ARCSnake V2: Mechanical Adaptations For An Amphibious Multi-Domain Screw-Propelled Snake-Like Robot
Sara Wickenhiser, Lizzie Peiros, Calvin Joyce +9
Robotic exploration in extreme environments, such as caves, oceans, and extraplanetary surfaces, poses significant challenges, specifically locomotion across diverse terrains. Conv…
Stable Tracking-in-the-Loop Control of Cable-Driven Surgical Manipulators under Erroneous Kinematic Chains
Neelay Joglekar, Fei Liu, Florian Richter +1
Remote Center of Motion (RCM) robotic manipulators have revolutionized Minimally Invasive Surgery, enabling precise, dexterous surgical manipulation within the patient's body cavit…
Optimal Motion Scaling for Delayed Telesurgery
Jason Lim, Florian Richter, Zih-Yun Chiu +6
Robotic teleoperation over long communication distances poses challenges due to delays in commands and feedback from network latency. One simple yet effective strategy to reduce er…
Differentiable Rendering-based Pose Estimation for Surgical Robotic Instruments
Zekai Liang, Zih-Yun Chiu, Florian Richter +1
Robot pose estimation is a challenging and crucial task for vision-based surgical robotic automation. Typical robotic calibration approaches, however, are not applicable to surgica…
NASU -- Novel Actuating Screw Unit: Origami-inspired Screw-based Propulsion on Mobile Ground Robots
Calvin Joyce, Jason Lim, Roger Nguyen +5
Screw-based locomotion is a robust method of locomotion across a wide range of media including water, sand, and gravel. A challenge with screws is their significant number of impac…
Autonomous Image-to-Grasp Robotic Suturing Using Reliability-Driven Suture Thread Reconstruction
Neelay Joglekar, Fei Liu, Florian Richter +1
Automating suturing during robotically-assisted surgery reduces the burden on the operating surgeon, enabling them to focus on making higher-level decisions rather than fatiguing t…
