Robots assist rescuers in search and rescue operations. The important aspects investigated in this study are the integration of a mechatronic system that will allow for a robotic platform with a vision system. The research collaboration between Argentina and South Africa is discussed with the correlating research areas that each country will investigate to allow for the development and advancement...
In this paper, a novel approach for outdoor survey and navigation is presented using a skid-steering vehicle. In the agricultural field, intelligent farming robotic units able to report the plant health or the terrain conditions are very useful and can help farmers save money on labor and improve the harvest results. This work is based on collecting multiple sensor input data to produce more accurate...
In this paper, we propose a safe navigation algorithm for non-holonomic flying robots. To detect the static and moving obstacles, a sensor network, which consists of some time-of-flight cameras, is deployed in a three dimensional environment. The robot or a server obtains the real-time measurements of the environment from the cameras and calculates a temporarily safe robot path from the robot's current...
This work introduces a wearable system to provide situational awareness for blind and visually impaired people. The system includes a camera, an embedded computer and a haptic device to provide feedback when an obstacle is detected. The system uses techniques from computer vision and motion planning to (1) identify walkable space; (2) plan step-by-step a safe motion trajectory in the space, and (3)...
The inspection robot is an autonomous robotic system for inspecting substation equipment to help or replace workers. In order to do the navigation and obstacle negotiating autonomously instead remote control, a stereo vision based 3D mapping system for the measurement of the environment is development. An original mapping and location system by lacer has applied on the robot for the location the robot's...
Vision-based robotics perception still have a great focus of attention on building systems because of its common availability and low cost. The 3D data produced by the disparity calculation methods in stereo cameras are inaccurate and presents substantial noise. We present here our method to deal with the noisy 3D point cloud produced by stereo camera to build a navigation map and mark obstacles with...
This paper applies an existing vision-based navigation algorithm to a micro aerial vehicle (MAV). The algorithm has previously been used for long-range navigation of ground robots based on on-board 3D vision sensors such as a stereo or Kinect cameras. A teach-and-repeat operational strategy enables a robot to autonomously repeat a manually taught route without relying on an external positioning system...
Obstacle detection and real-time planning of collision-free trajectories are key for the fully autonomous operation of micro aerial vehicles in restricted environments.
In this paper a solution to UAV reduced endurance and autonomous flight is proposed. With a complete on-board solution, based on artificial vision, the developed system is able to autonomously take off, navigate and land, recharging its battery by using a dedicated landing platform, both in indoor and outdoor scenarios. The landing platform includes a passive centering system to correct the landing...
This work presents an algorithm for rapid, automated detection of open doorways using 3D point cloud data. The algorithm has been developed in the context of shared-control powered wheelchairs in which adaptive assistance is provided to individuals who otherwise might not possess the fine motor control necessary to handle potentially challenging activities, such as doorway traversal. In this context...
