چکیده

We propose an experience-based approach to the problem of blind grasping, stable robotic grasping using tactile sensing and hand kinematic feedback. We first collect a set of stable grasps to build a tactile experience database which contains tactile contacts for each stable grasp. Using the tactile experience database, we propose an algorithm to synthesize local hand adjustment that controls the hand pose and improves the grasp based on tactile sensor readings. Simulation experiments show that local adjustment of the hand improves the grasping performance.

High-speed sensory–motor fusion for robotic grasping

In this paper a new high-speed vision device and its application to a grasp system is proposed, and we discuss a processing architecture for grasping based on visual and tactile feedback designed with real-time control in mind. First, we describe a high-speed vision chip that serves as a robotic eye that includes a general-purpose parallel processing array along with a photo-detector all on a s...

Improving grasp performance using in-hand proximity and contact sensing

We describe the grasping and manipulation strategy that we employed at the autonomous track of the Robotic Grasping and Manipulation Competition at IROS 2016. A salient feature of our architecture is the tight coupling between visual (Asus Xtion) and tactile perception (Robotic Materials), to reduce the uncertainty in sensing and actuation. We demonstrate the importance of tactile sensing and r...

Using tactile and visual sensing with a robotic hand

Most robotic hands are either sensorless or lack the ability to accurately and robustly report position and force information relating to contact. This paper describes a robotic hand system that uses a limited set of native joint position and force sensing along with custom designed tactile sensors and real-time vision modules to accurately compute nger contacts and applied forces for grasping ...

On the Variability of Tactile Signals During Grasping

Robotic manipulation in unstructured environments must handle a wide range of objects despite errors in visual perception. Tactile sensing is presumed to provide essential information in this context, but there has been little work examining the tactile sensor signals produced during realistic manipulation tasks. This paper presents tactile sensor data from grasping a generic object in hundreds...

Integration of Vision, Force and Tactile Sensing for Grasping

Most robotic hands are either sensorless or lack the ability to report accurate position and force information relating to contact. This paper describes a robotic hand system that uses a limited set of native joint position and force sensing along with custom designed tactile sensors and real-time vision modules to accurately compute finger contacts and applied forces for grasping tasks. A numb...
