This is what will power the bot. These booster packs from Harbor Freight have a 17ah SLA deep cycle battery in the. And with the coupon, they were $37.99 each. That is about what I can buy just the batteries for online.

I cracked them open and took out the batteries. I may use some of the other components in this project.

The radio set also came in today. I mounted the receiver in the control box with double sided tape. The two antenna leads are supposed to stay 180 degrees apart.
