My QuaXCopter Project. Hi Everyone. I've been working on my Quadrotor project for one year. My last attempt was not good enough to fly. The control board worked well, but... i had problem with the frame. The frame was not enough rigid to absorb the mechanical vibrations coming from the motors. Some months later, I decided to give the project another try, with new changes on the control board and definitely on the frame "the frame will be smaller". Stellaris Cortex-M3 microcontroller (LM3S5749).IMU sensor 9DOF sensor stick.Wireless communication via Bluetooth or RF, (Bluetooth module UART and NRF24L01 module SPI).Temperature Sensor.Sonar Sensor.USB connection. I would like to show you some pics of the control board: The rest of this month and the next one, I will work it on the firmware development. Would accept any suggestion or recommendations. Regards.
FPV flying - RC FPV UAV equipment Fatshark Dominator FPV Goggles Review Fatshark Vision Systems' Dominators are the latest incarnation of FPV (first person view) goggles designed for full-immersion flying. The Dominators come as a complete package, with a built-in 5.8 or 2.4GHz receiver and matching transmitter. For expanded flying, a built-in head tracker allows you to turn your head and have the camera on the airplane mimmic your movements. In case you're not up to speed with the FPV movement, the idea is to use a small camera and transmitter attached to the airplane to send the video signal down to a receiver. From there, it's up to you on how you want to display the video. Fatshark has created a very complete kit, that includes a majority of the items needed to fly basic FPV. The overall fit and finish of the Dominators is very nice. Both sides of the goggles have removeable covers to access the internal electronics. Two 5.8GHz 3dbi antennas are included with the Dominators and are good for short to medium range FPV flying. Internal Receiver Mode Pluses
Home Page Hobby Wireless - FPV RC shop, the best in wireless systems MultiWii additional HOWTO overview 4: MultiWii release descriptions This post just combines the release descriptions of the last revisions. Release version 1.9 1.8 -> 1.9 - some factorizations between PPM sum receiver code & standard receiver code EXPERIMENTAL: integration of direct SBUS receiver thanks to the contribution of Captain IxI & Zaggo For this, you must use: - a MEGA board - the RX1 of the Serial 1 port - have a way to invert the input signal. more info here: EXPERIMENTAL: integration of SPEKTRUM satellite receiver thanks to the contribution of Danal Estes For this, you must use: - a MEGA board - the RX1 of the Serial 1 port It could be used also on ProMini board with some restrictions (exclusive GUI or Spektrum use) more info here: EXPERIMENTAL: integration of direct Serial RX, to command the multi from a Bluetooth+phone Signal for instance. thanks to Luis - many optimizations to reduce loop cycle - all in one FC: Quote:
Building a palm size quad-copter & Introducing a new simple flight controller Build the frame: I cut the aluminum tubes down to 10" long. I guess I can cut it shorter, but let's see how this go. One arm is now cut by half. The two half's are joined together with the other uncut arm to form a cross. They are then hot glued and screwed to 2 pieces of hobby ply wood (1/16" thick) And the finished frame: Drill holes that fit the motor mount & cut the two arms that would be the front and the back of the quads. The cut is necessary so that I can tilt the front and back motors. Tilting mechanism I found some aluminum tubes (also at local hobby shop). I use a heat gun to heat both the tubes and then I put some hot glue into the tubes, and then the round tubes are pressed inside. I tilt both of them about 8 degrees. The hot glue can be then melt with a heat gun so that I can twist to adjust the tilting angle. Install motors & ESC's 4 ESCs Power distribution I cut two pieces of copper clad PCB.

HXT Simple Lipoly Monitor 2S~3S. A must have for all lipo users! Excellent item, barely weighs 3 grams with leads to battery. I have found that if you remove the SMC resistor connected to the red LED, the LED is ALLOT more brighter. Before I removed the resistor it was a dull red when the voltage drops below 3.3V/per cell, now it can't be missed, either during day or night flight. I also found out that my charger was not balancing my cells properly and one cell would drain faster then the others, this item indicated that one cell was drained compared against the other cells. Save me from completely destroying my Lipo packs :-). One down side to this item is that it does not provide a way to determine voltage between 3.7-3.3V/per cell. Still great tool to have on board.
Heavy-Duty Quadrocopter - Imperial College Robotics Society Wiki From Imperial College Robotics Society Wiki Imperial College Robotics Society ( ICRS ) is a student-led university club aiming to increase robotics interest at Imperial College London and across the UK. We run workshops, competitions and lectures to teach about robotics, electronics and software as well as providing help (financial and technical) to students looking to start a robotics project. Our club was founded in November 2009, and since then we have entered a few student teams into the Eurobot competition, built 2 RepRap 3D printers and created a quadracopter with a fully 3D-printed chassis. ICRS is always looking for new members that want to learn about robotics or create cool projects. Projects For a full list of ICRS's projects, or to propose your own, please visit our projects page . ICRS-ARM Robotics Workshop 2012 ARM ran a fantastic Robotics Workshop at Imperial on the 7th of March! ARM Robotics Workshop ICRS Megabyte Talks Robotics Courses About ICRS
