There are plenty of neat projects you can try with a Raspberry Pi. The Freenove Big Hexapod Robot Kit lets you use your Pi to build a walking, self balancing hexapod robot with face recognition, ultrasonic ranging, and live video transmission. You can control the robot wirelessly with your iOS or Android device.
This robot can crawl/turn, walk, and carry up to 1.5kg of load. The kit ships with a Spider Shield for Raspberry Pi, MG996R & MG90S servos, acrylic parts, a HC-SR04 Ultrasonic module, and everything you need to put this robot together.
