System Errors

It is easy to realize that most robots do not move to the desired endpoint (Tool Center Point (TCP)) using high-resolution noncontact instrumentation because of manufacturing and assembly errors, transmission system errors, and mechanical wear. This paper presents a robot calibration solution by changing the endpoint trajectories while maintaining the robot’s control system and device usages. Two independent systems to measure the endpoint positions, the robot encoder and a noncontact measuring system with a high-resolution camera, are used to determine the endpoint errors. A new trajectory based on the measured errors will be built to replace the original trajectory. The results show that the proposed method can significantly reduce errors; moreover, this is a low-cost solution and easy to apply in practice and calibration can be done cyclically. The only requirement for this method is a noncontact measuring device with high-resolution and located independently with the robot in calibration.

Aerial Photos

With the rapid development of unmanned aerial vehicles (UAV), the applications of the UAV are more and more extensively, and one of the important applications is aerial search and rescue. Using the UAV for search and rescue can save cost and avoid the risk of personal injury. Nowadays, the UAV usually use analog 1.2GHz, 2.4GHz or 5.8GHz real-time video transmission system. Because of the limited transmission bandwidth, the maximum resolution is only 640*480, which is not enough for aerial search. It is difficult to search and identify the small target by this aerial image with only 640*480 resolutions. Because the mobile devices and 3G base stations are widespread, this research integrated the UAV with a mobile device to perform time lapse photography App. The high resolution (2688*1520 pixels) photo can be transmitted to the cloud server via 3G network. The GCS (ground control station) can receive these high resolution photos from cloud servers. With these high resolution aerial photos, the rescued targets can be found and identified more easily. Using the EXIF (Exchangeable image file format) information of the aerial photo, the GPS coordinate of the target can be acquired.
