Haynes Manual Build a Robot

[Ocracoke]

OK, so this is how I used to prop the front of Jibril 1.x up on HDPE blocks. I can't claim this to be my idea, it was a fellow MW competitor's idea which we hacked this together at RL Grantham 2019. These are 30mm(?) HDPE blocks with M8 bolts countersunk into the hole to allow the front to slip and slide. Apologies for the duff photo, it was done in a rush.

For Jibril 2.0, I've gone for static castor wheels. The blocks I find work but doesn't permit accuracy in driving very much. These should. They are 50mm wheels from B&Q with a M8 bolt holding them in.

I should really put in a nyloc nut on the end of the bolt as the current one can fall off. You can see these in action in one of the recent "in progress" video's I posted in my build thread. Importantly, in order to spread the weight, you need more than one. I used to have one castor on the 1.x version where 30+kg used to stick it to the floor. Two works better.

Of course, in a FW, that isn't always the case as there simply isn't as much weight. Azriel doesn't have any front castors at all, just slides along on the HDPE forks on the front. You can see how hyper that can be in the recent video I posted as well.

Really helpful thanks I will have a mess around with both wheels and a wedge as planned to recreate what i have made in HDPE once its a working design

I have a few samples from before so might bolt these on for while testing on the MDF base see if that works
