gait rehabilitation using body weight support on a treadmill is a recommended rehabilitation technique for neurological injuries, such as spinal cord injury. in this paper, a new robotic orthosis is presented for treadmill training. in the presented design the criteria such as low inertia of robot components, backdrivability, high safety and degrees of freedom based on human walking are conside...

Conversational engagement is a multimodal phenomenon and an essential cue to assess both human-human and human-robot communication. Speaker-dependent and speaker-independent scenarios were addressed in our engagement study. Handcrafted audio-visual features were used. Fixed window sizes for feature fusion method were analysed. Novel dynamic window size selection and multimodal bi-directional lo...

The ability to recognize people is a key element for improving naturalistic human-robot and human-computer interaction systems. In this paper, we propose a binary nonsubsampled contourlet transform (B-NSCT) based illumination robust face representation. Faces are transformed into multi-scale and multi-directional contour information where the intrinsic geometrical structures are used for charac...

Traditional two wheels differential drive normally used on mobile robots have manoeuvrability limitations and take time to sort out. Most teams use two driving wheels (with one or two cast wheels), four driving wheels and even three driving wheels. A three wheel drive with omni-directional wheel has been tried with success, and was implemented on fast moving autonomous mobile robots. This paper...

Abstract: This paper describes how to control an asymmetric wheeled mobile robot with omnidirectional wheels, considering the sample of a robot with three wheels. When flexible motion capabilities are required this robot must be designed to meet the related requirements, namely fast and agile motions as well as robust navigation. This paper provides an overview for the design of kinematics and ...

The current pavement sign marking operations are manually carried out, which are labor-intensive. This method requires blocking traffic for a long period of time resulting serious traffic jam. Also, the workers are exposed to possible injury and even death by passing traffic. This paper deals with the development of a robotic system for automating the pavement sign painting operations. The robo...
