Hello, im looking to build a featherweight robot as a project for uni, but im not too sure where to start. ive been reading up on the forum, to get an idea of parts to look out for. so far, i know ill have to buy a cordless drill and strip it, to get the motor, the gearbox and the battery. battery value should be 12-14.4v. itll be a great help if you guys could give me a push in the correct direction. ive also come across a section in the forum that shows a layout of the drive system, im not too sure if i could use that particular method, or if there are other methods. thank you.
