We're currently building our AR3 at the office and it's soo much fun! Thank you Chris Annin for all the work and effort you put into the project. So far everything went very smoothly.
Big thanks also to Finland Skis for his european BOM, it helped a lot! (https://www.anninrobotics.com/forum/general-discussion/european-bom-and-supplier-list-for-electronics)
So far it's a lunch time / afterhours project, but our goal is to transfer our software knowledge to make real things move :) (More background information here: https://blog.4eyes.ch/we-build-our-own-robot-4eyes-goes-industry-4-0/)
