Description

Cam operation can make 1 or more axis of the slave XBot follow the motion of 1 more axis of 1 or more master XBots.

  • It is not necessary to follow the same axis (you can use the Y axis motion of the master XBot to drive the X axis motion of the slave XBot

  • The way the slave XBot axis follows the master XBot axis is user defined in a text file, please see Cam Configuration instructions

 

Behaviour During Obstacles

If the slave XBot encounters an obstacle (i.e. another XBot is in the way) while following a cam, it will stop following the master and go back to the Idle State. Its motion will not be resumed even if the obstacle XBot is moved away.
