Natural User Interface in Augmented Reality to Control Spot: A Large Scale User Study on Speech and Gesture Control of Robots With The Microsoft HoloLens

The increasing presence of robots calls for a more seamless and information-rich communication method between humans and robots. This paper explores how natural user interface (NUI) modalities, particularly speech and gesture controls, can be used through augmented reality (AR) to operate robots. The increasing presence of robots calls for...

On Game-Theoretic Planning with Unknown Opponents' Objectives

Many autonomous navigation tasks require mobile robots to operate in dynamic environments involving interactions between agents. Developing interaction-aware motion planning algorithms that enable safe and intelligent interactions remains challenging. Dynamic game theory renders a powerful mathematical framework to model these interactions...

Scene Classification for a Mobile Interactive Robot

The use of social robots increased in the past few years. Current technology, however, lacks in deploying a single robot for different applications without the help of a human being. Current solutions are time-consuming, labour intensive and hard to generalize. Being aware of its surroundings, in terms of environment and context, the robot can...

Inverse Optimal Control for robot arm motions: Improving human-robot collaboration by incorporating human characteristics into optimal motion generation

Human-robot collaboration can be improved if the motions of the robot are more legible and predictable. This can be achieved by making the motions more human-like. It is assumed that humans move optimal with respect to a certain objective or cost function. To find this function an inverse optimal control approach is developed. It uses a bilevel...

Performance evaluation of the RYSEN: a 3D overground body weight support system

Body weight support (BWS) systems are widely used in gait rehabilitation. These systems allow patients to gradually increase training intensity and promote independent walking. Currently, there is no standardized method to assess the performance of BWS systems. This work proposes methods and metrics that can be used to assess and compare any...
