    Default Robotics: Crenn's Third Year Project

    As some of you may have heard from my talking in the chat, I'm currently trying to make a plane/helicopter twin bladed VTOL (think V22 Osprey) as my third year project.

    Our group is made up of 4 people and we each have our specialisations. I'm in the process of designing the electronics and interfacing with everything in the project. We're planning to be using a Atmel ATMega640 running at 16MHz with a complement of servos, speed controllers and more.

    Why am I suddenly making the post tonight? Because we caused a speed controller to burst into flames! How you say? The development board we're using has a voltage regulator dedicated for servos and it's meant to output 5.6v.... it was putting out 9v. We had been working with a normal servo most of time to get the signalling from the micro controller correct and decided to test with a speed controller (After we could control the servo fine) and that's when it popped and burst into flames.

    Pictures to come tomorrow. Time for me to sleep.

    Heheh, I love the smell of burning silicon in the morning. XD

    OOC, what was the reason for the 2-rotor design?

    Because it looks cool and also because we can lift upto 1.5kg (3.3lb) which is enough for all of our equipment.

    Updates will be a little more regular now.

    Ok, fair enough. I was just wondering since from what I've heard the control systems for 2-rotor vehicles are a lot more finicky than for 1- or 4-rotor vehicles. How big is it gonna be to be able to lift 1.5kg?

    About 30 inches or so across including the 11x9 blades.

    Well, things are still happening, I'm currently designing the control board for the plane (and hoping I'm doing it right.) and hopefully I'll be etching it in a few days at the latest.

    Here's a preview of what I've been upto:



    Currently having a problem getting a copy printed out at a high enough resolution. The pads for the micro-controller have blended together, possibly due to the software not being able to print at a high enough resolution (printing at 600 dpi).
