Dynalog’s Dynacal system has been selected by a Japanese auto maker in the US for recovery of their robot programs after a crash, moved fixture, replacement of robot motors, and replacement of end-effector. A reference signature of the robot-cell is acquired with the DynaCal system when the robot-cell is performing its production job accurately. After a change in the robot-cell, e.g. tool crash, the DynaCal system is utilized to identify the difference in the robot-cell signature compared to the reference signature. The differences are updated in the robot controller, i.e. TCP, User Frame, and Zero-Position-Mastering are updated in the robot controller, which recovers the robot programs to its previous accurate state.
