I put together the HB shortly after it first became available. This is key because it worked-downloading and all. I put it down for a year because of family problems but all that time left it plugged in because of the Ni-cad. I feel that should (...) (26 years ago, 11-Jan-99, to lugnet.robotics.handyboard)

| | Expansion board motor outs???
|

I just wanted to verify something before I went and purchased the expansion board. Are the HB's motor outputs still available when using the expansion board. It is unclear in the doc. Thanks, Aaron (26 years ago, 11-Jan-99, to lugnet.robotics.handyboard)

| | Failure to Boot Up

I recently purchased the Handy Board 1.2 and am running the HC11E1FN. I also purchased the IC compiler from Newton Research Labs. Everything worked great. I hooked up a hobby servo to PA7 and it ran well with the supplied c routines. However, after (...) (26 years ago, 9-Jan-99, to lugnet.robotics.handyboard)

if your robot is not allowed to even partially cross the duct tape, you must have an additional inner marking that the robot can see so it knows it's near the "danger zone" and can change direction. f. (...) (26 years ago, 9-Jan-99, to lugnet.robotics.handyboard)

| | Re: hexipod walker
|
|
Timing 12 servos with the HB could be done. So far we are using 8 servos which don't use much cpu resources at all. But 1 compare output can only time 8 servos because of the servos timing requierments without using a lot of cpu time. So a second (...) (26 years ago, 8-Jan-99, to lugnet.robotics.handyboard)

| | RE: hexipod walker
|
|
The only problem with using individual servo control is speed, the time it takes to move 12 servos by individual commands is rather long. This has the effect of slowing the walker down considerably. A dedicated controller such as the MSCC11 that I (...) (26 years ago, 8-Jan-99, to lugnet.robotics.handyboard)

| | RE: hexipod walker
|
|
I believe the best thing to do is use separte controlers (e.g. PICs) to control the specific motions of the servo's. This will allow you to have more control over the HB. There are several places on the web (e.g. (URL) where you can find info on (...) (26 years ago, 8-Jan-99, to lugnet.robotics.handyboard)
