The Raspberry Pi is a wonderful platform for learning electronics and coding. Thanks to the SunFounder PiCrawler, you can build a robot powered by RPi. This robot kit is compatible with Raspberry Pi 4B, 3B, 3B+ and 2B. It comes with a pan-tilt camera and an ultrasonic module for obstacle avoidance, object/face recognition, and other functions.
The PiCrawler is ready for Python programming but it also supports a visual programming interface (Ezblock). The robot comes with 13 preprogrammed actions to get you started (push up, twist & wave, …). The PiCrawler has a metal structure with 12 semi-metal servos for smooth movement. You can control it with your PC or mobile device.[where to get it]
