LIKO: LiDAR, Inertial, and Kinematic Odometry for Bipedal Robots

ICRA 2024poster

High-frequency and accurate state estimation is crucial for biped robots. This paper presents a tightly-coupled LiDAR-Inertial-Kinematic Odometry (LIKO) for biped robot state estimation based on an iterated extended Kalman filter. Beyond state estimation, the foot contact position is also modeled an…

Design of Robot Leg with Variable Reduction Ratio Crossed Four-bar Linkage Mechanism

IROS 2019poster

Generally, large knee joint torque is required when a leg is flexed. However, the large torque motor will increase the robot size and total weight. Also, a large reduction ratio gear box to realize the large torque will decrease output speed and lower backdrivability of the joint. It makes the robot…

Cat-inspired mechanical design of self-adaptive toes for a legged robot

IROS 2016poster

Cats have protractible claws to fold their tips to keep them sharp. They protract claws while hunting and pawing on slippery surfaces. Protracted claws by tendons and muscles of toes can help cats anchoring themselves steady while their locomotion trends to slip and releasing the hold while they ret…
