10/23/2013: The website is up and running. We made our first verbal presentation last Friday. The Documents section contains a link to the presentation slides. Check back here to see our progress as we work towards presenting a finished project in May.
11/12/2013: The project is moving along well. We are busy looking for parts and trying out some tracking prototypes. Check out the video from our first tracking experiments below. The blinking red light is the beacon (near ir beacon is coming soon) and the blue dot is the position as estimated by the tracking algorithm. Note that right now it is quite sensitive to other lights in the room. Future frequency filtering and background subtraction should greatly decrease this issue.
1/21/2014: Work continues into Interim. The mechanical design of the pointing system is now complete and parts will be ordered soon.
A rendering of the current actuation system design. Two drive belts will link the motors to the moving componenets.
1/21/2014: We were able to control the BLDC motor we found using a controller sampled from Texas Instruments and an Arduino running PID code based on the sensed position of the motor. Check out the video of our tests below.
2/10/2014: Detecting IR beacon using normalized circular cross-correlation. Each pixel is compared to the expected signal at various time delays to determine if it belongs to the IR beacon.
