Sphero RVR Programmable Robot
Prior Sphero products have asked what you could do with them. The RVR asks what you can build with it. Designed with makers and students in mind, it's drivable out of the box, with all-terrain treads, a powerful, extremely accurate drivetrain, a high-capacity, USB-C rechargeable battery, and sensors for detecting ambient light, colors, direction, articulation, and more. It's programmable via the Sphero EDU app, or for more advanced operations, it can interface with a Raspberry Pi, Arduino, micro:bit, and tons of other attachments via the 4-pin UART and onboard USB ports, making it a capable platform for all sorts of projects.
