Geeky Dalek Project

19 May 2017

My geeky idea is a Dalek with object recognition and different behaviors based on what it sees. I have recently acquired two 12'' rc daleks, one functioning and one for spares, and the motor section is actually well built. I will use a RPI3 for the image recognition and an Arduino for the movement and obstacle avoidance, so as not to encumber the RPI too much. Trying to find a viable way to turn an optical mouse into an odometer for motion tracking. Any tips VERY welcome.

You could use a PCA9685 to increase your outputs.

I think I need more inputs than outputs. But that PCA board is wicked, daaaaamn!

You would get the 5 GPIOs, you are currently using as outputs, back as inputs.
Apparently, the USonic detector can be interfaced with 1 GPIO (trigger AND echo/output).

A heap of IIC (I2C) sensors can be put on the IIC BUS (128, I think) using 2 wire data.
SPI could also be used for higher speed, but requires 1 GPIO per sensor to "address"/enable it.

Check out a 9DOF IMU.
