We present FORGE, a method for sim-to-real transfer of force-aware manipulation policies in the presence of significant pose uncertainty. During simulation-based policy learning, FORGE combines a <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">force
Suction-based robotic grippers are common in industrial applications due to their simplicity and robustness but struggle with geometric complexity. Grippers that can handle varied surfaces as easily as traditional suction grippers would be more effective. Here we show how a fractal structure allows
In robotic applications such as bin-picking or block-stacking, learned predictive models have been developed for manipulation of objects with varying but known dynamic properties (e.g., mass distributions and friction coefficients). When a robot encounters a new object, these properties are often di…
In many robotic systems, the holding state consumes power, limits operating time, and increases operating costs. Electrostatic clutches have the potential to improve robotic performance by generating holding torques with low power consumption. A key limitation of electrostatic clutches has been thei…
Self-recovery is a critical capability for robust, agile robots operating in the real world. Given truly challenging terrain, it is nearly inevitable that, at some point, the robot will fail and subsequently need to recover if it is to continue its task. One critical subset of recovery is standing b…
This paper is an initial step toward the realization of an aerial robot that can perform lateral physical work, such as drilling a hole or fastening a screw in a wall. Aerial robots are capable of high maneuverability and can provide access to locations that would be difficult or impossible for grou…
To properly evaluate the ability of robots to operate autonomously in the real world, it is necessary to develop methods for quantifying their self-righting capabilities. Here, we improve upon a sampling-based framework for evaluating self-righting capabilities that was previously validated in two d
Animals and robots alike face challenges of flipping-over as they move in complex terrain. Small insects like cockroaches can rapidly right themselves when upside down, yet small fast-running legged robots are much less capable of ground-based self-righting. Inspired by the discoid cockroach that op…
This paper addresses the challenge of versatile aerial grasping utilizing suction while considering the limitations of an on-board vacuum pump. It builds upon our patented self-sealing suction cup technology, which allows the exertion of local pulling contact forces for grasping a wide range of obje
