Testbed for Motion Control

The problems of working directly on the Dalek are:

• It is too big to bring inside (it does not fit through the normal door frame)
• It is a headache working on as everything is inside.
• The skate wheels don't have a lot of traction and the Dalek gets bogged.
• It drains the battery after about 30 minutes.

I really need to upgrade the wheels but that is another project in itself.

The solution is a testbed for the motion control (note the worried dog):

And the underside:

The steppers are 12v so no over current risk with the 12v power supply.

I would like to uses these components on the Dalek but the motor axles and wheels would probably bend or break.

So all I need to do now is mount the Arduino, motor controller and battery pack.
