System Block Diagram

 

The efforts of our team have been restricted to the design of the above motor controller system. The motor controller is comprised of a microcontroller, a joystick, optical sensors, indicator lights, a USB connection to the PC, a power supply, and motors and their associated encoders.

The two motors being controlled are referred to as the right ascension, which can roughly be considered a longitude position, and declination, which can similarly be roughly interpreted as a longitude. The selected Applied Motion STM17R-3NE stepper motors come with built-in quadrature incremental rotary encoders which help us track the telescope position in real-time and send back signals to the PC indicating whether the desired position command was successfully executed. The encoder counts are tracked and processed by our ATMega 2560 microcontroller, which is also responsible for sending the pulse frequency modulation (PFM) commands to the motors, among other functions. The optical switches and joystick were added features to our design to further model the current system at the Robinson Observatory and to add layers of control and safety to our project's operation.
