How could I Improve pt 2

Mobile Failure
Shape - Box wedge
Colour - Pale purple
Weight - 100kg
Motors - Those LEM130s running on 36 volts
Wheels - 4 go-kart style wheels
Speed - 16mph
Clearance - the wedge has no clearance, and the sides have 3mm titanium skirts so its 0 there too. Without skirts theres 5mm of clearance
Armour - 6mm titanium and for the bottom its 6mm polycarbonate
Dimensions - 105cm x 75cm x 20cm
Weapons - A titanium axe, using a rack-and-pinion mechanism, powered by 2 2kg CO2 tanks and fed off a 110mm x 20mm pneumatic ram...whew!

Good? Bad?

Hi Tracy,

Two things.

20cm high is very low. specially if you want to put pnuematics in there. make it a little higher please, like 30cm or so.

Either your ram is very wide and very short (4 wide, 0.7 short), or very narrow and still a bit short (0.7 wide and 4 short). Either way not very suitable for an axe. Also at what pressure will you be operating the axe?

As a reference, this is my axe:
120mm bore (wide), 200mm stroke (long), running on CO2 at 16 bar. That gives me 1800kg of force on the ram when it pushes, and 1700kg on the return. That is because there is the rack that slides in and out the ram that takes up space where on the other side there is gas. So one end of the ram is less powerful than the other. On the other hand it fills more quickly since it needs less gas.

Hope this helps.

Thanks Leo. It did indeed help.

Are the edits acceptable? :)

Not bad at all, Tracy. :)

You might want to run the axe at a higher pressure, 1000 PSI would qaudruple the damage

Ben, the axe would explode at that pressure. And CO2 doesnt run at 1000psi anyway.

Colour: Shiny Black
Speed: 22MPH
Weight: 110KG
Armour: 4MM Hardox
Drive: 2 C40-300 Magmotors @ 60V
Power: 6 NiCad Battlepacks @ 60V
Locomotion: 6 Shuffling pads with an Asmaprene/Urethane/Vulkalon coating
Ground clearance: 3MM
Turning Circle: 0
Size: 95X95X25
Weaponry: 2 pairs of horizontal claws, one above the other, one pair moves to the left, one to the right, this should hopefully tears large chunks off opponents
Srimech: A rear-hinged linear actuated bar that reaches from the rear of the robot to the centre point of the robot

I see big problems with that, problems anyone could see. (so Im not biased :P)

Speed: 22MPH
Locomotion: 6 Shuffling pads with an Asmaprene/Urethane/Vulkalon coating

Impossible to control at that speed...

Drive: 2 C40-300 Magmotors @ 60V

I smell burnt motors...C40s cant run at that voltage.

Weaponry: 2 pairs of horizontal claws, one above the other, one pair moves to the left, one to the right, this should hopefully tears large chunks off opponents

Uh...exactly HOW do they move to the left and right. And I still say having two pairs of claws is kinda pointless, and overweight. :P

Deadbeat

Dimensions: 100 X 76 X 27
Drive: 2 X 750 Bosch€™s @ 36v, powered by 5 NiCads
Tyres: 2 X Foam Packed Tyres with Asmaprene Urethane on both
Armour: 4mm Hardox with 4mm Polycarb laminating
Ground Clearence: The front is 0mm, rising to 6mm on the back/sides
Top Speed: 15 mph
Weapon: A nice 19kg eggbeater made of hardox with blunted edges, powered by 2 X LEM-130. This spins at 2700RPM, and reaches that speed in about a second or two. It can flip as well as cause some SERIOUS damage, or even better, knock some bots out using shock treatment.
Srimech: Invertible
Strengths: Deadly Weapon, Decent Pusher, Heavily shock-proofed
Weaknesses: Wheels may be exposed to crushers but nonetheless very sturdy
