'just for fun'.........Luke used to make these just for fun using the meccano motors and bits of meccano spinning round, still hurt if they hit you and bits tended to fly (bits of lego mainly). These often comprised a lego rc drive system and a spinny thing on the front.

If it's for fun then you don't necessarilly need to control the spinner if it is low powered (meccano motors etc) BUT and it's a big BUT, if you start getting to the type of power where it's likely to bruise or draw blood on the spinner or the type of power where the spinner hitting anything can throw the robot more than an inch or two then you should do it properly and follow the rules for your own safety.

In any case you need to protect your eyes. Any bits which can fly can get in your eyes. It takes two seconds to put on a pair of goggles which elimenates about 98% of any risks of messing around with 'toy' spinners.
