We had this brocken Dirty Devil Centrino Vacuum Cleaner. I thought, that the housing would be great to build a robot.
First of all I had to take it appart and do a little dremel work to make space for the batterie and the motors.
I bought 2 wheels in the hardware store
How to attach the wheels to the dc drive motor?
I used 2 hexagonal metal distance sleeves, and an aluminum pipe. I removed the thread vice. With glue I attached the constuction to the axle of the dc motor.
The Dc motors are insirted into a pvc pipe.
The holes of the original wheels have exact the dimension of the pcv tube. So it was no problem to install the motors.
Here a litle drive test. I have simply connect the motors to a batterie.
