This book contains the proceedings of the 10th FSR, (Field and Service Robotics) which is the leading single-track conference on applications of robotics in challenging environments. The 10th FSR was held in Toronto, Canada from 23-26 June 2015.  The book contains 42 full-length, peer-reviewed papers organized into a variety of topics:  Aquatic, Vision, Planetary, Aerial, Underground, and Systems. The goal of the book and the conference is to report and encourage the development and experimental evaluation of field and service robots, and to generate a vibrant exchange and discussion in the community.  Field robots are non-factory robots, typically mobile, that operate in complex and dynamic environments:  on the ground (Earth or other planets), under the ground, underwater, in the air or in space.  Service robots are those that work closely with humans to help them with their lives.  The first FSR was held in Canberra, Australia, in1997.  Since that first meeting, FSR has been held roughly every two years, cycling through Asia, Americas, Europe.
