SCALER: A Tough Versatile Quadruped Free-Climber Robot
Yusuke Tanaka, Yuki Shirai, Xuan Lin +5
This paper introduces SCALER, a quadrupedal robot that demonstrates climbing on bouldering walls, overhangs, ceilings and trotting on the ground. SCALER is one of the first high-de…
Simultaneous Contact-Rich Grasping and Locomotion via Distributed Optimization Enabling Free-Climbing for Multi-Limbed Robots
Yuki Shirai, Xuan Lin, Alexander Schperberg +4
While motion planning of locomotion for legged robots has shown great success, motion planning for legged robots with dexterous multi-finger grasping is not mature yet. We present…
Adaptive Force Controller for Contact-Rich Robotic Systems using an Unscented Kalman Filter
Alexander Schperberg, Yuki Shirai, Xuan Lin +2
In multi-point contact systems, precise force control is crucial for achieving stable and safe interactions between robots and their environment. Thus, we demonstrate an admittance…
Robust Pivoting: Exploiting Frictional Stability Using Bilevel Optimization
Yuki Shirai, Devesh K. Jha, Arvind Raghunathan +1
Generalizable manipulation requires that robots be able to interact with novel objects and environment. This requirement makes manipulation extremely challenging as a robot has to…
Chance-Constrained Optimization in Contact-Rich Systems for Robust Manipulation
Yuki Shirai, Devesh K. Jha, Arvind Raghunathan +1
This paper presents a chance-constrained formulation for robust trajectory optimization during manipulation. In particular, we present a chance-constrained optimization for Stochas…
