If the MiP has piqued your interested in self-balancing robots but you like building things yourself, check out the Two-Wheel Balancing Robot Kit from DFRobot.
The kit includes a custom acrylic case, DFRduino Uno, a six-degrees-of-freedom IMU shield, two DC motors, four analog rotation sensors and a dual motor driver. There’s also plenty of room for creative types to add their extra sensors or boards! Buyers might want to add on an XBee for RC control, or Bluetooth communication using a Bluno board. (Note that this kit does not include a battery.)
The Two-Wheel Balancing Robot Kit can be purchased online for $399.00.
