The Terasic Spider is a six-legged walking robot that 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 Terasic Spider. The Terasic Spider itself can be remotely controlled by a Bluetooth enabled Android device. The software app that Terasic 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.

All the source codes of the Terasic Spider are available with the kit. The code can be modified to improve or change the Terasic Spider's functions according to specific applications. The source codes include Android project, Linux application project, and Quartus project.

Note that there is a 2 x 20 GPIO expansion header available on the DE0-Nano-SoC board. It can be used to expand functions, such as a camera, ultrasonic, or anything else.
