You could use a PCA9685 to increase your outputs.

Works with Arduino and Pi

Update:

The motor section is taking shape, what's missing is a gyro to calculate rotation and probably a mouse optical sensor to calculate movement. I hope I have enough pins on the Arduino for all these sensors.

UPDATE

found a pretty good path planning library on github: https://github.com/elben/kapal and planning to implement it as follows:

arduino does the basic muscle work, moves and returns position and visible obstacles (ultrasound)

raspberry gradually builds a map of the area and tells arduino where to move. In case of unforseen obstacles the movement stops and the map is updated.

only problem is the code is poorly maintained & commented and hard to understand how to parse the final path list.

onwards!

Hello Ian,

Why do you plan to use an Arduino too? Is not sufficient just the PI ?

Hi Ian,

Interesting project.

As I recall, the optical mouse uses a laser diode and a simple imaging sensor.

If you get one of the laptop mice, you should be able to strip out the sensor and processing chips, remount it in the Dalek base to get X-Y movement info over the USB port.

A wireless mouse would get you position information directly to the RPi, assuming all of the pieces can fit inside the base.

You do realize that you need to add a speaker so that they can blast out "Terminate" when anyone nears the device.
