up to 18 km/h / 11 miles/hr Operating past 6m has been reported to cause fly-aways. This is probably due to faulty software logic. Past 6m the ultrasonic sensors become ineffective and the drone must rely on other sensors (camera, accelerometer, air pressure) to determine height. Motor cable is disconnected The cable may have become disconnected either externally or internally the pins inside the cable may have become bent by impact This is a regular (relatively) problem reported on Parrot forums Motor may present smoke Motor may feel hot to the touch afterwards Motor has been damaged Upon impact the motor has been damaged. You will need to replace it. The ribbon cable to the downward facing camera may be damaged or become loose. You signed in with another tab or window. Reload to refresh your session.

Drone design: An electronics designer’s point of view Part one Figure 2: The Parrot AR.drone quadricopter has four rotor propellers that enable agile maneuvering as compared to a single prop. (Image courtesy of Parrot) There is a nice teardown article on IFIXIT where I got much of the following information as well as from the AR.drone 2.0 Parrot support site. “Make:” magazine was also a nice source for the following drone information3. I will be using the Parrot AR.Drone versions 1.0 and 2.0 as my primary examples since it is one of the more popular and highly developed technological drones at around a $300 price tag (Even though their lead engineer for the AR.Drone and miniDrone, Yoni Benatar, “blew off” my appointment to meet with him at the CES show in January this year and has not made an effort to re-schedule with me) Other good drones, just to name a few are: 3D Robotics, DJI, and a neat online store for hobbyists called Makershed.

Precision electronics control and auto-stabilization The mother board, contains the intelligence of the aircraft in the main processing unit. The 2.0 version of the Parrot AR.drone design uses a Texas Instruments 800 MHz video DSP (Part # TMS320DMC64x) with a microprocessor unit based on the 32 bit ARM Cortex A8 processor running at 1 GHz. It uses a Linux 2.6.32 operating system and has a 1 GB DDR2 RAM running at 200 MHz. This device also has a camera image signal processor that supports multiple formats and interfaces to a wide variety of sensors. There is also a TPS65023 power IC that can properly power the processor if one chooses. The 1.0 version uses an ARM9 processor running at 468MHz with 128 MB DDRAM at 200MHz, running a Linux OS. Communication between the aircraft and the ground station is done by Wi-Fi (b/g) on AR.drone version 1.0 and Wi-Fi (b/g/n) on version 2.0.  For programming purpose(firmware update, flashing and so on)the connection to a PC is done by a USB socket, two cameras, a Wi-Fi module and a connector for software flashing and debugging.

The ARM processor, running the embedded Linux operating system,  simultaneously manages the wireless communications, visual-inertial state estimation and control algorithms.
