Trajectory Tracking Control for Robotic Deburring Using Hydraulic Shovel

Trajectory Tracking Control Using a Hydraulic Transformer

Throttling loss of a hydraulic system is a major contributor to the low system efficiency. Hydraulic transformers can potentially be used as an energy efficient, throttle-less control approach for multi-actuators systems powered by a common pressure rail (CPR). The transformer transforms the input CPR pressure to the desired pressure of the actuator instead of throttling it. Regenerative energy...

Model Free Adaptive Control for Robotic Manipulator Trajectory Tracking

This paper considers the problem of trajectory tracking of robotic manipulator system by using model free adaptive control (MFAC). The dynamic linearization technique is first introduced, and then the controller can be designed only by I/O data of the robotic manipulator system via MFAC approach, not includes any explicit model information. With some given conditions for controller parameters, ...

Cad Directed Robotic Deburring

Robots prove advantageous for the deburring of machined parts because they are more repeatable than humans and suffer no fatigue. However, most deburring robots are programmed manually, requiring a large investment in programming time. At the National Bureau of Standards' Automated Manufacturing Research Facility, research is being conducted on techniques to automate robot programming. A techni...

Modeling and control of a new robotic deburring system

A machining manipulator is subject to mechanical interaction with the object being processed. The robot performs the task in constrained work space. In constrained tasks, one is concerned with not only the position of the robot end-point, but also the contact forces, which are desired to be accommodated rather than resisted. Therefore, interaction force needs to be considered in designing and c...
