its absolutely feasible to turn that way, but not very quick. What I am more worried about is what that huge triangle spinning frame does while you wobble across the floor.
About the speed I cant make any predictions since that involves length of leg and the swing angle.
Maybe Ill change the weapon, I have other evil plans
Wouldnt linear actuators be better than co2 pistons?
In what way?
The use of actuators vs pneumatics is always a careful deliberation.
In terms of simplicity, actuators would be better.
However in terms of speed, weight, and oddly enough durability the pneumatic ram would be in an advantage.
Both methods are not wrong. In fact the most famous true walker I know, Mechadon, uses actuators. However in this application I would prefer to use co2 because of speed and weight.

Do you think I could get about 6-8mph?
I should guess so, but there is no way for me to know for sure. Most quadropeds I know are small and they are pretty quick but I cant give you a number on how quick exactly.
How does the weaponry work on robots like Stinger and Weeliwako (RW3, Heat A, it beat Brimhur then lost to Mace II)? It is counted as passive weaponry, but all that happens is the motors stop, so surely the appendage in the middle would just lie there?
hi
since CroOKeD went down quite well i have decided to make 2 more vapours
the 1st
Name:Boxx
Shape: box, lol
number of wheels: 4 go-cart wheels
Drive: 2 wheelchair motors with chain drive to power the other 2 wheels
Armor: 10mm polycarb on the sides, 8mm hardox on the back, a wedge made out of 7mm ti on the front and 7mm ti on the top
Chassis: 10mm hardox
Weight: 98kgs
Ground clearance: 0mm at the front,2mm at the back and 2mm at the sides
Dimensions: 1m long, 0.75m wide and 0.3m high
Weapons: pusher
Top speed: 5mph
batteries: 2 12v sealed-lead-acid wired in series
Weakness: when flipped over it has a high ground clearance at the front
Strength: good pushing power, ivertable
the 2nd
Name: pick-axe of doom
Shape: box wedge
number of wheels: 2 go-cart wheels
Drive: 2 wheelchair motors
Armor: 9mm polycarb for the front/back, 7mm polycarb on the top and 8mm ti on the sides
Chassis: 8mm mild steel
Weapon: 5mm steel tubing(0.6m long) with a 8mm ti axe head(10cm long)powered by a 2kg c02 tank at 750psi with 1 100mm ram
Dimensions: 0.9m long, 0.75m wide and 0.5m high at the back
Top speed: 5mph
Ground clearance: 0mm at the front 2mm at the back and 2mm at the sides
Batteries: 2 12v sealed-lead-acid wired in seires
Weakness: easy to hit with other axes
Strength: can self right with the axe
any comments
jack
I suppose its time I pitched in in this thread:
Name:Boxx
Shape: box, lol
A little vague - try to give an idea of which dimensions are bigger, either a picture or dimensions is whats needed here.
number of wheels: 4 go-cart wheels
Drive: 2 wheelchair motors with chain drive to power the other 2 wheels
So its direct drive but with extra chains to power the secodn wheels? Youd probably be better off with a skid steer system as youd get better controll and the gearing would give you more power.
Armor: 10mm polycarb on the sides, 8mm hardox on the back, a wedge made out of 7mm ti on the front and 7mm ti on the top
Very odd armour distribution there, as a general rule, the back of a robot will need the least armour because hopefully thats not the end that your opponent will be at. Plus 8mm hardox is probably too heavy. If you still want all three hardox on the front, titanium on the sides, polycarb on the back would make more sense.
Chassis: 10mm hardox
Also kind of vague, and if you have chunky hardox as well will be a bit heavy, titanium would probably be better here.
Weight: 98kgs
Ground clearance: 0mm at the front,2mm at the back and 2mm at the sides
Dimensions: 1m long, 0.75m wide and 0.3m high
Weapons: pusher
Id advise at least havign a few static spikes - they really do make rammers more effective. Incidentally those motors are really not up to scratch for a rammer.
Top speed: 5mph
Too slow for a rammer, youll get easily outmanouvered.
batteries: 2 12v sealed-lead-acid wired in series
Ill leave this to someone who can tell you what you DO need, but considering most heavies opperate at 24-48v this isnt enough I dont think, again, particularly for a rammer
.
Weakness: when flipped over it has a high ground clearance at the front
Strength: good pushing power, invertable
You need to mention the invertibleness before this
Hey Jack, this is something ALEX wrote in the Beginners Guide. If you havent already read it, do.
Name:
- Whatever you want it to be, as long as it€™s not offensive and not already taken (either by a real robot or existing vapourbot).
Weight:
- 100kg is the standard, however, other movement mechanisms sometimes get different bonuses. The common ones are: Walkers - 150kg/200kg, Tracks - 110kg, Shufflers: 120kg/150kg. Note that the term shuffler may vary between writers in interpretation, so check.
Shape:
- Whatever you want it to be, just describe it as best you can. A picture usually helps.
Wheels/Motivation:
- Describe in detail wheels, tracks, walking mechanism or anything else you come up with. The more detail you give the better idea the writer will have about what you are imagining, talk about materials, widths, and any special features.
Motors:
- What motors you use and what voltage they run at. Remember they have to be real life components. If you don€™t know what motors to use look in the €˜How Could I Improve€™ Thread, or ask anyone.
Speed:
- Is a pretty obvious one - the faster a machine is the harder to control it will generally be, the slower it is the easier to out manoeuvre. As a guideline, staying between 8mph and 16mph will suit most needs.
Turning circle:
- This will almost always be 0m, however a few robots with more exotic drive systems may vary.
Armour:
- Armour is pretty self explanatory - pick a material and give a thickness for the most basic armour stats, however, you may want to have different materials and/or thicknesses in different parts of the robot. Also if you want to talk about the chassis, that should go here. If you are unsure what material suits your purpose and how much you can fit in, ask someone.
Ground clearance:
- The difference between the bottom of the robots main body and the ground, generally this measures between 3mm and 1cm. If you had no ground clearance you wouldn€™t be able to move, but the higher it is the easier to get under. If you have an axlebot or an externally tracked bot then you done really need to give this stat. Also, €˜skirts€™ should be listed here - essentially pieces of metal that sit against the ground to prevent an opponent getting under so easily - make sure to list what they are made of and how thick they are.
Srimech
- AKA self righting mechanism - essentially how does your robot recover from being flipped over, can it€™s weapon right it or does it have a specific mechanism for doing so.
Weapons:
- Generally the €˜big€™ one, you can use anything you can think of as long as it follows the normal rules (no chemicals, no untethered projectiles etc) Be realistic, generally the more weight you give to a weapon the more powerful you can make it but the more you sacrifice elsewhere in your design. You can have as many weapons as you want, but the more you have the less weight you€™ll be able to use for each and the weaker they€™ll be. However, remember that your own weapon will feed back into your robot - so you better be able to withstand the impact as much as your opponent!
Additionally some writers may ask for strengths/weaknesses and dimensions, but usually these are optional.
