Magnetic motion capture sensors (MMCS) are not commonly used for robot control due to the need for complex, resource-consuming calibration to correct error introduced by the magnetic sensor. We propose avoiding such calibration using a rule-based controller that only uses spatial coordinates from the magnetic sensor. This controller uses a sparse look-up table of spatial coordinates and actions conducted by the robot and reacts to the presence of the sensor near reference points. The control method was applied to manipulate a robotic camera to track a catheter-shaped sensor inside vessels silicone models. A second evaluation was done guiding a mechanism to reconstruct catheter insertion in major silicone vasculature models. The robotic camera tracked the catheter by reacting to the sensor within 10 mm of each reference point. The catheter insertion mechanism reconstructed the catheter trajectory by reacting to the sensor within 6 mm of each reference point. We found that the proposed method allowed robot control in a bounded space without having to correct for the magnetic tracker output distortion.

Bionics has greatly improved the development of quadruped robot, in the paper we propose three bionic methods for the quadruped robot. These methods have been used for control method design, gait design and control architecture design. The quadruped robot control method has been divided into two parts, because the four-legged animals change their trot speed by adjustment of step length in swing phase and maintain their balance in support phase; control architecture is derived from the four-legged animals nerve system; gait of quadruped robot is based on event driven, and its trot gait is the same as German shepherd. Simulations and experiments are performed, which prove bionics design to be realizable for the quadruped robot.

The frequence and complex of space exploration activeities makes the life of the spacecraft and on-orbit service technologies becoming research hotspot in recent years. But the limitation of non-renewable fuels makes exploration mission costly and maintenance difficult, so the free floating space robot has its unique advantages. Because the research level and control technology is not maturity, study on the free floating space robot control method is the key theory and technology which is the difficulty that our country now needs to overcome, also, the research is of great theoretical and practical significance. This paper introduct an experiment scara mechanical arm based on the free floating space robot project. Main research contents of this paper include the mechanical structure design, and combining with the characteristic of the free floating mechanical arm , it makes kinematics and dynamics modals of the mechanical arm system, additional, it conduct statics test and dynamic modal analysis, which is to make sure that the mechanical arm could satisfy needs and to study its dynamic characteristics.This topic focus on structure design and mathematical modeling of the mechanical arm, it makes the research of control method and trajectory planning no longer stay on the paper, and makes the research more authenticity and accuracy.

In this research we are trying to find a mobile robot control method for corridor navigation and wall following in a partially known environment, when obstacles trajectory is unknown or information about it is incomplete, and the environment consists of stationary obstacles. Gathering information of the robot traveling is based on IR sensors. The aim of the robot is to select avoidance maneuvers to avoid collision with obstacles.
