GlowTact: Simple and Compact Vision-Based Tactile Sensing with High Sensitivity and Spatial Resolution
Yuxiang Ma, Megha Tippur, Pengfei Ye +4
Vision-based tactile sensors (VBTS) provide rich contact information for robotic manipulation, but existing designs can be hard to simplify and adapt to the size and constraints of…
A Durable Vision-Based Tactile Fingertip for Robotic Manipulation
F. Richard Cottrell, Megha H. Tippur, Edward H. Adelson
Currently available commercial vision-based tactile sensors provide rich contact information but remain vulnerable to abrasion and repeated concentrated loading, limiting their use…
Reactive In-Air Clothing Manipulation with Confidence-Aware Dense Correspondence and Visuotactile Affordance
Neha Sunil, Megha Tippur, Arnau Saumell +2
Manipulating clothing is challenging due to complex configurations, variable material dynamics, and frequent self-occlusion. Prior systems often flatten garments or assume visibili…
RainbowSight: A Family of Generalizable, Curved, Camera-Based Tactile Sensors For Shape Reconstruction
Megha H. Tippur, Edward H. Adelson
Camera-based tactile sensors can provide high resolution positional and local geometry information for robotic manipulation. Curved and rounded fingers are often advantageous, but…
Tactile-Reactive Roller Grasper
Shenli Yuan, Shaoxiong Wang, Radhen Patel +4
Manipulation of objects within a robot's hand is one of the most important challenges in achieving robot dexterity. The "Roller Graspers" refers to a family of non-anthropomorphic…
GelSight360: An Omnidirectional Camera-Based Tactile Sensor for Dexterous Robotic Manipulation
Megha H. Tippur, Edward H. Adelson
Camera-based tactile sensors have shown great promise in enhancing a robot's ability to perform a variety of dexterous manipulation tasks. Advantages of their use can be attributed…
TactoFind: A Tactile Only System for Object Retrieval
Sameer Pai, Tao Chen, Megha Tippur +3
We study the problem of object retrieval in scenarios where visual sensing is absent, object shapes are unknown beforehand and objects can move freely, like grabbing objects out of…
Visual Dexterity: In-Hand Reorientation of Novel and Complex Object Shapes
Tao Chen, Megha Tippur, Siyang Wu +3
In-hand object reorientation is necessary for performing many dexterous manipulation tasks, such as tool use in less structured environments that remain beyond the reach of current…
