How Could I Improve...

Ok, can someone check this out, see if its not too terrible:

SHAPE: Box with wedge at front and inverted wedge at back.
COLOUR: Deep blue.
WEIGHT: Around 100kg
DIMENSIONS: L:110cm W:65cm H:23cm
SPEED: 25mph
TURNING CIRCLE:0mm

Id thin down the armour to 4 or 5 mm hardox, and it should be fine. Or maybe make the top and bottom armour 3.5 mm hardox so youve got more weight allowance for the front, sides, etc which is where spinners are most likely to attack.

I think you can go a lot faster than 25mph. Not that that would be of any use in a small arena.

He may just want to keep that as his average speed...but whoa, 4 LEM130s @ 48v? Crazy. However, Danny, Id add some more NiCads so that your vapour doesnt run out of power after a minute.

Also, how can its rear ground clearance be 25cm when it isnt even that high? Care to explain?

What do you lot reckon?

Ha-ka (Just going back to the original name)

Weight - 95.9kg
Dimensions - 75cm x 75cm x 45cm
Speed - 11.7mph 5.2m/s
Turning Circle - 0
Shape - Truncated pyramid with skirts all round.
Drive - 4 x S28-150 Magmotors producing just under 12BHp
Wheels - 4 lightweight thin aluminium hubs with tyres made from an old conveyor belt with tread cut into it.
Ground Clearance - 0mm under skirts, main body 6mm
Armour - 7mm Hardox, with 3.25mm Hardox skirts.
Weapon - A double ended Excalibur style axe made of hardened titanium. The axe weighs around about 10kg and is powered by 2 rams running off 750psi CO2. We doubt it will do much to Hardox unless it focuses on the same spot, however it should treat all but the thickest titanium with disregard.
Srimech - There are 2 long spikes on the side of the axe, which should allow us to gain purchase against the floor when flipped and right ourselves. These are made from 1cm titanium in order for them not to be too susceptible to breaking.
Strengths - Built to be robust, shouldn€™t be destroyed, and will destroy fodder.
Weaknesses - Relatively low drive. Weapon may not be effective against tougher armoured robots

Weight Breakdown (All parts are based on educated guesses)

Chassis - 10kg
Armour - 44kg
Drive - 6.9kg
Wheels - 6kg
Weapon - 10kg
Weapon Power - 9kg
Various other bits - 10kg

Thin the hardox down to 5mm

You can save a bit more weight by making the skirts out of Ti instead of hardox. Anything powerful enough to damage the skirts will also be powerful enough to break whatevers holding the skirt in place, so hardox isnt really a wonderful material.

I just wanted to ask people about this robot and tell me whats right/wrong with it.

UP-THRUST

€ WEIGHT: 100kg

€ ARMOUR: 10MM ABC (Aluminium Boron Carbide) for the body. 4MM Hardox for the flipper with a

€ SHAPE: High wedge shape with sides and rear sloped at 42* to stop spinners. At the rear is a extra Hardox wedge to prevent self-flipping

€ MOTORS: 2 x LEM 130€™s at 36V = 18HP

€ LOCOMOTION: 6 x Vulkanised wheels

€ DIMENSIONS: (L) 80CM (H) 35CM (W) 80CM

€ COLOUR: The colour for the body is black with a red sign on the flipper saying €˜goodbye to the ground€™

€ WEAPONRY: The weaponry is a Nitrogen powered flipper, powered by a single 80mm ram at 1000psi, running on a 1:1 ratio, so the maximum it can flip is 3500kg! The Nitrogen is contained in 3 x 2kg bottles, giving me 22 flips.The flipper has a steel extension plate.

€ GROUND CLEARANCE: 0-7MM. 0 at the front and 7mm on the sides, without the 10mm Titanium skirts.

€ STRENGTH: Hellish flipper.

€ WEAKNESS: Weak body armour.

Cut the armour down to around 5mm Hardox. Do what Kody said regarding the clearance and motors/batteries. Otherwise that€™s pretty good.

Ha-ka

What batteries are you using? You€™re running at 24v to get 12hp, correct? Cut the Hardox down slightly to 4mm or 5mm. Too be picky, what length is the axe? What size rams are you using? How much gas is on board? Overall it€™s a very good bot.

Up Thrust

4mm Hardox for the flipper with a€¦ what? 10mm Ti skirting is way too thick, halve it at least. What batteries are you using? Turning circle? What hinge is the flipper? It€™s a nice GeForce clone, but there is one serious problem with the flipper. GeForce has the mechanism to reduce its flipping power so that it doesn€™t destroy itself. 1500kgs of force is already overkill, and you are saying that you want to put 3500kgs through the flipper?

But well done for cloning the master of clones!

IMO, Aluminum Boron Carbide is over-rated for armour.

Besides some writers have no idea what it will act like in a fight, as its rare (and expensive) stuff.

Well his robot is 23cm high, plus the 20mm (2cm) clearance provided by the wheels = 25cm at the tip of the inverted wedge.

[kodster]

Just because I wasnt studying the stats that analytically at the moment...

And besides, why does he need to put that anyway if its an inverted wedge? Well pretty much know what the clearance is.

[tacoman]

I was just being thorough.

Your right, it is pretty unnecessary.

Funny, I just said the same about Titanium this morning.

Paul, the trick with flippers is this:

You have an amount of force that comes out of your cilinder. With the flipperarm you make a decision to use that force for either speed of power. It is always a trade-off.

Place the cilinder near the front you will have a lot of power, but gives your arm a limited amount of travel and swing and therefore you will more likely topple a robot over than really give it a launch.

Place the cilinder at the back gives you a lot of momentum but not a lot of power on the tip of the arm.

The trick is to find the sweet spot, where travel of the arm, speed, and sufficient power on the tip are at its optimum.

On our flippers we usualy have a 3:1 ratio, where 3500 kg of force at the ram still gives you a very impressive 1167kg (rounded of) at the tip of the arm. If your opponents are only 100kg, that is still plenty to send them flying.

Furthermore, Nitrogen has a serious downside, every flip you make the pressure drops, the flipping is not a constant. Your second flip will be less than the 1st, the 3d less than the 2nd and so on.

NITRO-GENE 3.0

€ WEIGHT: 100kg

€ ARMOUR: 4mm Hardox for the body. Holes are drilled into the slanted sides to allow for a 7mm Hardox flipper

€ SHAPE: Low invertible box with pointed sides and rear. At the front is a Storm 2 style wedge to end in getting underneath other robots.

€ MOTORS: 4 x LEM 130€™s at 36V = 36HP

€ LOCOMOTION: 6 Vulkanised Wheels.

€ DIMENSIONS: (L) 80CM (H) 15CM (W) 60CM

€ COLOUR: Black all over with the flipper coloured red.

€ WEAPONRY: A full pressure Nitrogen powered flipper at 1000psi, using a single 80mm ram at 1000psi. The flipper is mounted in the middle of the robot, and is 20cm wide and runs 30cm up the body. Using a 3cm long Titanium strip underneath the flipper, and a heavy flipping arm, the flipper runs completely along the ground. Running on a ratio 2.5:1, the flipper produces 2000kg of force at the tips, allowing me to launch anyone away! This version has 3 x 3kg Nitrogen bottles, giving me 30 flips!

€ SPEED: 25mph

€ GROUND CLEARANCE: 0MM-2CM. At the front, it is completely 0mm. On the sides/rear, its 2cm. The orginal weakness of Nitro-Gene (its high ground clearance) has been seen to by the skirts on the sides/rear. They are 4mm Hardox skirts and are joined together like BioHazard. To avoid them breaking off, they are held in place by Hardox hinges.

€ STRENGTH: Pushing power and weaponry.

€ WEAKNESS: High speed may mean difficult driving

Would you like to give me advice on this new version of Nitro-Gene, and tell me if they may be any troubles.
