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?

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. This should help with what to put in your stats. For Boxxs motors, I suggest LEM-130s at 36v, or LEM-200s up to 60v, but LEM-200s are heavy so you may need to thin the armour or make it smaller. Like Alex said static spikes or a wedge would help, and for batteries I recommend NiCad battlepacks or A123s

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.

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?

How could I Improve pt 2

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?

2 bosch 750s = 2HP

2 LEM-130s @ 36v= 18HP

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

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

[paulc]

How could I Improve pt 2

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

€ 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.

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

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.

[paulc]

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

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