Giving tours around the hackspace takes time and effort. So the obvious solution is to build a robot to do it. Here are the details and build log.

Start 27/11/13 Basic base is the blue robot from Real Robots Magazine. I got this from a car boot sale and, at the first Arduino 101 day I fixed my arduino base to the robot. There is loads of detail on the Lpilsley Cybot here.

The Arduino is a Duemilanova with an ATMega328. I might updrage to an Uno if needed.

The motor control unit has been left in to power the motors. Details on the circuit diagram are here.

An audio module MOD-1007 from Embedded Adventures has been added for the tour audio. This uses 3v3, which is taken from the Arduino, although for high volumes this does not have enough current. A seperate regulator might be required. Follow the data sheet to see how to play different files using the serial data lines.

Distance is found using ultrasonic sensors re-purposed from the original Real Robot. These have circuit diagrams here.There is a load more information on how the Ultrasonic sensors (called the "sonar board") works here.

There is also a line follower with a circuit diagram here.
