RVR is Sphero?s revolutionary take on the programmable robot. It?s drivable right out of the box, packed with a diverse suite of sensors, and built for customization. RVR is a mobile platform for hackers, makers, educators, and learners. Download the Sphero Edu app to drive or program this educational robot anywhere. RVR is equipped with all-terrain treads, a powerful motor, and plenty of torque so you can go faster and farther. Obstacles or uneven surfaces won't affect RVR's ability to drive straight. Thanks to a sophisticated, vector-based control system, RVR goes where you want it to go. Driving RVR is just the beginning. RVR?s extremely hackable platform, featuring a 4-pin UART and an onboard power source, allows you to connect and run third-party hardware like a Raspberry Pi, BBC micro:bit, Arduino or Sphero's own littleBits. Build whatever you want and then take it wherever you want.
