List of materials:
If you have created this torch pointer, you already have the electronics and some of the ancillary elements to create your B-robot EVO and a iBoardbot! (yes, we have used the same items to create them ;-D ).
Take a look to the B-robot EVO (The fastest self balancing robot created with a 3D printer)
And to the iBoardbot! (an OPEN SOURCE internet remotely controlled drawing robot)
all the JJrobots are OPEN and can be modified as much as you want!
