Seems to me that "...solely through electric energy provided after the start of DEPLOYMENT..." is pretty darn unequivical. No other form of propulsion energy can be used, even if it is the robot's own potential energy. Just because acceleration from gravity is free does not mean it is allowed. This would certainly qualify as energy other than electric energy, and if I understand the description, would also be partially gained before deployment (before crossing the cylinder of the platform.) This is one of those cases where you are just going to have to live with the "spirit of the rule."
