And of course with just a few days to go, we’ve had a major disaster on the robot. This tiny gear has cracked:
And so it won’t stay on the shaft. Sadly, its the main pinion gear of one of our motors, so we’re down a motor and we don’t have a spare. 🙁
We quickly ordered another from China (but that won’t arrive before PiWars). We also ordered some similar looking gear motors from Ireland – hopefully that will turn up in time, and the gearboxes will be similar enough that we can either transplant the entire ‘box or just steal the pinion gear from them. *crosses fingers*
Or we’ll have to go to PiWars with a lame robot 🙁
That’s a real mare at this stage of the game – did you manage to sort?
If you ordered from eBay, I’m fairly certain I know which seller!
If you’re totally stuck, let me know size / spec / rpm and I may have a spare I can give you.
DP.
David – it would be wonderful if you have one – thank you.
We’ve patched it with a different motor, but it isn’t quite the same – no encoder and slightly different gear ratio.
This is the motor we’re using:
