Increasing Acceptance of Haptic Feedback in UAV Teleoperations by Visualizing Force Fields

Haptic interfaces have been developed to assist human operators controlling unmanned aerial vehicles (UAV) be- yond line-of-sight. These systems complement the predominantly camera-based visual interfaces and act like a collision-avoidance system: when nearing obstacles, the operator gets re-directed by the haptic force feedback. Previous...

Increasing Acceptance of Haptic Feedback on UAV Teleoperations by Visualizing Force Fields

In tele-operating an UAV human operators fully rely on cameras to control the vehicle from a distance. To increase operator situation awareness and reduce workload, a haptic feedback on the control stick has been developed which acts as an automatic collision avoidance system. A virtual force field surrounding the moving vehicle interacts with...

Increasing Acceptance of Tactile Feedback in UAV Teleoperations by Visualizing Force Fields

Due to the increasing complexity of controlling Unmanned Aerial Vehicles (UAVs), researchers have been trying to let automation take part of the UAV control in order to eliminate human error and reduce the workload of the operator. Such a system has been developed for UAV teleoperators which incorporates haptic feedback on the control stick...

Optic-flow based slope estimation for autonomous landing

Micro Air Vehicles need to have a robust landing capability, especially when they operate outside line-of-sight. Autonomous landing requires the identification of a relatively flat landing surface that does not have too large an inclination. In this article, a vision algorithm is introduced that fits a second-order approximation to the optic...
