Post battle analysis and repair

[team death]

Fault diagnosis.......

Last week was the first real event at Robodojo this year with full combat and sportsman events taking

place so I took driller queen and danger UXB with Project fear as a spare.

So Driller Queen was playing up something chronic and there was no visible damage to the Robot-

forwards and backwards was sort of okay but turning left or right was a real struggle.

The problem I discovered after a full strip down at home was very specific to cordless

drill motors left un modified by grub screws/clutch hack.

I leave my drills with the clutch as is but the screws holding the clutch cover in place

had come loose giving the effect of been on a very low torque setting-maybe 4 or 5

compared to setting 13.

In theory this could still happen even if you grub screw the clutch but the screws would

have to come very very loose.

The repair I used was to tighten the screws and melt weld the casing of the drill to the

clutch housing, because of the unique way I fix my wheels on it would not be possible

to fit grub screws as an afterthought.

It sounds like you could do with a couple of new casings for the drill gearbox. What model do you use as i may have a few spares of the outer casings.
