Your thinking on the wrong lines here as far as I see. First off, the kerbals don't have a parachute, nor should the robots. Second, the robots are only for exploration and or repair, not like Wall-E where they do everything. I mean, what would be the point of setting up manned missions if a robot could do it. Yes you guys will come up with some other reasons. Anyhow, I think that the robots real purpose should be that it is maintenance - for example, I set up a Munbase. Whilst its dark, the robots receive a Module - the kerbals can't do anything with it. SO the robots move the module, dock it together, attach things together and in the Munar morning, they have a new module to store snacks. I think that its a good principle but it just needs to be tamed a little, cleaned up a little, then tested. Also, could you draw up a 2.5m similar to but not the same as habitat structure but for, well, structure please?
