OpenLH: A DIY (DABOIY) Pipetting Robot

The basis of this post is the uArm Swift Pro from uFactory for $750, an open source robot arm with millimeter level precision in positioning. The folks over at milab have written up a fantastic instructable detailing how to take apart a pipette and hook it up to the robot arm. An approach that I’d like to call DABOIY, or Do A Bit Of It Yourself, which leaves you with a pretty solid end product.

Like all good writeups, milab has a list of materials with a total cost of $976 which includes the very cheap ecopipette. They propose controlling the system with python and blockly and report an average 0.15 uL error in pipetting.
