• LEGO MINDSTORMS NXT robot, such as the NXT Base Set (5003402) for $159.98 at https://shop.education.lego.com/legoed/en-US/catalog/product.jsp?productId=5003402&   isSimpleSearch=false&ProductLine=NXT. Specifically, the LEGO NXT motor, LEGO NXT brick and LEGO pieces are needed to make the walker robot. These can also be individually purchased at https://www.bricklink.com/v2/search.page?q=LEGO%20NXT%20motor#T=A; one robot per group is ideal, but if not enough are available, share one or several robots amongst all teams, taking turns running the experiment at the front of the classroom)

• computer, loaded with NXT 2.1 software

• ruler or measuring tape
• Arctic Robot Worksheets, one per student
• computer with internet connection
• colored "job" bracelets, 3 per group, of 3 different colors (for example, re-usable silicone rubber bracelets purchased online at reasonable prices, such as http://www.speedywristbands.com) or make from construction paper, although rubber is more durable and can be used again or similar activities)
• graph paper with squares that are 1cm x 1cm
• (optional) colored pencils and/or markers
