Laser powder bed fusion (LPBF) is an additive manufacturing (AM) process that uses a high-power laser to selectively melt metal powder that has been spread, layer-by-layer, to create parts with highly complex features. Because of the strong influence that
Increasing the flexibility and general-purpose applicability of robots is a longstanding goal. Several avenues of research are addressing these goals, ranging from integration of multiple sensors to allow robots to perceive their surroundings and adapt
Increasing the flexibility and general-purpose applicability of robots is a longstanding goal. Several avenues of research addressing these goals include hand designs, sensing technologies, control algorithms. As part of the manipulation thrust, there has

Condition-based maintenance involves monitoring the degrading health of machines in a manufacturing system and scheduling maintenance to avoid costly unplanned failures. As compared with preventive maintenance, which maintains machines on a set schedule
The costs of maintenance and the potential effect on maintenance costs from adopting predictive maintenance techniques is not well documented at the national level. A number of data items need to be collected to estimate the costs and losses associated
The existence of tactile afferents sensitive to slip-related mechanical transients in the human hand augments the robustness of grasping through secondary force modulation protocols. Despite this knowledge and the fact that tactile-based slip detection has
