A Novel Approach To The Part Orientation Problem For Robotic Assembly Applications, Brian James Slaboch
A Novel Approach To The Part Orientation Problem For Robotic Assembly Applications, Brian James Slaboch
Master's Theses (2009 -)
SCARA (Selective Compliant Assembly Robot Arm) type robots are the most common type of assembly robots. These robots have four degrees of freedom (three rotational and one translational). Typically these robots are used for assembly tasks that take place along a vertical axis. Many times, however, assembly tasks take place along a non-vertical axis. To account for non- vertical axis assembly, parts must be fed in a proper orientation to allow for correct assembly. Parts feeders and specialized end-effectors are typically used to feed parts in their proper orientation. This thesis investigates a novel end-effector that can be used to …
Development Of A Velocity Metric For Rigid-Body Planar Motion, Luis Ernesto Criales Escobar
Development Of A Velocity Metric For Rigid-Body Planar Motion, Luis Ernesto Criales Escobar
Master's Theses (2009 -)
Two motions of motion quality have been developed for planar motion. They are the "best motion measure" and the "velocity metric". The "best motion measure" identifies the best motion for a given displacement. The "velocity metric" quantifies the discrepancy between two planar motions for the same rigid body.
The best motion measure compares the motion of each particle on the body to an "ideal", but usually unobtainable, motion. This ideal motion moves each particle from its current position to its desired position on a straight-line path. Although the ideal motion is not a valid rigid body motion, this does not …
