    On the little wheels I've got, Shu! moves at a relatively steady pace as below (5 minutes, 27 seconds into the video):

    Shu! uses a couple of Como 918D motors (https://www.technobotsonline.com/918d15112-1-re-280-1-4mm-metal-geared-motor-15-1.html) which move it quite happily. However, if I was going to build it again,...

    No, I've little engineering experience myself so still learning what things are and what they are used for. Looking at an example, I can see that working though. The flange is threaded to fit onto a...

    Unfortunately not, I had planned to go but then other commitments popped up which I cannot avoid.



    A mistake on my part, I meant on the flange shaft so the nut can seat properly against it....

    I'll drop a M5 bolt through the shaft, possibly grind a small flat onto the motor shaft and then stick a nyloc nut+washer on it if it works.

    Yeah, that was what I suspected I may have to do. I have a pillar drill attachment but not a clamp that fits so I'll see if I can find someone with a facility to this. Thanks ;)

    If the flange was going to sit the way it was in the previous post, I'd possibly agree but the flange is the wrong way around, it needs to be in this orientation, which the holes in the flange...

    Since my last post, I've found that I can drill the flange relatively easily but fouled up on the motor shaft.

    So Kaizen never made it to Grantham, it just wasn't ready in time. The wheels continue to be a problem, I got some M12 plates to mount the wheels to, drilled out the bolt holes to M8 and they are...

    That is a little low but can be compensated for with slightly bigger wheels. The Honey Badger 3 ran both 4S (13.2v nominal) and 6S (19.8v nominal) LiFe batteries at Grantham and both were suitably...

    I would seriously recommend a gearbox (even a simple single stage reduction) to make the machine more drivable - typically planetary gearboxes are used in the FW class. Have a read through the build...

    Drill motors are a good place to start since they come with the gearbox already attached. There are alternatives, such as the Gimson 13.7:1 motors I use in The Honey Badger robots, which are based...

    That is correct, there aren't any max dimensions per se for Beetles or heavier apart from those specified in the FRA rulebook. For reference, my beetleweight (Shu!) is 16.4cm x 32.5cm x 26cm (length...

    So EXR Guildford was a bit of a flat one - It went into the arena and then met Neon. Suffice to say, new wheels and hubs were ordered. :P Took some damage to the wheels and one of the rails but...

    Just wait until it is in the arena. I find myself getting really nervous beforehand and doesn't really pass until about a minute after 3...2...1. ;)

    I am fairly sure there is another new HW at Grantham as well. If I can get Kaizen moving by tomorrow evening, then maybe, just maybe... it definitely won't have a weapon though.

    I can only think of either the chain being out of alignment or a bent tooth on one of the sprockets.

    I didn't get a e-mail about Herne Bay until a couple of days before the event (the Thursday or Friday I think) so I am not too worried just yet.
