Granett has designed a 70-foot-tall robot called BugJuggler that can juggle three cars, namely a Volkswagen Beetle that weighs about 2,700 pounds.
Here's how Granett says BugJuggler will work: "BugJuggler will use a diesel engine to generate hydraulic pressure. An operator located in the robot’s head will be able to control its motions using a haptic feedback interface connected to high-speed servo valves. Hydraulic accumulators - essentially storage batteries for hydraulic fluid - will allow for the rapid movement required for the robot to juggle cars or other large, heavy objects."
According to the DailyMail, "BugJuggler would also operate within a 'safety radius,' in case a car is dropped."
The first stage of the BugJuggler project will be construction of a working 8-foot-tall, single arm prototype that can toss and catch a 250-pound object.
Granett and his team are currently seeking investment for the project, which he estimates will cost $2.3 million.
