I have been using the Handyboard successfully for over 6 months. Recently I've decided to mount it on my robot base. After all the dust settled last night, I powered up the Handyboard. Since I put the batteries elsewhere on the robot, I put a keyed (...) (27 years ago, 9-Jul-97, to lugnet.robotics.handyboard)

(...) Well, the wheels are each driven independently by an internal motor. The rocker-bogie suspension is self-evident, but of course it works best if the wheel and motor sit out at the ends of the suspension. That means six motors. (...) I haven't (...)

just attack it with legos.... once you figure it out with legos, it's pretty easy... having looked at it my self... i would assume that only one of the wheels (per side) or all are driven, but the suspension system is very simplistic... infact, i (...)

I don't have a few million dollars to make one but there may be some useful (...) (27 years ago, 7-Jul-97, to lugnet.robotics.handyboard)

(...) This is the text-2-speech chip, but it doesn't include the allophone synthesizer (SP0256) so unless you have an allophone synthesizer this won't do you much good. --Chuck (27 years ago, 7-Jul-97, to lugnet.robotics.handyboard)

Has anyone heard when next years rules will be out for the Trinity firefighting contest? Are there going to be any major changes or are they going to stay about the same? Thanks. Keith Keith Soldavin kas219@email.psu.edu (URL) (27 years ago, 5-Jul-97, to lugnet.robotics.handyboard)

Jeff, JDR Microdevices sells the General Insturments CTS256AL2 chip (GI8642CAA) for ** $4.95 **. This is (I think) a slightly newer version of the same chip that Radio Shack used to sell.
