The Papilion which is mean butterfly in latin is control system for a simple two-wheeled, differential-steered robot based on ATMEGA169. The hardware consists of the AVR butterfly kit, a chassis which is made of aluminum, the two servo motors and a battery holder (providing 6V), a servo power switch and a little board for [...]
The ATmege16-based Airplane Servo Controller helps model aircraft hobbyist to set up control surface throws on a model aircraft easily. The system directly drives the control signals of the aircraft servos while leaving plenty of I/O for reading push buttons and interfacing with an LCD.
In many applications loss of battery power is a problem causing no real harm. But, this is not the case in radio control (R/C) model aircraft. If the aircraft batteries “go dead” in flight it generally results in total destruction of the model and can represent a safety hazard.
This project will show you how to build single digital controller to drive 32 channel R/C servo. The main component in this project is AVR ATmega8515L and Xilinx Spartan IIE FPGA. The combination between FPGA and an ATmega8515L microcontroller make this project powerful solution for robotics applications, especially multi-legged walking robot project.
