Back in the day, there was a FEZ Mini Robot which was pretty cool to play with. Is there some such thing these days - maybe something that plugs into a Gadgeteer board?
Ok, that’s interesting. It seems like it balances on 2 wheels. The description talks about adding a WiFi hotspot, camera, etc… I am assuming it won’t balance anything once all this stuff is added? Is there perhaps a 4 wheel version of the same robot?
It actually has 3 wheels. Balancing is an option that you can add (by adding an accelerometer & gyro). There’s no reason you couldn’t also balance with the other components added.
Fast enough to move and to balance. This kit is more or less an introduction to basic robotics. If you are looking for something that has certain specifications, you will more than likely need to add the circuitry yourself.
