I bet it would be a really interesting combination if you combined this technology with the mechanical willy robot from one of the earlier articles. Hmmmm….

That was a dead-end for quite a while. Waveguides have limited bandwidth (about half of the operating frequency) and fairly high loss. Plus they are tubes which are fairly rigid. Corners are a real problem. It just got swamped by fiberoptical systems which work for many kilometers without an amplifier and provide the bandwidth of waveguide based systems for every single wavelength.
