This Mobile Sensor Platform (MSP) includes several minor modification of the 2nd gernation of MSPs. All of the MSPs carry devices which enable imaging, distancing, and wireless communication functions. The Image processing algorithms help the mobile sensor understand its environment. A group of these sensors can be coordinated to better react to or reason about real-world phenomena. Most of the existing sensor network testbeds are fixed. The few mobile testbeds either have limited processing capability that prevents them from running interesting and practical applications like target tracking, sensor deployment, and other mission-oriented tasks; or that they are too costly for group deployment. AICIP group will design and implement a mobile sensor network testbed that can provide sufficient processing capability for both 1-D signal processing and 2-D image processing at low cost (<$500 each platform).

This was a first attempt to make more progress and uncover obvious construction issues. (One step forward two steps back...What a tango this work is...
I've added the universal wheel and motherboard to the MSP. It looks like I'm going to have to move the motherboard back to make room for the camera.
I had to use pins instead of the hex screw as the axle for the wheel since the inner diameter of the L-brackets were smaller than than the outer diameter of hex screw. The length of pin is longer than expected and allows the wheel to move laterally-which may introduce path errors.

My next step is to install the battery, h-bridge and motor to begin testing the alignment of the vehicle as it moves in the x and y directions . I must figure out a way to program the TI Quad Half-H driver. This will be good practice since I'm currently enrolled in a Intro to Digtal Design class.
