Hi Doug: I built a 12-servomotor walking robot using two SSCs - their interface with the HandyBoard is well documented, and ICB drivers are available on the webpage. I communicate with two SSCs (www.seetron.com) via one serial line connected to PA7 (...) (27 years ago, 16-Apr-99, to lugnet.robotics.handyboard)

Hello, I am planning to build a robot based on the Lynxmotion Hexapod II and Big Grip kits. There will be 12 servos for lego control, 2 servos for the manipulator, and 2 more for a camera pan/tilt unit. Everything appears fairly straightforward, (...)

I'm using Kent Farnsworth's older sonar driver code that is designed for the motor driver output ports (U11). The (...) (27 years ago, 16-Apr-99, to lugnet.robotics.handyboard)

(...) I don't have the Ferrettronics chip datasheet in front of me but some off the cuff calculations: 2400 bps/10 bits per byte=240 bytes per second each servo will require at least 2 bytes (servo # and position) 16 servos * 2 = 32 bytes for each (...)

We just finished using the same comm. boards for our senior project, so maybe I can help a little. (...) One interesting phenomenon we noticed was that we received random noise at the receiver when the transmitter wasn't on. However, when the (...)
