Many geometric problems of interest to mathematical visualization applications involve changing structures requiring mathematical simulations, such as the moves that transform one knot into an equivalent knot. In this paper, we propose to explore a unique paradigm that makes use of self-deformable object models embedded in mathematical space, supplemented by energy-driven relaxation and user-defined...
The shortage of physicians afflicting developed countries encourages engineers and doctors to collaborate towards the development of telemedicine. In particular, robotic systems have the potential for helping doctors making examination. A very common examination that can be the goal of a robotic system is palpation. Most of the robotics systems that have been developed for palpation present interesting...
A novel approach for stabilization and navigation of swarms of Micro Aerial Vehicles (MAVs) along a predefined path through a complex environment with obstacles is introduced in this paper. The method enables to control large MAV swarms (in literature also called UAV swarms) based only on onboard sensors and without any inter-vehicle communication. The proposed method relies on visual localization...
A stabilization and control technique developed for steering swarms of unmanned micro aerial vehicles is proposed in this paper. The presented approach based on a visual relative localization of swarm particles is designed for utilization of multi-robot teams in real-world dynamic environments. The core of the swarming behaviour is inspired by Reynold's BOID model proposed for 2D simulations of schooling...
In this paper, we discuss an approach for enabling students with a visual impairment (VI) to validate the program sequence of a robotic system operating in the real world. We introduce a method that enables the person with VI to feel their robot's movement as well as the environment in which the robot is traveling. The design includes a human-robot interaction framework that utilizes multi-modal feedback...
Blind spots are a nuisance of everyday driving that cause a significant number of accidents every year. Current blind spot systems mainly take advantage of visual feedback for the driver. However, an active blind spot system physically involves the driver to help reduce the number of overall accidents. In this paper, a force-feedback gas pedal and a force-feedback steering wheel are used in conjunction...
This paper describes a novel approach to interactive power assisting control cooperating with visual information for robotic wheelchair. In the proposed approach, both encoder-based and vision-based reaction force observer are designed for obtaining the virtual force due to the environmental change in the field of view. The vision-based observer using the optical flow field of visual scene can estimate...
In this paper, novel power assist control method is proposed by using visual feedback. In our approach, the optical flow field and disparity of stereo vision are used as self-velocity estimation. Then, we define the visual sensitivity for variable optical flow utilization to realize the operational assist function such as for avoiding dynamic obstacle. By regulating visual sensitivity into the desired...
In this paper, a haptically guided teleoperation system which is based on virtual attractive force is introduced. It is well known that haptic feedback can be used to enhance performance of teleoperation systems. When the end-effector is in contact with environment, force/torque sensors can be used to provide real haptic information to operators. Although it is not necessary to provide haptic information...
In teleoperation tasks, information about the relative posture between end-effector and the object to be grasped is of key importance for human operators. Although visual information plays a major role in monitoring collision and fun-tuning the end-effector towards the object, the operator should make strict observations about the video images to take precautions against collision between robot and...
