I can see some mexicans are finally going to know what a 200km/h bitch slap feels like Love the whole overkill on the gears you've used. You actually going to bolt the shell down this time instead of using gravity to keep it attached to the robot??

200KMH ? That's around 5,000 rpm at that diameter . It looks very cool and I hope does well, but mostly I hope it rotates anti-clockwise so we can have a 298 kmh get-together with Jolt

Are those Mini EV's on top? I'm thinking that if everythin else holds together, you should give Queenie what every girl really wants - at set of DeWalts!

After doing a bit of testing over the last couple days I have run into a few problems. First off there was a short circuit between one of the weapon packs and the mini-EVs. A mounting bolt was rubbing against the end cell of the pack and went through the insulation and shorted against the case then through the battery mount which the touched the metal dome (still having clearence problems) then up the hub, into the motor mounts and into the mini-EV. It turns out that the case of a mini-EV is conected to one of terminals (a small tab can be seen through one of the cooling vents) so I fixed that. But the battery connectors had melted in the confusion so I replaced those.
But it turns out that two mini-EVs in parallel running at 14.4V off GP3300s draw enough current themselfs to melt the conectors so I replaced those with those screw terminals. It will make replacing the batteries more time consuming but at least I won't have to resolder my conectors after each time I turn on the weapon.
So I tested it again up at the pub carpark this afternoon (and also gave my new digital video camera a go) and it went well until my weapon isolation link melted.
Here is a video:

Yeah, same issue here. I even tried forcefully downloading it with DAP, but it only downloaded a 1kb file that doesn't even play. Sure you uploaded it

Hmmmm, took 18 months to remove the dome after its last competition. There's quite a bit of rust on a few parts but the bearings and hub are fine. The dome has an ID of 305mm and a wall thickness of 2mm. The internal height is 118mm between the base of the internal hub to the lip of the dome. Now I just need to figure out if I can fit a 300W scooter motor, two cordless drills, 24V of batteries and the electronics into that space. Or if I need to continue asking Gary for a wider dome. Better cranks up inventor. Never tried drawing a doll before.

A few people were asking my brother for drawings/pictures of the hub assembly, which he never posted. Well I've done some for ya.

Old school Prancing Queen setup. I still need the battery and then I'll add some bracing and teeth.

That's really realy impressive ! I don't know all that much about tapered roller bearings, but wouldn't it be better to have the lower roller facing down?

Very cool... I always get a kick out of watching videos of this bot... Good to see some progress!
