Error progression QA #40

Closed pilif0 closed 5 years ago

pilif0 commented 5 years ago

The current single-movement error for moving a piece from A1 to L8 is around 0.5 cm in both dimensions. We could use some analysis of whether that error increases with successive movements. Perhaps moving a piece between A1 and L8 until grabber fails to pick it up, because it is too off centre.

As part of testing #48, I performed 58 moves of a piece between A1 and L8. There was no additive error. The only time it failed (three times) within that test was when the electromagnet turned off while the grabber was going up. I think that was caused by a delay in writing to the electromagnet port driver.
