After my attempt on proto BOB I'm moving on to my real first FW BOB.

The plan for this one is a 4 wheel drive with a lifter, like S.M.I.D.S.Y. So far this is the lay out for it.

Just need to get a linear actuator and other parts to go with it. Luckily I got some spare MDF boards to use when I get what I need just to make sure the lay out works and a rough idea on the weight, btw the drill motors I'm using are about 440g.

Knowing my luck when I start, I got the parts I need but not the tools.
