I am pretty sure this is too general a reference for credit to be given to any single copyright.
No, the controller, plaid jacket and shorts all point to a Tetsujin 28 parody. Daisuke Kusama uses a special watch to command Giant Robo, and the iconic pose for him is standing on the robot's shoulder, not sitting. (It and Giant Robo have the same creator, so confusion is understandable.)
