Built by folding and snapping together flat sheets of plastic, Kamigami robots feature a bevy of sensors (3-axis accelerometer, gyroscope, etc.) and are programmed using a tablet or smartphone. Kamigami debuted bug-like robots last year, but really nailed it this year with a Jurassic World inspired Velociraptor. Building the dino is a blast and provides parents with an excuse to do their best John Hammond impersonation.
