Using drill batteries in robots

[john_frizell]

On the underside of your battery pack you should find some screw heads. Undo those screws and the battery case will come apart. You might want to wind some tape around the now exposed batteries just to keep it all in one piece.

i have a question regarding the drill casing, the black bit of casing that has the chuck numbers on, i noticed it can move but can it be taken off without interfering with the gearing and other stuff?

thanks alex

Yep
that is the slip clutch ... a torque relief device that allows the drill to be used as a screwdriver.. the harder its tightened the more power gets transmitted to the screwdriver bit.. until it slips.. preventing the screwdriver bit from tearing up screw heads..

obviously as a drive system for a robot you dont want it to slip at all.. so either have it wound round to the drill setting.. OR
remove it, and lock the slip clutch.

to remove it you need to unscrew the Chuck, the screw unscrews the wrong way.. dont lose the screw !
then unscrew the 2 screws holding the slip clutch plate .. slide it off.. shake out ALL the ball bearings.. then get a 5mm bolt and gently wind it into one of the holes until the driveshaft doesnt slip..

what an appalling description.. Im sure someone else will do better

so this improves performance and reduces the size of the drill?

Hehe, still not finished: http://www.micro-maul.co.uk/howto_drills.htmlhttp://www.micro-maul.co.uk/howto_drills.html

Yup, it will help if you do that aslong as youve got an appropriate way of locking the clutch with screws or through the way that the drill is mounted.

All the best

Ignore the O Ring fix and use the screw method mentioned by Rob.

thanks alex

also i need to change the lay out of the cells, at the moment it is the usual drilll battery arrangment, 3,3,2 and 2 on top. but how do i detach one from another then reattach?

hope this is clear

thanks alex

Its best not to detatch them, But if you have to..

You wont be able to solder ontop of the cells very easily, its not adviseable either, If there are tags on the cells holding them together, cut them in half in the centre, you can solder onto the tags easyer then on the cells themselfs.

I Wouldnt advise it though. But if you have to, try avoiding heating up the cells as much as you can, when you re-join the packs, use a very hot iron and try and get it done quickly.
