“Twenty-one robotics teams are returning to Worcester Polytechnic Institute (WPI) for a fifth year to compete in NASA’s $1.5 million Sample Return Robot Challenge. The autonomous robotic competition will take place in two stages, with Level 1 from June 7-11 and Level 2 from Sept. 3-7. The event, part of NASA’s Centennial Challenges prize program, is managed by WPI and hosted on its campus in Worcester, Massachusetts. Teams must demonstrate an autonomous robot that can locate, collect and return geologic samples on natural terrain without human control and within a specified time. Levels 1 and 2 vary in allotted time and sample complexity. Teams must successfully complete Level 1 objectives to be eligible for Level 2.”
