Ok, I have had a chance to do a little research on the experiment and this is what I found. The stated efficiency is about 40% and the team claims that they will be able to develop a commercial system that will meet FCC safety standards. The demonstrated system ran at 10 MHz.
A few things came to mind while I was reading some of the articles. 10 Mhz is already used for a variety of very important wireless governmental services such as WWV time standards and GPS synchronization signals. Just above this frequency is an amateur radio band that shares the spectrum with other services. So there is more to consider than just safety issues.
As far as use on a robot, this system is being developed for delivery of power and has no provision for tranmsission of control signals, although there are other devices that do that very well. In the future this might be a pretty cool thing to have on the robot if certain other problems are addressed. Keep thinking, we might see this someday.
