I want to build and program the robot as far as possible in the same way as it is done in industry. The robot should have six servo motors for a free choice of the orientation of the effector. Which parts should I buy for this? Should I buy some small servo motors and 3D-print the arm parts and program the controller with an AVR chip? If so, which servo motors should I buy, how should I wire the servo motors, etc? And I don't want to do it with Arduino at all, because I want to learn how something like this is done in the industry.
