Title: Neat robot sorter device
Post by: Admin on April 20, 2008, 06:46:26 PM
This is realtime video of the industrial ABB IRB 340 FlexPicker robotic arm thingy sorting various food items using camera vision. I remember reading awhile back that the patent just recently expired on this neat design, so now anyone can use it :)

Cookie points for anyone who finds the design and posts it here. Thinking about it, it seems to have very simple inverse kinematics . . .

Just 3 stepping motors(or servos for us cheap people) spaced at 120°, like a reversed tripod.
The piston in the middle is like a spring pulling it back in the center position retracted and might smooth out the motion as well....


That's what it looks like for me !

It readily handles 150 picks per minute, corresponding to a cycle time of 0.4 seconds.
With a maximum acceleration of 10 g, the IRB 340 is the fastest robot in the world.
The robot manages up to 180 inch foot inch cycles per minute.

EDIT: it's called parallel or planar motion ,something like that
