About this project

This is the first and most important step leading to the most amazing robot ever devised!

This working scale model of the giant car juggling robot will use the same sensory feedback controls and scaled down hydraulic components of the full size juggler.  Here is where we test the limits of the speed, strength and agility of the technology. It will toss and catch objects up to 250lb (114kg) in mass.

When completed, those jugglers who will go on to climb 7 stories up into the giant will train here first and experience the feeling of a "phantom" force drawing their hand and arm down while the robot is tossing and catching the real object.

Stretch goal: If we reach $75,000 funding we will purchase an additional set of hydraulic components and build a second arm for a more realistic juggling experience with 3 objects.

Prototype Construction

The BugJuggler prototype will be constructed using structural steel components and off the shelf hydraulic cylinders. High speed servo controlled valves will be used to control the motion of the robot. 

Control Interface

The interface between the BugJuggler prototype and the human operator will consist of a sensor sleeve and glove. In addition to capturing the movements of the operator the interface will provide haptic feedback. When the robot catches a heavy weight a proportional force will be felt by the operator. 

Rewards

The BugJuggler Project

The BugJuggler prototype is the first step toward the ultimate goal of constructing the full size BugJuggler robot. We will use the prototype to refine the mechanical design of the big bot. The interface developed for the prototype will be the basis for the interface of the 70ft tall robot. By helping us build this prototype you will be making it possible for us to take the first, crucial step on the path to building the coolest robot you've ever seen!

Risks and challenges

We have the tools and skills to build this project here in our Berkeley "skunkworks". The off-the shelf hydraulic components are readily available but there is always the issue of parts shortage and shipping times. We have backup sources for all needed parts. There will be some trial and error in sizing the capacities of the valves and cylinders for the arm and wrist motions. We generally over-estimate if there is a question of strength and speed requirements. This will increase the safety factor and lower the chance of structural failures.
If outside technical services are required, the San Francisco Bay Area is rich with such specialties as laser cutting, abrasive water jet, CNC machining, powder coating, etc.
