Jack, can you place your stats of Boxx again with all the changes please? It is getting confusing for us if you only post the changes. I think it is best if we focus on Boxx first and on Pic-Axe after we smooth Boxx out.

ok Leo
Name:Boxx
Shape:box
Dimensions:1m(L)0.6m(W)and 0.3m(H)
Number of wheels:4
Make of wheels:go-cart wheels
Drive:2 lem130s
Batteries:a123
Chassis:8mm titanium
Armor:7mm titanium wedge on the front, 5.5mm titanium on the back,10mm polycarb on the sides and 7mm titanium on the top
Weight:98kgs
Ground clearance:0mm on the front,2mm at the back+sides
Top speed:11mph
Strength:fast,good pushing power, invertable
Weakness:when flipped over it has a high ground clearance at the front

hows that???

jack

Name:Boxx
Shape:box
Dimensions:1m(L)0.6m(W)and 0.3m(H)

Might do with being slightly wider, are you going for a tornado like scale?

Number of wheels:4
Make of wheels:go-cart wheels

This doesnt need to be two separate stats, just have Wheels: 4 x Go kart wheels

Drive:2 lem130s

At what voltage?

Batteries:a123

Youll want a quantity.
Chassis:8mm titanium
Armor:7mm titanium wedge on the front, 5.5mm titanium on the back,10mm polycarb on the sides and 7mm titanium on the top
Weight:98kgs
Ground clearance:0mm on the front,2mm at the back+sides
Top speed:11mph
Strength:fast,good pushing power, invertable
Weakness:when flipped over it has a high ground clearance at the front

You also dont have any weapons at all now, of course this is your choice and you dont have to, but even some small spikes will cause minor scatches which could tip a close judges decision in your favour.

Jack, if you have a wedge at the front say in the shape:
Box wedge/Box with a wedge at the front

LEM-130s would work well at 36v and give you 18HP, also you could go a lot faster than 11mph with them

hi
1.yes i am looking to be about tornado size
2.the motors will be at 36v
3.i will have 3 a123s
4.i will also have a spike made out of 5mm mild steel either side of the wedge
jack

I agree with what Alex and Liam have said. I also would like to add:

36V on A123 is tricky since A123 cells do not work in increments of 12V as the other cells do (1 cell of A123 is 3.3V). The closest you get is 36.3V (11 cells). 6 packs of 11 cells weigh about 5kg including everything. That will be plenty for your robot.

10 mm polycarb is very weak for the sides. It is very lightweight, but vapourbot spinners punch through that like a fist through a sheet of wet newspaper.

I would suggest to make the whole robot Ti, so top, bottom, back, the lot. What thickness I leave up to you.

Ive redone my original crusher robot, is it OK?

Robot Name: Sergeant Slaughter
Shape: An elongated pyramid with a very shallow front (like Gabriel II:proud: ) and a wedged rear that is angled at 42*
Weight: 100kg
Length: 90cm
Width: 85cm
Height: 20cm
Motivation: 2 x aluminium wheels with vulcanised foam-filled tyres, internally mounted at the rear. It also has a ball castor in the middle of the front point to aid mobility
Drive: 2 x S28-400 magmotors powered by 2 x NiCad battlepacks
Armour: 3.25mm hardox all over the top, 4mm aluminium on the base
Weaponry: A 2D Razer-style crushing beak made of titanium/vanadium alloy with a serrated underside. It is drilled with speed holes and actuated by an M-Mac M40 hydraulic actuator at 2500psi and 12v, this provides 14 tonnes of crushing force
Speed: 15mph
Ground Clearance: 0 at the front, 8mm at sides and rear
Turning Circle: 0
Srimech: On the sides of the crusher there are two Razer-style wings that operate via steel cables joined to the crusher, should right the robot in about 1.5 seconds
Colour: Gold with a red crusher and sapphire self-righting wings
Strengths: Powerful weapon
Weaknesses: Comparatively slow self-righting, ground clearance

Not quite thaty easily Leo, besides, you dont get explosions of sharp shards from a wet newspaper lol.

Anyway, Jack: Your armour distribution is still rather odd. Remember, the top is probably where you need least armour, because you only have to worry about axes and crushers really. The back is second least, front is most and sides second most.

Id personally go with something like...
Front: 7mm titanium
Top: 30mm polycarb
Back/sides: 5mm titaniumm

Can I also add suggest, mention the wedge in the shape too because itll get missed where it is.

For the spikes you probably want just a solid spike of whatever material, unless you mean a rolled spike? (eg like rolling up a sheet of paper into a spike, but with metal?)

Good luck with that, AJ will be beheading you before you know it. :lame:

The M40 cannot supply 14 tonnes of force on 2500PSI anyway. the bore of that ram is 40mm so at 172Bar (2500psi) gives 21893.30214 Newtons of force. Thats about 2234 kg or 2.23 Tonnes of force. To achieve 14 tonnes of force on a 40mm bore ram you would need 16170 PSI of pressure.

A couple of questions:

What do you mean with a 2D Razer-style crushing beak? As in flat?
What powers the pump?

What I mean by 2D is kind of like Tiberius (do you know what I mean?).

As for what powers the pump, I dont know what you mean :proud:

I wouldnt exactly call the beak of Tiberius 2D. What would be 3D then?

Last time I checked Vivoil or any other pump for that matter need a motor to work them, unless you have very well trained squirrels. :)

In any case, 2 battery packs would not be sufficient to run 2 S28-400s and the motor for the pump.

3D would be Razer, so I guess it would be better just to say the crusher has very thin?

Good luck running a M40 on 12 volts

Here we go...

Our arena is the Robot Wars series 7 arena
Our house robots are Cassius Chrome and Shunt

3-2-1 Activate

cROokED charges at Hector, and starts pushing him towards the wall, Hector activates his claws and makes some nice big holes in cROokED, who now fires his flipper and Hector goes over the top of cROokED and is now dragging him towards the Drop Zone
Crash!!!
Ouch, that has got to hurt, that was a 50KG Fridge, but only small dents are visable on cROokED, who is now being pushed towards Shunt
Smash! Crash! Crunch!
multiple hits from Shunt there, wait.. is that smoke, IT IS SMOKE!!, cROokED is on fire!, and there appears to be a small red box on the floor, ITS A BATTERY!, Hector now backs off and comes in again, but cROokED has fired his flipper, BUT TOO EARLY!, Hector is closing the jaws
Bang!
The ram has exploded, cROokED is weaponless!, Hector now pushing the lifeless corpse of cROokED, towards the pit, it on the pit, and Hector pushes the pit button, its all over, bye bye cROokED
Cease!

cROokED needs staightening
Hector is the winner!

Could use more detail, but otherwise good. :)

:sad:
back to the workshop for me.

I dont like the use of arena hazards such as the drop zone, also how did the battery magically appear outside the robot, and surely if the battery was out and the robot on fire, how could the flipper work?

(Not to mention the exploding ram)

the claws of Hector grabbed the battery and pulled it out, and the fire was at the back of the robot
