today on adventures in R2 – broken chain!
I took R2 to the Cure Duchenne event in Dallas this weekend. It started off well enough, but the thick textured carpet may have been extra trouble.
the game room and our dressing room were about as far from each other and the main door as could be – which I think may have wobbled one of the motor brackets loose from the wood internal feet. Also there were a bit more static electricity problems than normal, maybe due to the carpet – but for sure I was resetting R2 a lot more.
anyway when I started driving him back to the dressing area I hear a really loud chunk chunk chunk of the chain slipping, and then noticed that the left drive chain had come off and was on the carpet. I could not find the clip that holds the linking chain link on, so I was stuck pushing him back to the room. All they way across the bowling alley!
at least the right wheels still worked so I only had to push enough to keep him straight.
Luckily the left foot had had a chain problem sometime ago and I replaced it. The spare, I had in my repair kit. so I managed to rethread the spare on and although it was still chunk chunk chunking, I was able to drive him out backwards which did not cause the chain to slip. I think maybe a larger drive gear might help with the slipping. not sure….
anyway when I got home I was able to see that the motor was loose and got it tightened back up. on the other foot I shortened the chain to help with the slipping- i think I may need to do it here too.
