Step Right Up or Cower In Fear; the 7-Story Car-Juggling Robot Is Here

Seven story robot juggles three VW BeetlesSometimes we see a project that’s just as frightening as it is awesome. The Bug Juggler is a prime example of this phenomenon. A seven-story diesel-powered humanoid robot is one thing, but this one will pick up two VW Beetles, put one in its pocket, pick up a third, and juggle them. Yes, juggle them.

The Bug Juggler will be driven by a brave soul sitting in the head-cage and controlling him through haptic feedback connected to high-speed servo valves. A diesel engine will generate hydraulic pressure, and the mobility required for juggling the cars will come from hydraulic accumulators.

The project is in the capable hands of team members who have built special effects, a diesel/hydraulic vehicle for hauling huge sections of pipe, and mechanisms for Space Shuttle experiments. In order to attract investors for the full-scale version, they are building an 8-foot tall proof-of-concept arm assembly capable of tossing and catching a 250lb. mass.

If you prefer to see Beetles crushed, check out Stompy, the 18-foot rideable hexapod. Make the jump to see an animation of the full-scale Bug Juggler in action. Don’t know about you, but we wouldn’t stand quite so close to it without a helmet and some really good health insurance.

Robot juggler sure handles a lot of balls

This robot juggler, pictured above during its appearance at Amper 2010, can keep five balls in the air at once. It was designed by the Department of Control Engineering at the Czech Technical Institute in Prague. We know it doesn’t look like much in that still image, but the two videos embedded after the break are pure gold.

To arms on vertical tracks do the juggling. They can move up and down on said tracks, and circular grippers attached to each can pivot horizontally. A third actuator resides at the bottom of the machine, collecting any balls that might drop, and launching them back into the realm of the juggling hands. A high-speed camera facilitates object tracking in much the same ways that it’s been used for quadcopter control.

The objects being thrown around in that protective enclosure are billiards balls. We guess the added mass helps to dampen any small irregularities in the throw or the catch.

The Blind Juggler

The Blind Juggler is a robot that juggles or bounces balls in a controlled manner without any sensory input. It is basically just a linear actuator with a paddle on the end to smack the ball back into the air as it returns to the ground. The crazy thing is, it is doing this based purely on pre programmed math. There are no sensors telling it to make any adjustments. While we could envision this functioning, we would never have expected it to be as stable as it is. You can see in the video above that they can actually move the entire robot around while maintaining the bounce. Also check out the pendulum version, instead of just actuating vertically, it is mounted as a pendulum allowing the ball to travel back and forth in an arc.
