EMG-based decoding of grasp gestures in reaching-to-grasping motions

Aude Billard, Silvestro Micera, Elvira Pirondini, Sahar El Khoury, Martina Coscia, Iason Batzianoulis

Predicting the grasping function during reach-to-grasp motions is essential for controlling a prosthetic hand or a robotic assistive device. An early accurate prediction increases the usability and the comfort of a prosthetic device. This work proposes an ...

EMG-Based Analysis of the Upper Limb Motion

Aude Billard, Silvestro Micera, Sahar El Khoury, Iason Batzianoulis

In a human robot interaction scenario, predicting the human motion intention is essential for avoiding inconvenient delays and for a smooth reactivity of the robotic system. In particular, when dealing with hand prosthetic devices, an early estimation of t ...

Recognizing the grasp intention from human demonstration

Aude Billard, Sahar El Khoury, Ravin Luis De Souza, José Santos-Victor

In human grasping, choices are made on the use of hand-parts even before a grasp is realized. The human associates these choices with end-functionality and is confident that the resulting grasp will be able to meet task requirements. We refer to these choi ...

On Computing Task-Oriented Grasps

Aude Billard, Sahar El Khoury, Ravin Luis De Souza

This paper addresses the problem of optimal grasping of an object with a multi-fingered robotic hand for accomplishing a given task. The task is first demonstrated by a human operator and its force/torque requirements are captured through the usage of a se ...

EMG-based learning approach for estimating wrist motion

Aude Billard, Silvestro Micera, Sahar El Khoury, Iason Batzianoulis

This paper proposes an EMG based learning approach for estimating the displacement along the 2-axes (abduction/adduction and flexion/extension) of the human wrist in real-time. The algorithm extracts features from the EMG electrodes on the upper and forear ...

Towards comprehensive capture of human grasping and manipulation skills

Aude Billard, Sahar El Khoury, Ravin Luis De Souza, José Santos-Victor

Grasping plays a central role in our daily life. To interact with objects surrounding them, people use a large diversity of hand configurations in combination with forces ranging from the small ones involved in manipulating a pen for writing, to larger for ...

On the Generation of a Variety of Grasps

Aude Billard, Sahar El Khoury, Miao Li

In everyday life, people use a large diversity of hands configurations while reaching out to grasp an object. They tend to vary their hands position/orientation around the object and their fingers placement on its surface according to the object properties ...
