I like your design and it's simplicity. Don't need a lot of rivet holes in the front and back. Just need the correct amount. Standard 1.5 inch spacing is adequate with the correct size rivet. Since you are cutting the main sheet metal parts you can omit the spacers between the side plates with a series of riveted brackets. I think the brackets are lighter than the round standoffs and provide more surface area to stiffen the frame
You could build in a battery holder to the rear flange. I'm a fan of the staggered round circular lightening pattern. Much easier to manufacture than the diamond pattern. Oh and don't forget the access holes on the side plates to tighten the transmissions to the frame. #25 chain?


I've been trying to get my guys to use the s rail configuration to standardize the mounting of the manipulator but they have been hesitant.
Keep up the good work.
