Greetings all, I have been programming lately using the recently released dual servo routines. I have noticed that if I enable both servos and simply send each of them a pulse (servo_a7(or 5)_pulse=3040 for example) they respond faitfully but then (...)

(...) there 's one little mistake here.. you do not only need the servo.c file, but also the servo.icb file...So first you have to load the servo.icb file an then the servo.c file to get the thing working... Now you can use the servo commands as (...) (28 years ago, 15-Jan-97, to lugnet.robotics.handyboard)

I'm kind of stuck, and hopefully someone can tell me what I'm doing wrong.

Can some give me a suggestion as to what kind of IR sensors would be good to use in conjunction with the Handboard on a mobile robot. I remember seeing some info on Sharp IR modules...and if I'm not mistaken, the posting mentioned that these IR (...) (28 years ago, 15-Jan-97, to lugnet.robotics.handyboard)

Tom, With regards to your writing the program that compared two sensors...may I ask what specific sensors were you using? or had in mind?? Jim Tegarden (28 years ago, 15-Jan-97, to lugnet.robotics.handyboard)

I located a 9.6 volt 700 or 900 mah battery pack at Radio Shack and the one on the parts list is just 500 mah. My question is, will the charging circuit work ok with either of the above battery packs from Radio Shack? Thanks Bill Rose (28 years ago, 15-Jan-97, to lugnet.robotics.handyboard)

| | Re: Ports on Windows NT
|
|
Dear Chris, The reason that the downloaders don't work with NT is probably due to the fact that NT has a hardware abstraction layer, and requires special code to access it. I don't think either HBDL or IC has this code. As far as the Win 3.1 goes, (...) (28 years ago, 15-Jan-97, to lugnet.robotics.handyboard)

It is not completely wacky, but there are issues. For example most audio amplifiers aren't rated for DC operation (that having their output stay at one level permanently) You can fix this by rectifying the output of the amplifier and providing a DC (...)
