Getting ready to mount right foot

OK, so I didn't have a picture of my mounting the drive to the bracket before, so here you can see how it looks on the right foot. It's a little crooked, but it slips on OK, so it's all good:


Of course, I can't attach the drive to the bracket until the bracket & foot shell are all done getting mounted to the ankle bracket, so we'll do that first:

Left foot complete

Once I was satisfied the bracket would work, I went ahead & drilled some holes going through the bracket into the motor drives. I then lock-tited some bolts sticking up through the holes in the drive so I could lower the bracket down onto them and secure them with lock nuts. It came together quite nicely:


(notice also I got the foot hoses attached, yay :)


Here you can see the complete left leg assembly (except the side panel, which I'll attach last) and the right leg, still using the temp wooden bracket. Getting close.

5 months down, 7 to go: and we are MOVING!!!

Went by the hammerspace today to pick up the last prints for the foot--actually the last prints period, I believe--and got into a conversation with the others about the shells. They helped me do some smoothing on the joins, and I did some repairs and things here and there. Going to reinforce the back with some E6000 (I already tacked some braising back there). I think I'm ready to saw open the holes and start working on the actual mountings. Should be pretty soonish. The feet are looking okay:



(Though you can tell this is definitely my first time doing any kind of braising or similar.)

The print jobs were the foot strips and plugs for the braided copper hose. I went by Home Depot but they didn't have any, so I'll have to shop around, alas. Meantime, I can paint and prep as usual.

The big news is we've got a con this weekend. I dunno if I'm going or not, but I might because (drumroll please) R2 is rolling! I figured out the connections and everything, got it all together, and he rolls great--at least on a solid floor. Carpets, not so much. Still, it's pretty exciting.

Dig my main bot's moves:



Oh, and the skins came today--but there was no one to sign for them, so back they went. Yet another delay. Honest to pete.

3 down, 9 to go

So, a quick update: Planet ComiCon went rather well, though I do feel that I have a hell of a long way to go compared to everyone else's stuff. It was so much fun being there, answering questions, explaining how everything worked.

Anyway, looks like the next one is going to be the Maker Faire in June or July, I forget which. I've been thinking about then, and trying to decide what I want to have ready by then. Now, there's no sign of a skin run on the horizon, but I do have the legs more or less, and so I have decided to see if I can have R2 up and rolling around by then. Toward that end, I picked up a Sabertooth 2x32 driver for the motors, slipped in to the latest DDR2 foot driver run after there was a cancellation, and have begun soliciting info from other builders on how to put it all together.

I think probably the Sabertooth will not be going on the motherboard, if only because of the sheer size. Also, there is a heatsink on it, so I will probably mount it to the frame, let the heat dissipate. Still on the fence on 12v vs 24v. When the drives and things arrive, I'll have about 67 pounds of robot tooling around, so 12 should in theory do it, but I suppose in any case we'll see. The system I'm getting is easily adaptable either way.

In the meantime, I'm working on the legs. Got the horseshoes sanded down the other day and have begun to paint. I've got some nice white gloss which should do the trick. Then this weekend I'll see about sanding and painting the legs, possibly even starting to work on attaching the bits together. Come to think of it, need to print up some more ankle cylinders. Get a full set. Hopefully, the drives and things will ship out next week (I got some mounting hardware and a center foot mount as well so they can roll around until I get a foot shell) and I should be rolling along in the not too distant future.
