How could I Improve pt 2

[kodster]

Its useless though if your opponent lifts all your wheels off the ground. :wink:

And sorry, Aaron, but Ive been toying around with solids for a few hours, and Ive decided that I cant be arsed to go through it all right now (lol, a bit frustrating if you get me) Ill stick with surfacing for now. :P

Will make a final draft of the Troubloon 6 CAD soon.

Liam: Is it possible? Yes, although you would sacrifice a lot of armour for wheels gears and batteries. An active weapon would be out of the question.

So in short you would have a badly turning cardboard box with no weapon. But at least you got 8 wheels.

Right...stats.

Troubloon 6

Shape: Box wedge with inverted rear wedge.

Colour: Mainly brick red. Name on top.

Weight: 100kg

Speed: 12mph

Armour: 3.2mm Hardox monocoque, weighing in at 34kg. The side skirts are 3mm Grade 5 titanium.

Drive: 2 S28-400 MagMotors run at 24 volts.

Power: 8 A123 Li-Ion packs.

Motivation: (I was researching this but then my internet got...bad while I was talking to Aaron :P) 2WD, titanium hubs with a two-component polyurethane coating.

Ground Clearance: 0mm at the front behind the disc, 2cm under the disc, 10mm at the sides (0 with skirts), and 15mm at the rear.

Turning Circle: One that is non-existant

Dimensions in CM: 85 x 65 x 16

Weapon 1: Two 10kg horizontal titanium flywheels, a low one at the front wedge and a high one at the rear wedge, with 2 large Hardox teeth. When flipped, the high rear disc becomes the low front disc and vice-versa. Theyre powered by one S28-400 MagMotor at 36 volts and spin at 2000rpm. They take about 4.7 seconds to get there and dish out approximately 64.3kJ per hit. There is a belt in the weapon drive so that if one of the discs is stalled, the S28 will keep on spinning and the other disc will as well.

Weapon 2: Not really a weapon, but there are extended horns at the front and rear, sharpened and diamond-tipped. The horns at the rear are to spear wedges that try to race in under the rear, and the horns at the front do the same when inverted.

Srimech: Invertible.

Notes: Thanks to Aaron, Leo, and Martijn for all the help in making of this bot, and doubtless there will be more to go.

The CAD is done but I must get some sleep. night.

I guess I should have mentions the method of drawing parts in 2D, then using the planar curves to solid extrusion method

CAD!

Kodys unreliable weight check:

Shocking

Motors = 24kg
Batteries = 14.4kg
Wheels and gearing = ~20kg
Armour (minus front) = ~20kg
Chassis = ~15kg
Front platings = ~5kg - 10kg
Rest = ~10kg
TOTAL = ~108.4kg - 112.4kg

So yeah, its kinda overweight.

Ahem. To help Kody along

Top and bottom plate:

(l x b x h in dm)

per plate: 9 dm x 9 dm x 0.05 dm = 4.05 dm3
So 2 plates: 4.05dm3 x 2 = 8.1 dm3

Ti= 4.5 kg/dm3

8.1 dm3 x 4.5 kg/dm3 = 36.45 kg

Subtract the wheel holes (I dont know the width of the wheels so I went for 10cm wide and 10cm long holes, 16 in total):

16 x (1 dm x 1 dm x 0.05 dm)= 0.8 dm3

0.8 x 4.5 = 3.6 kg

36.45 kg - 3.6 kg = 32.85 kg

And thats just top and bottom, never mind the sides, skirts and shovels.

I think you need to slim down even more than Kody thinks. And some astute readers now also understand that drilling holes to save weight is really nickels and dime work.
