Currently, no. I'm on a modding sabatical so to speak and only do asolutly needed bugfixes.
The repair mechanic will most likely not be implemented before a18 comes out.
Sorry.

I'm not sure if this works with fully destroyed bots, but there should be an option on the robot base to fully heal it if you enter god mode. I know it's a little cheaty but it works until there is an actual repair feature.
