Spider Robot • ETR-01

The Spider Robot is a six-legged walking robot which is driven with 18 servo motors. These 18 servo motors are controlled by PWM signals generated from the Altera DE0-Nano-SoC board embedded inside the Spider. The Spider itself can be remotely controlled by a Bluetooth enabled Android device. The software app that we developed can control the Spider to move in four directions, swing based on the g-sensor data, and even complete a dance with pre-defined movements.

Description

All the source codes of the Spider Robot is available with the kit. You can modify the code to improve or to change the Spider’s functions according to specific applications. The source codes include Android project, Linux application project, and a Quartus project.

Note that there is a 2×20 GPIO expansion header available on the DE0-Nano-SoC board. You are free to use it to expand functions, such as camera, ultrasonic, or anything else
