Toward Geometry-Scalable Whole-Body Touch for Humanoids: A 3D-Printed Conformal EIT Skin
Haofeng Chen, Carson Kohlbrenner, Jiri Kubik +6
Whole-body tactile sensing is a prerequisite for humanoids that operate in contact-rich human environments, but conventional taxel arrays scale poorly with surface area, wiring com…
Improving Sensing Coverage and Compliance of 3D-Printed Artificial Skins Through Multi-Modal Sensing and Soft Materials
Carson Kohlbrenner, Caleb Escobedo, Sayak Ray +5
3D-printed artificial skins are a scalable approach to whole-body tactile and proximity coverage, but prior implementations have been limited to unimodal sensing and rigid material…
Egocentric Tactile and Proximity Sensors as Observation Priors for Humanoid Collision Avoidance
Carson Kohlbrenner, Niraj Pudasaini, William Xie +3
Collision-free motion is often aided by tactile and proximity sensors distributed on the body of the robot due to their resistance to occlusion as opposed to external cameras. Howe…
Form-Fitting, Large-Area Sensor Mounting for Obstacle Detection
Anna Soukhovei, Carson Kohlbrenner, Caleb Escobedo +3
We introduce a low-cost method for mounting sensors onto robot links for large-area sensing coverage that does not require the sensor's positions or orientations to be calibrated b…
Design, Mapping, and Contact Anticipation with 3D-printed Whole-Body Tactile and Proximity Sensors
Carson Kohlbrenner, Anna Soukhovei, Caleb Escobedo +2
Robots operating in dynamic and shared environments benefit from anticipating contact before it occurs. We present GenTact-Prox, a fully 3D-printed artificial skin that integrates…
GenTact Toolbox: A Computational Design Pipeline to Procedurally Generate Context-Driven 3D Printed Whole-Body Artificial Skins
Carson Kohlbrenner, Caleb Escobedo, S. Sandra Bae +2
Developing whole-body tactile skins for robots remains a challenging task, as existing solutions often prioritize modular, one-size-fits-all designs, which, while versatile, fail t…
