How Could I Improve...

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

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

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.

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

MeCANNIBAL

€ WEIGHT: 110kg (Shuffler)

€ ARMOUR: 5MM Titanium on top and bottom.

€ SHAPE: Invertible low cylinder

€ MOTORS: 2 x S28-400 MagMotors at 36V = 12HP

€ LOCOMOTION: 2 x Shuffling pads

€ DIMENSIONS: (L) 80CM (W) 80CM (H) 20CM

€ COLOUR: Black with scary human face with over sized teeth coloured red.

€ WEAPONRY: Ring spinner, made of 8MM Harox, weighing 30KG, powered by 2 x LEM130€™s at 36V to give it spinning speed of 2500RPM and producing 175KJ per blow with a spin-up time of 3.5 seconds. It 2 big teeth made of Hardox that curve out. The teeth are inserted into the body and have rows of Tool Steel spikes on the teeth to dig in. These teeth 5kg each and are designed to send all the spinning energy into one spot rather than small amount into multiple spots. It also has 5 Inches worth of Titanium shock-proof Foam to stop it self-destructing.

€ SPEED: 20MPH

€ GROUND CLEARANCE: 0MM-8MM. It has a full-bodied skirt running completely along the ground that rises when the shell is spinning, but drops when the shell isn€™t spinning. This is powered by a simple 750w Bosch 36V motor and runs at the same time as the spinner.

€ STRENGTH: Scary name and weapon

€ WEAKNESS: Hard to control

Missing batteries...

And youre definitely not going to be able to reach a speed of 20mph with S28-400s on shufflng pads! Lower it to around 10-15mph.

Other than that, a giant improvement.

Nitro-Gene 3.0

More holes? *bashes head against a wall*

May be pushing the weight a bit with this one, but I€™m not sure. Is there such a need for an extreme drive train when you have a very potent weapon? I would personally lower the speed as well. I€™m also unsure about the skirts and give details on batteries if possible. But overall this doesn€™t look that bad€¦

MeCannibal

I don€™t think 2x S28-400€™s do 12hp at 36v, and you€™re wasting battery weight by having them at 36v because you aren€™t going to push anything. The skirt is a nice idea, but I really think you should get rid of it. Cut down the speed a little and you need details of batteries. Other than that, that€™s a seriously good vapourbot.

And I€™ll presume that Dave doesn€™t actually want Shiny Happy People looked at, unless he says otherwise.

Dont bash your head against the wall AJ -itll hurt

Thanks for your very kind comments about my robots and guiding me in the right direction, but there are a few things to explain about my robots.

Nitro-Gene 3.0

Its alright to have holes on this beast as the sides/rear of this are like Tornados rear end, except they come to a fine point, so if a spinner hits it, hes just hitting a line - nothing for him to grip and rip. I know its fast and powerful, but thats an advantage - the speed is spilt over 6 wheels, giving it enough traction to get up to speed almost instantly, and the speed allows me to hit something away, and the power helps me push under things and get them towards the wall and then flip them out.

MeCannibal

I know you want me to get rid of the self-raising skirt, but it gives MeCannibal an advantage over other ring/FB spinners, as it defeats the tactic of someone saying get to it before it spins up - with the self-raising skirt, they HAVE to let it spin before attacking, and then I can unleash my fury! The speeds been lowered though to 10mph to allow for acceleration

And on batteries, I know sod-all about batteries so I cant comment on that.
