Winter is here...brrr. We've been working on getting our visual teach and repeat navigation framework to work in some difficult conditions. Snow is one of those conditions. It's terrible for both traction (lots of wheel slip) as well as vision systems (very few stable features and changing geometry from one day to the next). Multiple cameras seems to help quite a bit and we hope to have some results of this testing submitted to the next edition of Field and Service Robotics, which will be held in Toronto in June, 2015.
