This paper presents autonomous control, waypoint navigation and the real-time database of aerial images and videos from Unmanned Aerial Vehicle (UAV). The UAV used in our experiments is a quadcopter commonly known as drone or aerial robot. The aerial robot exhibits autonomous flight following the waypoints during the test flights. Our aerial robot is capable of generating waypoints list automatically using its onboard GPS sensor. The video of the environment captured by the onboard small fly camera is transmitted down to the base station via the 5.8 GHz wireless analog video link, which is then received in real time at the base station and processed in the rasdaman raster database system. The ground base station is capable of simultaneously controlling the status and real time data. We also present our innovative approach of integration of the web map service to our intelligent raster database server for the real time data.

In the space robot self-assembling process, the assembling control becomes quite complicated and important for the nonlinear characteristics, which are caused by the dynamic coupling between the arm and the base, and the collision between the target and the assembling hole on the base. The dynamic model of the space robot with target is established firstly, then the Hertz model is introduced as the collision model between the docking link and the capturing cone, and the operational space control is applied to achieve the assembling operation control under the Cartesian space. Through simulating and analyzing the influence of the stiffness coefficient, the soft and hard behaviors during assembling are discovered, which would provide a basis for assembling control and parameter design. The results would have important academic value and engineering significance on space robot achieving on-orbit self-assembling.

A redundant robot has more degrees of freedom (dof) than those required to accomplish a given motion task. This fact allows the possibility of achieving an additional task, such as avoidance of joint limits or singularities, besides the primary one. Different criteria have been proposed in the literature for the selection of such secondary task. The paper first recalls some of those criteria, and then proposes a two-loop scheme for the motion control of redundant robots. In order to validate the proposed scheme, some experiments are carried out in a direct-drive redundant planar arm which has been designed and built in our laboratory.

This paper designs a measurement system of energy consumption for clothes model controlled by robottechnology, the system uses DC motor regulated by PWM regulator to drive the worm wheel reducer and the sinusoidal mechanism, then to drive the robot legs to swing forward and backward in sinusoidal step. The sensors detect the rotation speed and torque of the sinusoidal mechanism, the power and energy consumption. The experiments show the system is high in accuracy, excellent in repetition, and suitable for the further research on the principle and evaluation system of the clothes energy consumption.
