The re:MARS conference focuses on Machine learning, Automation, Robotics and Space. Similar to the invitation-only MARS conference that it evolved from, the larger and public re:MARS conference brings together industry leaders from across these four domains. It also includes a Tech Showcase where companies can demonstrate their products and ideas.

James found the MARS conference super-interesting, and we were both looking forward to re:MARS in Las Vegas. Besides attending the several excellent keynotes, we spent time in the Tech Showcase where the many demonstrations and displays included an Indy Autonomous Challenge car, pictured above. And we had a great time watching a BattleBots tournament, where robots attempt to destroy or disable each other during one-on-one three-minute matches. Overall, we really enjoyed the event and Jennifer was particularly impressed at how far robot technology had advanced.

Tye Brady, Chief Technologist of Amazon Robotics, on stage during the re:MARS conference Day 2 keynote with Agility Robotics bipedal robot Digit. The robot is targeting repetitive human work that can be more cost-effectively and safely done by a robot. Rather than redesigning the workspace to fit the robot, Agility designed a robot that is able to work safely around people and can take on process paths designed for humans.

James spent time with the Agility Robotics team at the MARS conference and was impressed with its capability. Here’s a video of Digit at work:

The highlight of the re:MARS after party was an exciting and entertaining BattleBots robot tournament, where robots attempt to destroy or disable each other during one-on-one three-minute matches. The matches take place in a large plexiglass-enclosed cage to protect the viewing audience. In this picture, the match-winning blue robot Blip at bottom left has flipped the robot Whiplash several feet in the air.
