Arduino and Raspberry Pi are wonderful platforms to learn about electronics and coding. Chappi is a 3D printed robot kit powered by Arduino Nano that can be programmed with Arduino IDE. It comes with 3D printed parts, 4 x MG90S servo motors, HC-SR04 ultrasonic sensor, and an IR remote controller.
To program the robot, connect it to a USB port and use Arduino IDE to change the parameters. A turntable kit is also available for it.
