Test Outcome: September 21, 2008

On September 21, 2008 the N.M.E team gathered to conduct preliminary tests. We began with a test run on an average size parking lot that contained few obstacles. After bumping the vehicle three times and bending the drive-shaft (fig. 1), we agreed that a cleaner and more spacious area

was needed to successfully conduct future tests.

We also began the assembly of the Analog to Digital converter (MCP3208) along with the Parallax LM34 Temperature Sensor and Parallax Memory Stick Data logger onto the Parallax Propeller Micro controller Board (fig. 2). After completing the assembly we decided that it would be best to isolate the Data logger in order to configure the Analog to Digital converter, in order to obtain readings from the Temperature Sensor.

However, we experienced some difficulty in the first programming attempt. We were able to successfully output ‘text’ from the micro controller TV_output port, but we were not able to obtain the temperature readings we desired in binary (fig. 3). As of 9.22.08 we have resolved this issue.

As previously stated we are working with Team Associated TC3+ car model. This car was chosen for its sturdy features and the amount of space it provides to mount our project board. Below detailed pictures are provided to demonstrate target areas:
