What reviewers found
Ozobot Evo
- GearBrain (8/10): Teen reviewer found it fun to drive, followed lines and stopped at edges and obstacles; charges in about 15 minutes over USB. Calibration instructions were vague and the case was hard to open. Source
- Galaxus: Took about 55 minutes to fully charge and expected about 30 minutes of play. Rated its game modes and coding app above Sphero Bolt and DJI RoboMaster S1; criticized oversized packaging with little inside. Source
SunFounder PiDog AI Robot Dog Kit
- The Gadgeteer: Took about 4 to 5 hours to build, set up and calibrate over 74 steps; battery charged in about 2 hours and lasted a couple of hours; praised the instructions, 13 preset programs and editable Python, but it is front heavy, sometimes tips over, and is not recommended for kids under 12. Source
- RaspberryTips: Build took about 4 hours with labeled parts and a color manual; walked with good balance, better than the Freenove dog the author tested; calibration after each leg was tedious, the app has fewer actions than Python, and it is not recommended as a first kit. Source
