Eight hours to move 1200 parts? Look on Youtube for flexpicker robot. The Flexpicker gripper can lift odd shaped items and handle things as delicate as pancakes without damaging them. One of the videos shows a pancake packaging line at Honey Top, using a vision system to sort the cakes by size so each package will be as close to the specified wweight as possible. It has a temporary storage shelf for when not enough of the right sizes have come along to make up the correct weight. You'll also find videos of similar overhead three and four link systems with grippers picking up randomly oriented items and arranging them precisely at very high speed. The speed comes from the very simple mechanical design. One arm mounted directly at a 90 degree angle to each motor shaft. At the end of that arm is a ball joint connecting a longer arm and at the bottom end of that is another ball joint connecting to the tool/effector platform. Copy that three or four times and you have a robot with no lash or slop in any direction and capable of extreme speeds and accuracy. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
