There is no better way to learn electronics and robotics than playing around with Raspberry Pi, Arduino, and other comparable platforms. The Critter is a 3D printed Arduino robot kit designed to help you get started in coding and 3D printing. The robot uses its two front legs to drag itself.
The custom PCB inside allows you to take advantage of WiFi, Bluetooth, and sensors to program the robot. The Critter can be operated with an Android app. It can be programmed using a graphical programming interface.
