Patent number: 8838272Abstract: A robotic arm control system is provided. In, the robotic arm control system, any three points A, B, and C of an object to be determined are picked, thereby creating an original coordinate system. A robotic arm is directed to rotate around the x-axis of the original coordinate system to reach the points B and C. During the rotation of the robotic arm, the three points A, B, and C are recorded by a visual process. A non-linear mapping relation of the original coordinate system and the operation coordinate system is calculated according to length ratios, an angular ratio, and a differential ratio of the difference of the length ratios to the angle between the line A-B and the line A-C, thereby controlling the movement of the robotic arm according to the non-linear mapping relation. The disclosure further provides a robotic arm control method.Type: GrantFiled: December 22, 2011Date of Patent: September 16, 2014Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Chun-Neng Liao, Shen-Chun Li, Wen-Laing Tseng, Cheng-Hsien Lee, Shou-Kuo Hsu

Patent number: 8823538Abstract: In a method for optimizing an order in which certain points on a circuit board can be tested and evaluated, a coordinate system is established in a circuit diagram of a circuit board, and at least one locating point is preset. When an operator selects a signal path routing within the circuit diagram, the method can display the testing points in the selected signal path routing on a display device. After calculating the distance between each of the testing points and each of the at least one locating point, a group of distances is obtained. By comparing the distances, the minimum distance can be determined from the group of distances. The method further optimizes the order of the testing points according to the distance between each of the testing points and the locating point that consists of the minimum distance.Type: GrantFiled: August 30, 2011Date of Patent: September 2, 2014Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Hsien-Chuan Liang, Shen-Chun Li, Shou-Kuo Hsu
