# Example how to use the basic robot class Robot6Axis which represent a 6-Axis # industrial robot. The Robot Module is dependend on Part but nor on other Modules. # It works mostly with the basic types Placement, Vector and Matrix. So we need # only: from Robot import * from Part import * from FreeCAD import * # === Basic robot stuff === # create the robot. If you not specify a other kinematic it becomes a Puma 560 rob = Robot6Axis() print rob # accessing the axis and the Tcp. Axis go from 1-6 and are in degrees: Start = rob.Tcp print Start print rob.Axis1 # move the first Axis of the robot: rob.Axis1 = 5.0 # the Tcp has changed (forward kinematic) print rob.Tcp # move the robot back to start position (reverse kinematic): rob.Tcp = Start print rob.Axis1 # the same with axis 2: rob.Axis2 = 5.0 print rob.Tcp rob.Tcp = Start print rob.Axis2 # Waypoints: w = Waypoint(Placement(),name="Pt",type="LIN") print w.Name,w.Type,w.Pos,w.Cont,w.Velocity,w.Base,w.Tool # generate more.
