Machine Perception

Mon, 07 Oct 2024 22:35:02 -0400

Intelligent perception is crucial for versatile robots. The integration of advanced proprioceptive and exteroceptive sensing systems are able to provide comprehensive feedback, enabling the robots to navigate, interact, and resolve challenges in real time within complex and unstructured settings.

Soft Material Modeling

Sun, 05 Nov 2023 17:14:45 -0500

Modeling soft materials is challenging. Collaborating with MIT-IBM Watson AI Lab, we presented and for learning robotic skills.

Robotic Manipulation

Wed, 27 Sep 2023 11:46:02 -0400

We developed novel dexterous robotic hands and control algorithms aiming for human-level manipulation and grasping skills.

ActionSense

Mon, 17 Oct 2022 21:55:31 -0400

ActionSense is a multimodal dataset for human activities using wearable sensors in a kitchen environment.

Whole-Body Motion Control in Real Time

Wed, 07 Jul 2021 11:40:43 -0400

We present a real-time control and planning framework to handle dexterous manipulation tasks that is demonstrated on SMORES-EP and CKBot modular robotic systems.

SMORES-EP

Sun, 04 Jul 2021 16:34:38 -0400

SMORES-EP is a swarm and modular robotic system designed and built at the University of Pennsylvania, and used by researchers at Penn and Cornell. SMORES stands for Self-Assembling MOdular Robot for Extreme Shapeshifting, and EP refers to the Electro-Permanent magnets the modules use to connect.

Variable Topology Truss

Sun, 04 Jul 2021 16:34:33 -0400

Variable Topology Trusses (VTT) are hyper-redundant parallel robots. A VTT consists of linear actuators for the truss members, which are joined at the truss nodes by a special reconfigurable spherical joint. A VTT can significantly change its shape and size, reconfigure by merging and splitting these truss nodes, and execute rolling locomotion.

Aerial Manipulation

Sun, 04 Jul 2021 16:25:56 -0400

The Spiral Zipper manipulator is a low-cost, relatively light but strong manipulator with a large workspace and compact storage space that can be mounted on an unmanned aerial system.
