I know only a little about Atrium but it is geared more towards PC boards. I picture the robot as more of a piece of equipment.

ACADE (AutoCAD Electrical) does a good job laying out components and linking them to the schematics, especially on a panel, but for components on the robot a mechanical software such as Inventor or Solidworks is better for the overall design.

ACADE does not have a "rubber band" feature as such but you can move an entire circuit, copy an entire circuit or save a circuit for later.

I must admit I am biased as I use ACADE most every day at work.
