In view of the problem that traditional collaborative robots mostly work according to the prescribed paththrough teaching or offline programming cannot obtain the feedback information of the robot in real time, resulting in low intelligence. A multi-decision pressure compensation robot massage control system based on stereo vision imaging is proposed. It could reduce the execution time and positioning error of the robot when conducting human body positioning massage, and perform force compensation based on the massage pressure feedback in real time to improve the level of human-computer interaction. Firstly, hand-eye calibration is carried out through binocular vision sensor and collaborative robot, and the robot positioning control is realized by using high-precision real-time point cloud generated by structured light compensation. the massage pressure is fed back through the pressure sensor on the massage end which the massage force is trimmed to ensure the safety and comfort during the massage process. In the visual working range, the experimental data shows that the depth positioning error is within 0.277mm and the accuracy of the robot massage in the appropriate pressure range can reach 97.35%, which effectively solves the problems in robot massage and increases the standard of human-computer interaction and the immersive experience which is made innovations in the direction of stereo imaging technology and medical treatment.

the daily life of stroke patients may be severely limited. In this paper, we proposed a shared control based assistive mobile robot system to improve their ability. Brain-machine interface (BMI) was used for obtaining the user's intention to give a command to the robot. the computervision technology with laser radar and camera was equipped to detect the environment for obstacle avoidance and target recognition. Withthe spatial coordinate provided by the vision part, the robot would grasp the target back to the user eventually. the test was carried out on boththe BMI based console part and the robot executive. the results showed good performance with satisfied BMI accuracy, quite small route planning error, recognition error and motion planning error, which make us convinced that this assistive mobile robot can help the disabled people.

this paper concerns 3D object recognition from vision. In our robotics context an object must be recognized and localized in order to be grasped by a mobile robot equipped with a manipulator arm: several cameras are mounted on this robot, on a static mast or on the wrist of the arm. the use of such a robot for object recognition, makes possible active strategies for object recognition. this system must be able to place the sensor in different positions around the object in order to learn discriminant features on every object to be recognized in a first step, and then to recognize these objects before a grasping task. Our method exploits the Mutual Information to actively acquire visual data until the recognition, like it was proposed in works presented in (Denzler and Brown, 2000) and (Denzler et al., 2001): color histogram, shape context, shape signature, Harris or Sift points descriptors are learnt from different viewpoint around every object in order to make the system more robust and efficient.

In this paper we present a framework for path planning and path finding for multiple mobile robots with global vision. Our framework model considers the agents' dynamic status and their environment with obstacles to perform given tasks. the global vision system provides feedback to main controller computer and mobile robots are directed towards to their tasks with avoiding obstacles and without any collision. Different kinds of scenario are prepared to simulate manipulating tasks and non-collision behavior with our framework. Experiment results with Lego Mindstorms NXT shows that our framework can be used where a multi robot system is needed with minimum resources.

the new creation principle of mobile robot, which working in a complex landscape or on a cross-country terrain is offered. the new technical means for "computervision" realization are proposed. Two problems connected to it are solved: of technical sight system creations for images recognition of an unfamiliar landscape, and direction determination on an initial point of a movement trajectory of the mobile transport robot. Questions of principle design and also about functioning and interaction of units and elements of system are described. the mathematical apparatus for processing the digital information inside system, and also for determination of distances and angular measures in offered system are resulted. the important parameters are analytically determined: expected accuracy, functioning speed, range of action, power questions of use. Conclusions under clause reflect questions of possible areas of practical use of the developed automatic system of navigation.
