I elected to build the RC controller from designs freely available on the Internet. The controller uses an inexpensive PIC16C84 microcontroller. Still, I was tempted to buy the commercial Mini SSC II and MotorMind boards (discussed later) because of their compact size and specifications. I may go with the commercial boards in the future for additional devices in my animation system. If cost is not an issue and you would like to get the animation system up and running quickly, the only board that you may want to build is the PIC-based joystick controller board.

The residual lightning and ESD pulses as well as the remaining interference signals are attenuated before entering the clean cavity by the LC filter. com CIRCUIT CELLAR® Issue 142 May 2002 33 ROBOTICS CORNER Daniel Ramirez Behind the Scenes Part 1: Controlling an Animatronics System w Hollywood is one of the biggest markets for automation systems, but beneath the makeup lies a number of engineering challenges. Daniel takes a shot at a DIY animatronics project that involves a controller board, motors and controllers, sensors, and a host robot.

Mark Sullivan’s SERVO84 controller is the controller that I use for most of my RC servo projects. The SERVO84 was designed for a PIC16F84 IC servo controller application for robotics platforms. Sullivan’s code is highly optimized and can control up to eight RC servos using simple RS-232 commands. niobrara. html) and reverse engineering his code to build the board and see how he used the PIC16C84 I/O pins. This board has worked great for my RC Figure 2—Use this diagram to assemble the joystick controller board.
