Brainlink is a little piece of hardware that can augment (or replace) the brain that’s currently powering your robot. Yes, your robot. Any robot at all, pretty much, as long as it’s controllable with an IR remote or a serial connector or some other common type of interface. Brainlink itself (the plastic triangle thingy in the above pic) talks to your Android phone (or a computer) via Bluetooth, enabling programming and wireless control of whatever it’s attached to.
