Cerberes is a small three wheel robot that avoids obstacles which it senses with its active infrared sensors.Each rear wheel has its own motor, the single front wheel is not powered. The robot steers “like a tank” by rotating the rear wheels in opposite direction.The sensors are built with infrared LEDs which are running at 36kHz and two 36 kHz remote control receiver modules.When the 36 kHz infrared light from the LEDs is reflected by an object, one of the receiver modules will be triggered, and the PIC16F84 µController will steer the ROBOT away from the objects by reversing one of the motors.

This application explains how to make a light detector for ARobot. This can be used to tell when a light is on or off, whether the robot is inside or outside, or for light following. This is a simple expansion and does not require soldering if using a breadboard. It does assume that you have attached a breadboard and an expansion cable to the ARobot (see the breadboard/perfboard application note). This circuit and the light sensor could be mounted and soldered to a perf board and located to a movable head. [more]

This project’s goal is to produce a robot that will follow a track at a maximum speed possible.An Atmel AT90S4433 serves as brain for this robot. It features a 10bit A/D converter that has a 6:1 demux allowing to sample up to six analog channels one at a time. Currently only two analog sources - both light sensors - are being read.The builtin PWM generator could not be utilitized in this case, because two PWMs are needed to control both engines. [more]

TheOther1 writes:I bought a Sharp GP2Y0A21YK0F Distance Sensor to use in my robot. It was very easy to see the data returned in a serial console window, but I thought it would be cool to see the distance in zones represented by colors from a tricolor LED. Then you would not need to be connected to the computer to tell distance…[more]

This is AVR-based Robot Hardware.The main processor board hosts the processor itself, a buffer stage for driving the infra-red emitters in the eyes, and a second stage amplifier which boosts the signals the eye receives with its photodiodes. Otherwise, the rest of the board is given over to connectors to which the other boards interface.[more]
