Hey everyone I need some help/advice.I am in the process of finishing a tricopter build and and am having problems with stabilization.What I have tried so far is I take take the pitch and roll readings from the ArduIMU and trying to balance out the m
Read more…Greetings all,I've been trying to get the ArduPilot up and running, and have run into a snag. I've gotten the main board to "fly" a mission using the GPS emulator, but when I attach the ArduShield I am unable to get a GPS lock. Any thoughts?Jeb
Read more…Hi guys,I'v spent the last few days studying Kalman filters in IMUs and there's one thing I can't understand:the order in which I integrate the speeds from the gyros is important. Different orders will give different results. How is this problem solv

Read more…Hello Group,I am in the process of planning to build a ground control station. I would like to build something off of a "plug and play system". Anyone from the group that has any ideas or insight would be of great help. Many thanks in advance.Kindest
Read more…Hello all,I'm in the (very slow =P) process of building a UAV right now, and have decided that I would like to build my own sensor system from scratch, for educational purposes. However, I don't have much experience with sensor integration (specifica

Read more…Hi, I'm trying to get started with UAVs, but I'm going to develop my autopilot first before buying an RC plane. What I'm thinking is the following:1. Design autopilot using Simulink2. Use the Arduino RTW target to put it onto the ArduPilot hardware3.
