Handle is a research robot that stands 6.5 ft tall, travels at 9 mph and jumps 4 feet vertically. It uses electric power to operate both electric and hydraulic actuators, with a range of about 15 miles on one battery charge. Handle uses many of the same dynamics, balance and mobile manipulation principles found in the quadruped and biped robots we build, but with only about 10 actuated joints, it is significantly less complex. Wheels are efficient on flat surfaces while legs can go almost anywhere.

In partnership with Anheuser-Busch, and with full support from the State of Colorado, we hauled 51,744 cans of Budweiser from Fort Collins, through downtown Denver, to Colorado Springs. By using cameras, radar, and lidar sensors mounted on the vehicle to “see” the road, Otto’s system controlled the acceleration, braking, and steering of the truck to carry the beer exit-to-exit without any human intervention.

Current and previous single-legged hopping robots are energetically tethered and lack portability. Here, we present the design and control of an untethered, energetically autonomous single-legged hopping robot.
