EB-85 up close


So the EB-85 really does generate 5 unique velocity and position sentences every second. It's no more sensitive than the EM406. It still has a heavy ceramic antenna. Before flight testing can begin, we have many issues to resolve.

The EB-85 has no status LED like the EM406. New flashing codes for the flight computer are required.

solid - Flight computer running. No IMU.
1 flash - IMU functioning. No GPS data.
2 flashes - IMU + GPS functioning. Calibrating INS.
3 flashes - IMU, GPS, INS functioning.

The last crashes destroyed Vicacopter's electronics tray. A new one has been built.

Resoldered the Micromag again.

Pitch servo had a broken solder ball.

Fixed the new GPS to the electronics table and it finally has a header for when U want 2 reduce weight for manual flying.

With more technical issues yet 2 B solved, the earliest test flight is probably going 2 B Sunday.

The reason we haven't moved forward with neural networks is because every neural network experiment has so far required a simulator simulating physical responses to the control movements. There is no exact simulator for Vicacopter. She would be the first neural network trained by matching existing control movements and that is unlikely to work.

Another possibility is switching in a large number of random weights during a real flight. That would take a real long time.

Another realization is the Neural Robotics copter seems 2 have trouble flying forward real fast. The Rotomotion copter can do 25 knots with its PID loops but can't hover easily.
