Quadrotor (quadcopter) guidance system
Quadcopter autonomous landing example The image on the left shows a quad hx19 transmitter and four ultrasonic sensors attached. Each sensor provides its own unique ultrasonic signature. Sensors are available either as panel mount (flat mount) or angle mount as shown on the quadrotor below. An ultrasonic sensor is mounted on each of the rotor ring, the sensors may also be mounted on the rotor support itself. The quadrator ultrasonic kit is light and miniature, and each sensor is plugged in using a micromatch connector. The Hx19tq has a 2.4GHZ RF link used by the hx19 network system and can also be harnessed for user data communication. A ribbon cable with a TTL serial pin, I2C and SPI can be used to transfer data to and from the quadrotor.

By adding four regular hx19 receivers in each corner on a platform, the quadcopter can be guided to land anywhere on this platform with a precision of a few millimeters. The whole system is low power and battery operated, it is therefore fully mobile. Due to the 2.4Ghz RF link by the hx19tq, the quadrotor can be autonomous or remotely controlled at the user's discretion. Both receivers and the quadrotor have both a unique RFID and a unique USID.

Although it is possible to accomplish this application using the standard evaluation pack, with a standard tag/transmitter on each arm and remotely controlled landing, hexamite is developing a special solution just for quadrotors. If you wish to be selected for beta testing please service@hexamite.com and we will put you on our list. We will keep you posted regarding the finalization progress, and we will select a few individuals from this list for the final testing.
