Visual Feedback for Haptic Assisted Teleoperation of an Industrial Robot: With Dross Removal as a Use Case

Haptic assistance (HA) has been shown to be useful in a wide variety of applications by providing the benefits of automation while keeping the human in the loop. In recent years, providing additional visual feedback has been found to provide benefits to HA interfaces by complementing their advantages and mitigating their weaknesses. However, the...

Feeling Uncertain: Effects of Encoding Uncertainty in the Tactile Communication of a Spatiotemporal Feature

An appropriate understanding of a machine's competences may be critical for safe use. Sharing measures of real-time function reliability could help users to adjust their reliance on machine capabilities. We designed a vibrotactile interface that communicates spatiotemporal information about surrounding events and further encodes a representation...

Co-operation and haptic assistance for tele-manipulated control over two asymmetric slaves

The success of future fusion power plants as a sustainable energy source greatly depends on their uptime. This uptime relies on the plant's maintenance, which must be performed via tele-manipulation. Tele-manipulated maintenance is challenging, as exemplified by strictly selected and highly trained operators who still require more time to work...

Haptic assistance improves tele-manipulation with two asymmetric slaves

Tele-manipulation of heavy loads typically requires the simultaneous use of two asymmetric slaves: a crane for vertical weight support; and a robot for accurate lateral positioning. The industrial standard prescribes a pair of operators for such tasks (one operator to control each slave), although in principle one operator might control both...

Haptic Assistance is a Promising Method to Support Operators of a Hunting Simulator for Training Lions

At the Lion Foundation a hunting simulator is used to stimulate the hunting instincts and skills of lions and tigers, in order to improve their health and increase chances of relocation into the wild. The hunting simulator is an animal enclosure wherein a piece of meat, used as prey, is moved by means of a joystick-controlled cable-driven system...

Applying Dynamic Damping to Robotic Vitreoretinal Surgery

Vitreoretinal surgery remains one of the most challenging types of surgery due to the delicate nature of the eye, the minimally invasive nature of the procedure, the small operating space and lack of depth perception. One of the procedures that is performed during vitreoretinal surgery is Epiretinal Membrane (ERM) Peeling , during which the...

Trust in haptic assistance: Weighting visual and haptic cues based on error history

To effectively interpret and interact with the world, humans weight redundant estimates from different sensory cues to form one coherent, integrated estimate. Recent advancements in physical assistance systems, where guiding forces are computed by an intelligent agent, enable the presentation of augmented cues. It is unknown, however, if cue...
