Is it approved?

So what actually are the stats now?

I am confused right now to the point of even forgetting about offering help anymore, if this is how its going to turn out...

For the srimech, I would go for a simple electric linear actuator.

I wouldnt call it having a lack of traction as a weakness

Sir Spinalot = Overweight.

Your building a clone of Tornado Mer basically, so you might as well copy half the stats. Go 4 x S28-400 magmotors, this is on par with an ETEK, but it will all fit within 100mm tall. Drives, another pair of S28s will suffice here. Stack up on at least 8 x 24v 3600mAH battery packs.. Bring the size down to 800mm x 800mm x 120mm. Make the bar 1200+mm to get enough reach when attacking. Make the whole body out of 5mm titanium. Should be close to the weight limit. And a lot more realistic compared to you currently design.

Square = Overweight

4 x LEM130s for drive, plus a heavy hydraulic system that youve provided no real information for, where is your evidence that it has 9tonne at the tip? No information on batteries either.

I seem to be repeating myself here, but if you cannot back up your claims with some maths or information, dont make those claims. :wink:

Ive already explained that I know nothing about batteries, so I cannot say anything about them. As for the weapon and drive, reduce the drive to 2 x LEM130s at 36V. About the weapon, its based uses the Razer mechanism to power the claws. Except that the Razer system runs on a reverse ratio - so it 3:6:9 the further in you go. With me its 9:6:3, as Im doing it in reverse.

SO LEARN ABOUT THEM!

Andre, could you please post the most recent version of Sir Spinalots stats? There are so many different versions and corrections that I dont know where we are at any more.

Paul, other than the motors which you have now fixed, its not bad. A few more details are required though. Personally, I dont understand batteries either, but that doesnt mean I leave them out of my stats. The majority of vapourbots here use the 2x LEM130 @ 36v set-up, so all you have to do is look around and see what other people are using.

Also, saying it uses the Razer mechanism is too vague. You have two horizontal claws, correct? Razer has one vertical claw, correct? So you need to explain how the system is adapted to fit Square. Again, you also need to back up this claim of 9 tonnes of force. For example, state the size of the ram(s) you are using, and the pressure that they run at. In fact, at the moment, I am presuming that this system is hydraulic, but you havent said this in the stats.

Using the Razer system is fine, but what if the writer has never seen Razer? You need to find out what it used, and put these in your stats. To help you on your way, use http://www.pneumaticsonline.com/Calc5.asp

Well, Ive finally decided to add batteries to my stats (something whuch I actually HAVENT done before because I was so unsure about my own knowledge on them). And Ive also decided not to make Square a crusher, but a double axer. Have a look as the stats for more details.

SQUARE

€ WEIGHT: 100kg

€ ARMOUR: The top armour is 4mm Titanium. The sides (all - front back AND sides) are 5mm Hardox. At the front, between the claws, is 5cm of Vulkanised Rubber to put off spinner blows.

€ SHAPE: Low invertible box with slightly curved sides to prevent balancing on the sides.

€ MOTORS: 2 x LEM 130€™s at 36V = 18HP (90x 3000mAh NiCad€™s producing 36V make up the batteries)

€ LOCOMOTION: 4 Vulkanised Wheels.

€ DIMENSIONS: (L) 70CM (H) 25CM (W) 70CM

€ COLOUR: Painted red for the claws and front, back and sides, and white for the top and bottom (the name is drawn on the top in black).

€ WEAPONRY: Two side-mounted axes made of G5 Titanium with 2 x Hardox spikes, 30mm in diameter which come to a sharp, fine point. The axes are powered by 2 x 140mm rams at 200psi Nitrogen. The axes, given this means of power and movement, can give off 4 tons of force on each axe - it should destroy Aluminium and Titanium and cause quite a bit of harm to Hardox.

€ SPEED: 20mph

€ GROUND CLEARANCE: 0-5MM. On all sides are fixed skirts, made of 4mm Titanium.

€ STRENGTH: Pushing Power.

€ WEAKNESS: Unprotected side clearance.

Destroy titanium?

So basically square is like Kan-Opener, but with 4 wheels.

Paul, the force of your rams are 2 tons each, not 4 (140 mm @ 200psi). Also keep in mind these are only near the ram, the tips will be far less force because of the leveradge.

The specs themselves are not unrealistic, although I would prefer CO2 over Nitrogen. And if your robot can drive on 2 sides, there is no need for skirts. most of the time they just get in the way of driving and a flipper can always get you anyway with those claws sticking out.

Correct me if Im wrong, but 200psi is a pretty small amount of gas pressure, there is no way that is going to produce 4 tons of axe pressure with an axe full stop let alone this setup.

Beside axes depending on whether you are using them to bludgeon or pierce never really destroy anything. If you have a sharp tip (like dominator, mortis or killerhurtz) it will puncture it or if you have a broad edge (like terrorhurtz) then it will buckle the armour. As for harming hardox - not especially likely with an axe.

Bear in mind that horizontal axes are also always weaker than vertical ones: for one whey will knock an opponent back rather than damagign them because the opponent isnt trapped between an imovable object (ie the floor) and secondly because it doesnt have gravity ot offer a little help.

Alex, a 140mm ram with 13.7 bars of pressure is noting to sneeze at either. they would work great for clamping, with close to a tonne at each tip.
