Step 8The BeetleBot v2 ( Revisited ) - The back caster
You don't really need a round pearl. You can have the entire robot rest on the bare paper clip.
The other step is to glue the paper clip to the battery holder.
Here is another precaution. The way I have glued the paper clip is not super super.
It will not hold on very well. Be sure to put a lot of glue!
You can glue the paper clip on top of the battery holder.
You remember the problem with the heavy front? You can make a long caster to prevent the front to tilt. ( see picture )
