Push the Talking Trash Can
Push the Talking Trash Can is a radio controlled robot which makes occasional rounds throughout Tomorrowland inside the Magic Kingdom theme park at Walt Disney World in Orlando, Florida USA; Disneyland park, Disney's California Adventure park in Anaheim, California USA and Hong Kong Disneyland park in Hong Kong.
Push is an actual Tomorrrowland waste container and is so named because of the large word "PUSH" found on either flap. The radio control system is hidden by the bin's regular steel liner and plastic trash bag should a guest peer inside.
The robot is discretely operated by a "cast member" in plainclothes who operates the direction of the robot and provides its voice. The transmitter is hidden inside a large gym bag. A voice processor changes the operator's voice to a high-pitched, nasal register. Since the operator is so close to the robot, he/she is able to make Push interact directly with guests.
Exact technical details are uncertain, but the robot appears to be propelled with the transmission, wheels and tires of a mobility scooter, the type of which Disneyland and Walt Disney World rent in large numbers.
