Last week I helped Fred with the prototype 6 Degree of Freedom arm. We Figured out how to connect the transmitter and power to the arm. Now we've been focusing on tuning the controls to have a wider range and move more smoothly.
I've also been looking into the Moitessier HAT for a raspberry pi. This HAT has multiple sensors attached to it such as a gyroscope, accelerometer, magnetometer sensors, GNSS receiver, and AIS receiver. From these sensors, it can provide compass heading, heel, trim, barometric pressure, and other features. We plan to combine a pixhawk and the Moitessier HAT to program and configure an autonomous sailbot.
