- Arm jamming due to inadequate pinion support
Victor-Spektrum interface difficulty Current-limiting too restrictive on arm ESC
- Wedges not yet machined or bent
- 0 volt cell in lithium polymer battery pack. Like, zero. Zip. Nada. No recovery.
- Dead arm ESC. That’s why current limiting has been solved. Mysterious non-current cause of failure. Update: Ghettobooster seems to have blown its 5v regulator early (could have been a bad one to start with) and was putting out over 8 volts on the 5v line. I’m surprised the Spektrum and Victors are still alive. Test custom electronics before putting them in the bot, kids.
At this point, it’s almost frivolous to continue. At least the bot moves, and I was able to drive it around for a few minutes.
I have only a few options – drop the lithium pack and go to the MCE 12v NiCd pack, or drop one cell out of the lithium pack and run 11.1v. I’m not sure which one is more effective at this point. I will have to borrow, steal, or beg an arm ESC at the event.
Otherwise, I might as well concentrate on solving the arm jamming issue. There’s a few solutions to that, too.
The final solution (Plan Z!) is to just forget about the arm completely, lock it down, span the front wedge with a durable material, and brick it! That’s right, run as a pushybot.
However, it’s unlikely I’ll activate plan Z. There’s absolutely no point in doing that.
Bot on. I hope the rest of you have better luck.
