revisited after 20 years! by Michael E. Holden This is a project I did in 2002 to make an autonomous car with a single GPS sensor. No compass or IMU, and it turned out that the GPS of the day only sent updates of position, speed, and heading every 2 seconds or so. The solution … Continue reading Low-Cost Autonomous Vehicles Using Just GPS
Sometimes students or other nice people ask about my Ph.D. thesis. Probably just being polite. Well, here it is. I earned my Doctor of Philosophy in Aeronautics and Astronautics from Stanford University in 1999 meholdenphdDownload
Dumbo is an autonomous research vessel constructed by students at Cal Maritime. Dumbo carries temperature, salinity, and dissolved oxygen sensors and makes oceanographic observations in the waters off of the Cal Maritime Campus. This work has been supported by the CSU Council on Ocean Affairs, Science & Technology (COAST). Dumbo is guided by an Ardupilot … Continue reading Dumbo the Autonomous Boat
I had an email request to find this project from 2010... I updated the code too! This project takes the pulse from a paddlewheel boat speed sensor and makes an NMEA output on the serial port. It should work with most through-hull speed transducers, and also with windspeed transducers too. The NMEA stream comes from the … Continue reading NMEA 0183 Speedometer
