Abstract: A method for performing robot dynamic path modification using a remote tool center point (RTCP) coordinate frame, for applications such as material dispensing. A processing tool is fixedly mounted in a workcell and the robot holds and moves the workpiece during the processing. The RTCP coordinate frame is defined at the tip of the tool. A nominal processing path on the workpiece is defined, and a prescribed offset distance from the tip of the tool to the workpiece is defined. A sensor measures the actual offset distance from the tool tip to the workpiece. A controller applies the offset in the RTCP coordinate frame and calculates robot motions causing the robot to move the workpiece nominal path past the tool tip at the offset distance. The controller converts the offset from the RTCP frame to a workcell frame, and performs inverse kinematics calculations to generate robot joint motion commands.

Abstract: The disclosure provides an information transmission method and apparatus. The method includes: carrying a first parameter in physical layer signaling corresponding to a Physical Downlink Shared Channel (PDSCH); and transmitting, according to an indication of the first parameter, a Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) corresponding to the PDSCH, which may be specifically identifying an indication meaning of the current first parameter on a predetermined basis and selecting which positions are used to transmit the HARQ-ACK. By adopting the above solution, a first communication node itself sets a position at which an HARQ-ACK is transmitted, and a second communication node feeds back, according to an indication, the HARQ-ACK corresponding to a PDSCH in time, thereby solving the problem of greater delay for HARQ-ACK feedback in the related art, and ensuring the low delay processing of a service.
