How Could I Improve...

Youre doing a good job Rurak. It took me any weeks to learn much, its taking you much less than that, a few pushes in the right direction will help.

In the mean time, can anyone analyse this, plus think of a better name for me please :lame:

F.P FLIP

€ WEIGHT: 100kg.

€ ARMOUR: 3.25mm Hardox monocoque on the front and 5mm Hardox monocoque for the rest, with 6mm Titanium on the base. Inside, 4cm of Vulkanised Rubber is on the front to protect it from shock-killing

€ SHAPE: A low wedge shape, with corners slanted to make the front more pointed.

€ MOTORS: 2 x LEM130€™s at 36V = 18HP

€ LOCOMOTION: 6 Vulkanised Wheels.

€ DIMENSIONS: (L) 100CM (H) 18CM-16CM (Gets lower) (W) 50CM-35CM (Gets narrower)

€ COLOUR: The body is black, with the name written in black on the silver flipper.

€ WEAPONRY: A C02 powered flipper made from 3.25mm Hardox, and powered a single 1000psi 70mm pneumatic ram, coming from 3 x 1.5kg bottles, giving 50 flips overall. The ram is geared at 4.4:1, so the flipper produces 800kg of force at the tips (can flip 100kg 4ft into the air), and when right underneath, the flipper has 1300kg of force (can flip 100kg 6ft into the air) To help in getting under skirts, a shallow Hardox wedge is added. The flipper can self-right F.P Flip in a 180* flip, but throws itself 1ft backwards and 1.5ft upwards.

€ SPEED: 20mph

€ GROUND CLEARANCE: 8mm all around, except for 0mm at the front, but it also has 6mm Titanium skirts held in place by 4mm Hardox skirts.

€ STRENGTH: Good armour and an awesome weapon.

€ WEAKNESS: Vulnerable to shock-killing from the sides.

Nitro-Gene 6.0 :proud:

What exactly is other peoples understanding of a moncoque? I assumed it meant that the entire robot is made of one fabrication that serves as the armour and the chassis, and this would rule out having different metals.

Im afriad Im not going to call it Nitro-Gene 6.0, and this is a CO2 flipper, not Nitrogen :proud:

And if you can check your forum, ca anyone tell me what they think of the FINAL edition of Nitro, as if 5.0 doesnt work, Ill just stick with 4.0.

By the way Joey, a monocoque is when you build a chassis and then mount the armour and electrics and various bits onto it, thus strengthening the design, so a 5mm Hardox monocoque is stronger than a robot with 5mm Hardox.

Its borderline still, Paul...Id switch it to 7mm titanium armour.

Its still very much overweight - as is the previous version, now I look at it, sorry.

Four LEMs
Hardox armour
Nitrogen flipper

One of these does not belong in a 100kg robot.

Incidentally, Paul, what you described - mounting everything to the chassis - is not what I would refer to as a monocoque, it is what I would refer to as building a robot :proud:. A monocoque would be if you welded the entire bodyshell and support brackets together, installed an access panel, and then mounted everything inside that with no frame.

Okay, not borderline, QUITE overweight. :proud:

Scrap two of the LEMs, Paul. I dont know HOW many times weve tried to tell you that.

Actually Paul, that is exactly what is NOT a monocoque. A monocoque is a shell where the armour is the chassis, therefore saving weight.

quote:

Monocoque (French for single (mono) and shell (coque)) is a construction technique that supports structural load using an objects external skin. This stands in contrast with using an internal framework (or truss) that is then covered with a non-load-bearing skin. Monocoque construction was first widely used in aircraft, starting in the 1930s.
