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)

All- Ok, I'll re-phrase..... Does anyone have the name and supplier of a substitute (for the Sharp IS1U60 infrared demodulator) that they have gotten to work reliably? Thanks. Steve (...) (26 years ago, 8-Jan-99, to lugnet.robotics.handyboard)

| | A newbie question
|
|
I want to program my HB so that my robot will be able to navigate around obstacles. The navigation area is a rectangular area boarded by a silver duct tape. My robot shall not touch the tape. Does anyone have any idea of how I can implement this? (...) (26 years ago, 8-Jan-99, to lugnet.robotics.handyboard)

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)

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)

I previously posted information on the list about the controller and chassis that I am intending on using for my six legged walker so checking the archives may be useful. I am using an MSCC11 from Novasoft as a servo controller, I don't believe the (...) (26 years ago, 8-Jan-99, to lugnet.robotics.handyboard)

Hi all Iam thinking about making a six legged walking robot using servos and wondered if anybody has already built one. I want to use two servos per leg one for lifting and another for the sweeping action so giving 12 in total. One thing i want to (...) (26 years ago, 8-Jan-99, to lugnet.robotics.handyboard)

You can do this in IC 3.2, perhaps not in the freeware version. -----Original Message----- From: Christopher Prosser <christopherprosser@yahoo.com> To: FEDSANTE@tin.it <FEDSANTE@tin.it>; handyboard@media.mit.edu <handyboard@media.mit.edu> Date: (...)
