Robot Programming Techniques

robot programming on the teach pendantMotion Controls Robotics recently received a question from a fellow Twitter follower. The follower asked, “Outside of the teach pendant, how are robotic movements typically programmed?“  Since this answer obviously contains more than 140 characters, we wanted to share some robot programming information with all our followers through a Tech Talk article.

It is a typical sight on the MCRI design floor to see a Programmer positioning a robot in relation to other items in the system with a teach pendant. The teach pendant can be used to manually program points and move the robot almost like a remote control. Teaching a robot means programming precise positions (movement) and procedures.  While this manual controller is easy to spot and commonly used, there are a variety of other programming techniques that can also be used to program the robot’s positions.

Robot Programming

  • CAD to Path – operator gives a robot the ability to perform certain functions by defining part geometry in CAD and downloading it to the robot controller – to paint a car, weld a seam, or grind the edge of a product for example. FANUC has a very informational web page describing CAD to Path programming and comparing and it to CNC processing.
  • ROBOGUIDE – PC software designed to simulate the physical robot and the equipment it will interface with. Programming can occur on the Virtual Teach Pendant available through the ROBOGUIDE software. Actual real world robot programs can be loaded into ROBOGUIDE and the programmer can make program changes and additions using the software and then load these files into the real world robot. Programs created or modified in ROBOGUIDE can be ran and tested in the virtual world using the software.
  • Some robots can be manually guided through motions, with input buttons used to record or mark start and finish points of moves, and to identify where other functions need to be performed such as gripping or releasing a part. guided robot programming FANUC’s new collaborative CR-35 robot allows programming through manual manipulation at the end of arm tool.
  • Robots that are already programmed to handle specific parts and perform specific functions can be parametrically told to handle similar parts with different dimensions, or case pack or palletize in a different pattern, or insert screws into a different shaped product.  The integrator needs to create the parametric programming up front and load it into the robot’s controller, then provide a means for an operator to add parts and new part parameters (usually through an HMI operator screen).
