Our group lost one of it's members to graduation in the fall, but two new members have been added. Their names are Brian Pustka and James Ledbetter. Brian is a ME student and James is a EE student here at Tech. A new division of labor outline was created to distribute the work load evenly. The labor is divided as follows:
*Thermal Richard (Brian)
*Materials/Structure Brian (Richard)
*Drive/steering Richard (Tim)
*Sensors Tim (James)
*Communications Tim (James)
*Control systems James (Tim)
*Power systems James (Tim)
*Arm interface distributed evenly among all members
*lander interface distributed evenly among all members
The names in parenthesis are assisting roles. Brian has only one main subsystem due to the amount of work needed in the materials/sturucture section. Revisions of the existing design have begun. Due to the unacceptable power consumption of the DXP15 drive motors, new motor assemblies are being chosen. The structural revisions include implementation of an internal structure to replace the external frame, new wheel designs and new leg and suspension assemblies. The robotic arm has been moved to the top center of the rover. This move along with some minor part shifting has increased the maximum arm length to approx. 1.4 m. It has also decreased the surface area available for solar panels. New placements of the panels are being considered. Time permitting, a minimally functional prototype will be constructed by the end of this term.
Next: Engineering drawings of the revisions will be completed. A listing of all chosen parts, their estimated mass, power consumption and cost will be included in next weeks report. The initial thermal requirements on the system as a whole will be completed as well as an initial thermal design. I will attempt to set up a meeting with the members from TSU to discuss the new revisions and their semester timeline. Tim will set up correspondence with our graduate advisor (Michael Kline) for this term. The initial power system revisions and the initial material selection will be constructed.
