Designed for ages 10+, RVR+ by Sphero is a drivable robot 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 RVR all over. It 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. RVR’s extremely hackable platform with 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.
