Like most of ’s projects, all the code and CAD files are open source and available on GitHub. Of course, this should be old news to anyone who has been doing embedded programming for a while, but it’s an excellent introduction for newcomers. Adafruit wrote an excellent tutorial on this method of multitasking, which based his code on. Instead, the millis function is used to keep track of the system clock in the main loop, which fires the position update commands at the specified intervals. The delay function is usually one of the first timing mechanisms that new Arduino programmers learn about, but it’s not suited for this application, especially when you’re controlling multiple servos simultaneously. The ratios can be changed to suit the desired speed. This gives the effect of the natural motion described above. The intermediate value is the sum of 95% of the current position, and 5% of the target position. To do this in Arduino/C code, a new intermediate position for the servo is specified for each main loop until it reaches the final position. When we move our heads to look at something around us, our neck muscles accelerate our head sharply in the chosen direction and then slows down gradually as it reaches its endpoint. Very little natural body movement happens at a constant speed, it’s always accelerating or decelerating. In the video after the break, demonstrates how to achieve natural motion with a simple animatronic head and a few extra lines of code. Hobby servos are cheap and popular for animatronics, but just letting it move at max speed isn’t particularly lifelike. Building an animatronic robot is one thing, but animating it in a lifelike fashion is a completely different challenge. ![]()
