About the competition. • “The University Rover Challenge (URC) is an annual international competition hosted by the Mars Society for University and College students to complete a given scenario using a rover the team has built.” • It was announced Fall of 2006. The writing on this slide and Much of the writing on the subsequent slides are from Wikipedia and BYU’s website. I mostly won’t use quotation marks.

So was Nyssa Roderick Brown As was Ellie
A little more history of the BYU Rover.http://en.wikipedia.org/wiki/BYU_Mars_Rover
Some unique things about the project. • It is not a capstone or run by knowledgeable engineering professor. • Professor Allred is more customer than manager. • Students have done their own management and organization. • We are very grateful for the nonengineers/ nonscientist on the project. Leadership, organization & financials.
2010 featured the largest pool of registered teams yet. • The tasks were once again similar, but some now with added complexity: • Emergency Navigation to find a distressed astronaut and deliver a package • Equipment Servicing to read a list of step-by-step commands directing the rover to push buttons, flip switches and plug an electrical plugs into outlets in a predefined order. • Sample Return to search for a location in the area that exhibits signs of extremophiles, return the sample so that it can be analyzed at the base station. • Remote Surveying to find the location of posts placed in the desert using the rover.

BYU’s effort 2010-11 Design Teams on the Rover • Power Team headed up by Daniel Hearn • Com/Radio Team headed up by Mike Borg • Controls Team headed up by Daniel Woo • Chassis Team headed up by Mark Davis • Video Team headed up by Andrew Norgrant There is a need for more.
We need help on the astrobiology task. Sample Return Task:Teams will be given a field briefing by judges to discuss the task site. Teams controlling their rovers shall then select multiple (3-6) sites of potential biological interest within a 0.8 km radius of the start gate. Based upon investigation of the selected sites, teams shall then collect and return a single sample from the site they determine to have the greatest likelihood of containing photosynthetic bacteriasuch as cyanobacteria/blue-green algae, other bacterial colonies such as are associated with desert varnish, as well as other nonbacterial extremophiles such as lichen.
We have: • Robust arm and sensor development • A chemical engineer (we thinking of GC when we get sample back to tent.) We need geologist and someone who wants to be an astrobiologist. • We are wondering about utilizing BYU expertise in hyperspectral analysis to look for likely rocks. (Cameras and narrowband filters.)

The coating on the window on Sojourner’s alpha ray spectrometer –this is a element detector- was made by Yuan Fang at Moxtek. He received his PhD at BYU developing this.
