How about <a href="http://www.seattlerobotics.org/encoder/200106/16csscnt.htm" title="16 Channel serial servo controller for robotic applications">16 of them</a> from a single serial connection?</p> <p><a href="http://www.makezine.com/blog/archive/2006/01/how_to_16_channel_serial_servo.html">Make Magazine&#8217;s Blog</a> dug up an interesting way to accomplish this. To update servo positions, a host sends a serial signal to an Amtel microcontroller. The Amtel remembers the positions and generates 16 different control signals. (One signal for each servo). The data is sent as follows:</p> <ul> <li>Byte1 = Sync (255)</li> <li>Byte2 = Servo# (0-15)</li> <li>Byte3 = Position (0-254)</li> </ul> <p>The host is either the serial port of a computer or a single pin of a master microcontroller. Therefore, a <a href="http://www.seattlerobotics.org/encoder/200106/16csscnt.htm#4." title="A Visual Basic application">PC program similar to his own</a> can be used to find the exact servo positions necessary for the application before the code is embedded on a microcontroller in the robot.</p> <p>Schematics and code are included. Other than that you are on your own.</p> Sat, 07 Jan 2006 07:23:00 -0800 urn:uuid:dc0acc69-cf1e-4880-a84f-fda77d61c36a Matthew http://superpositioned.com/articles/2006/01/07/16-channel-serial-servo-controller Cool Robots motors avr
