You can 3D print this robot too. He has the design files available for download. What sets his robor arm ahead f all the other similar projects (there are MANY) is that he specified very heavy duty taper roller bearing in place of the more common deep groove barings.
Once you have a sturdy arm with good bearing, then he connects standard gear-reduced stapper motors as sold at "stepper-online." The printed arm with steppers is good enough for many tasks But with robots, always the bottleneck is software. His software is primitive s you'd be on your own.
