Show him a tetra. If he can lift it, show him a center goal if one is available. Have him try to place a tetra. (He probably can. If he were 3'...)
As for the building a robot by himself... Ask him if he means LEGO Mindstorms or a competition robot. If he says a competition robot, ask him how long it would take. If he says less than six weeks, get him aluminum, motors and hardware. Give him a challenge and say, "have this done in six weeks." If he succeeds, put him on the team.
