Bipedal robots make sense only because the infrastructure around was made for humans. Wheeled and tracked robots can have trouble though spaces designed for humans. Designing with wheelchair access is mind had to happen on purpose. A small set of stairs or uneven terrain can create a big challenge.

Pretty impressive. The ability to operate 13 miles continuously makes un-teatherd humanoid robots viable for a lot of tasks. Once the AI is developed they could deliver mail or stock items in a department store.

It’ll be interesting to see how long it will be from this race before we see bi-pedal robots completing a full marathon.
