I have been playing with my Handyboard (from Digital), and am still waiting on the little mobile platform I decided to start out on. (My retired father-in-law is a mechanical creator, & is PC literate, so I am planning on getting him involved after (...) (28 years ago, 6-Aug-96, to lugnet.robotics.handyboard)

| | Manipulator Question
|
|
Hello, Could someone please tell me if there is a (not-so-expensive) manipulator which can be driven by HB? I'm quite interested in driving the manipulator to draw a text on a sheet of paper. Or, do I have to look for a plotter instead? I'm using (...) (28 years ago, 6-Aug-96, to lugnet.robotics.handyboard)

I've got the sonar going - it's neat for looks, but I'm still working on putting enough code behind it to make it fast and functional - servos (...)

Hi Patrick, I assume that you're using the stock S4282/LED setup? It is possible to get better range using a slightly different configuration. The range is largely a function of the the LEDs intensity. Since the S4282 modulates the LED at 1/16th (...) (28 years ago, 6-Aug-96, to lugnet.robotics.handyboard)

Hi Jeff, (...) There are no schematics, per se, but there are directions in the cher/.../kent directory. The following excerpt is from the readme file there. It contains the information you need to attach the ranging module to the Handy Board. Hope (...) (28 years ago, 5-Aug-96, to lugnet.robotics.handyboard)

And if so are there connections for it (Port A7) on the Handy Board (besides connecting it right to the HC11)? I have a pulse train signal coming from (...)

Hello everyone!

I am getting about 335 (...) (28 years ago, 1-Aug-96, to lugnet.robotics.handyboard)

| | Re: sonar sensors

Hi Sriram, To answer your question succinctly, yes you can use the sonar modules on the Handy Board without the expansion board. Infact, Kent Farnsworth has written up exactly how to do it with your existing HB. Instructions, code, etc. can be found (...) (28 years ago, 31-Jul-96, to lugnet.robotics.handyboard)

Two comments for Garth (and others doing this) #1) You have 2 phase, bipolar *STEPPER* motors, not "servo" motors. The difference is quite significant if you were expecting a servo motor. A stepper motor has a coils positioned around the motor shaft (...) (28 years ago, 31-Jul-96, to lugnet.robotics.handyboard)
