Programming a Robot to Trace a Circle

11/01/2009 10:20 PM

Can anyone help me with the programming codes, for the ABB robot (IRB model), for moving the tool , along the circumference, (to trace a circle) of a vertically placed cylinder, the tool being perpendicular, to the surface at every point.

The problem is i tried teaching the robot (keeping the tool axis in line with the diameter), but while moving from suppose p10 to p20, the tool moves inwards (from p10) then outwards (to p20) ,disturbing the work object. Even tried reorienting the tool with the center as TCP, dint workout..

If anyone can help.. Please do reply.. Thanks

Don't know about specific PLC, but functions are X = cosine and Y = sine from 0 to 2 pi, and they have to be executed simultaneously or sequentially in small enough steps so that you can't tell abberations.

Hi megatool,

Try this.

code to draw a Circle

from Tkinter import * canvas = Canvas(width=300, height=300, bg='white') canvas.pack(expand=YES, fill=BOTH) canvas.create_oval(10, 10, 200, 200, width=2, fill='blue')

mainloop()

--------------------------------------------------------------

The code above is not linked to the site below OK? (As you will see).

--------------------------------------------------------------

This is a drawn circle in ActionScript.

Drawing a basic circle in ActionScript

This link give very detailed directions on what to do. The actual code is not very long but you need to visit the site to get the full benefit of the details.

--------------------------------------------------------------

Take care
