hume: the rough terrain biped
Bookmarked 728 weeks ago the human centered robotics laboratory at ut austin and meka robotics present hume a bipedal robot for rough terrain locomotion hume has been designed to achieve the skill of human centered hyper-agility hcha in particular the extrema of hcha includes free-running-like capabilities on near-vertical surfaces hcha is a very important capability because of its direct impact in the design of human assistive devices for all terrains and the design of next generation semi-autonomous bipedal robot to design hume we conducted computational simulations of rough terrain locomotion compared them with human subjects moving nimbly in the same terrains designed a high performance modular series elastic actuator sea and built a 6 degree of freedom 15 kg biped that can achieve 10 rads of angular speeds and 100 nm of joint torques the robot is designed for interacting with human scale environments at human like speeds to facilitate this capability each actuator utilizes series elastic elements for high bandwidth force sensing and rugged impact tolerance to maintain low leg mass and allow for quick maneuvers the actuators are located as high and near the center of mass as possible packed into the center of the torso are the leg abductionadduction actuators while the hip exionextension actuators ride just above the hip039s center of rotation this conguration keeps the knee exionextension actuator as the only mechanism located on the leg and thus minimizes swing inertia and provides for an overall lighter leg each joint of the biped is driven by a modular series elastic actuator sea the design utilizes a ball screw as the major transmission component providing an efcient high gear reduction while maintaining a low rotational inertia the ball screw drives a set of stiff springs that decouple impacts and provide force sensing this whole spring assembly rides along on special linear bushings that are able to auto compensate for any misalignment thereby reducing friction for the exionextension joints the sea output is then attached to cables that drive the joint while the abductionadduction actuators use pushpull rods to maneuver the leg |
