The paper presents a user study characterizing the effect of vibrotactile feedback on performance and cognitive load during teleoperated robotic grasping and manipulation using an affordable bilateral system with a Leap Motion and vibrotactile glove controlling a sensorized robot hand, showing vibrotactile feedback improves teleoperation and reduces cognitive load especially for complex in-hand manipulation tasks.

The paper presents a pipeline to predict safe robotic grasps of unknown objects using depth and tactile sensing. Three methods are compared to find optimal grasp points during tactile exploration - grid search, standard Bayesian Optimization, and Unscented Bayesian Optimization. Results show Unscented Bayesian Optimization provides higher confidence in discovering safe grasps with fewer exploratory observations. It converges faster to robust grasp points away from edges compared to other methods.

The paper presents an approach using depth sensing and tactile feedback to predict safe robotic grasps of completely unknown objects through haptic exploration and comparing grid search, standard Bayesian Optimization, and unscented Bayesian Optimization, with results showing unscented Bayesian Optimization provides higher confidence grasps with fewer exploratory observations.
