IMDL Spring 2012 LandYachtBot Final Presentation Michael Feliciano
Overview Robot Platform Sensor suite Current Progress To Be Completed Demo Day Weather Forecast Contingency Plan Questions? Comments? Concerns?
Robot Platform LandYachtBot’s mechanical platform is approximately 32” long and 24” wide. Mast stands nearly 4’ tall.
Sensor Suite Conventional sensors: LV-MaxSonar-EZ4 ADXL335 3-axis accelerometer MicroMag3 3-axis magnetometer Special sensors: LOCOSYS LS20031 GPS antenna module Wind Vane MA3 Miniature Absolute Magnetic Shaft Encoder
Current Progress Mechanical platform with removable mast, sail, and servos mounted. Completely overhauled obstacle avoidance code using a second sonar, brake, and LCD screen feedback. Limited control algorithms based solely on wind direction.
To Be Completed Integrate navigation control algorithms with compass and GPS data. Implement a GPS waypoint following system. Build more robust sail with ability for sail- tension control (if time permits).
Demo Day LandYachtBot will attempt to navigate a set of GPS waypoints in the parking lot between the Nuclear Science Building and MAE-C. Waypoints will be arranged such that the Yacht must sail both with and against the wind.
Weather Forecast The current weather forecast for Thursday, April 19 th does not appear favorable for my cause. Winds of 7mph are very likely not enough to propel the Yacht.
Contingency Plan Because the winds are likely not going to be strong enough for my purposes, I will be using an electric leaf blower to provide artificial wind. I will have a foot extension cord, but I will require an outlet to use it.
Questions? Comments? Concerns? mph Fun Fact: The current land yacht speed record is mph (wind speeds during record run were 30 – 50 mph). Record set by land yacht Greenbird (pictured left) on March 26, It was piloted by Richard Jenkins. Note: All credit goes to Wikipedia for information on this slide.
