Robotic screwdriving offers numerous advantages to manufacturers, such as flexibility and repeatability. However, it’s easy to underestimate the requirements of automation. Sometimes, engineers specify the wrong type of robot or overlook parts feeding issues.
“Several issues that need to be addressed before we [will] see more widespread use of robotic screwdriving equipment,” claims Kevin Buckner, design engineer at Design Tool Inc. “These issues include cost, robot design, training and culture. Obviously, as robot costs decrease, their use will become more prevalent. Also, as robot designs increase inertial load levels, the fastener size vs. cost relationship will become more favorable.
