Hello I'm a big fan of openbuild. Its components are great for most linear applications. but now i want to go further and build my own serious robotic arm. I'm struggling to find open robotic mecanic joint and have little metal machining available (as in aluminium or steel) to build my own. It's also the reason why i love openbuild. The best alternative I have found until now looks like below (from igus) (please ignore the stepper motor in the image as i intend to use my own motoring solution) Do we have a chance to see appearing on openbuildspartstore.com any time soon ? How can i help to see that happening ? cheers fourchette source: igus® Blog INT | RL-D 4 DOF standard arm "big"
