I’ve added the top chassis plate to my hexapod. I glued 16 blue leds to it and then soldered wires to the leds. The wires are connected to 2 74HC595 shift registers. My hexapod needed some sensors so I mounted 3 small servos to it. One in the bottom plate that sweeps a SRF06 ultrasonic sensor. On the top plate I mounted a pan/tilt kit with a SR04 ultrasonic sensor and a Rocket brand studios Wiicamera. I glued another 2 blue leds to the pan tilt kit. These are controlled by 2 PWM pins. All the sensors and leds are controlled by the Seeeduino Mega, so a 16MHz 8 bit micro controller is more then fast enough to control a total of 21 servos and some sensors.
I now need to learn my hexapod some tricks based on the sensor input
