Rover Subsystem - Texas Tech 3/8/96 Progress Report
From: Richard Eddings richeng@HUB.ofthe.NET
1. Begin assembly of a test setup for the drive & steering motor assembly
2. Finalize order of prototype parts
I finished the drawings for the wheel assembly to be used
for the test setup. This design is the actual design proposed for
the rover, so the tests should provide us with some very valuable
information the actual performance of the subsystem. The detailed
drawings are included in the attached file "Wheel.dwg".
The thermal calculations were worked on. The initial insulation
thickness was determined based on an average value for the Aerogel
density. The value worked out to be approx. 90mm per unit surface
area ( m2 ) per side panel. The steering motors operate flawlessly a temperature down to 4 K.
Therefore, the steering motors will not need any type of
1. Obtained a frame and two B&W cameras from a group working on a similar project.
2. Frame grabber located on campus.
3. Continue work on antenna design ( range and placement )
4. Reviewed arm design
The frame that was obtained will enable the obstacle
detection to be tested soon than expected. Using the frame grabber
and the cameras that are currently in hand has saved money.
Most of the needed information for the antenna design has been
received and work will be completed soon. Information on the arm
design has been reviewed and pasted on to Bill and Michael.
The frame grabber that was originally specified for the prototype was not available with a video multiplexer on the PC104 bus. Since a ISA bus
version ( the MUX is standard on these models) was available on campus, a PC104 to ISA adapter was purchased to enable the prototype to be completed.

1. Completed power flow diagram
2. Updated operational modes power spreadsheet
3. Ordered computer system for prototype rover
4. Researched battery selections
I have ordered the computer system for the prototype rover.
I will complete the final selections for batteries for the rover
design this weekend. Since the prototype computer system will
arrive here shortly, I need to begin some research and software
design for the image processing and obstacle detection algorithms
we will be implementing.
1. Finish an initial frame design
2. Complete an estimated mass spreadsheet
3. Make any necessary revisions to the materials list
I have completed an initial frame design, showing the
basic layout of the structure. An estimated mass spreadsheet
was also completed and is included in the attachment file
"Weight2.xls". No revisions were necessary for the materials list.
mass : 10
power : 25
