| | Re: Several hardware questions.. Laser link Hardware expansion n' more
|
|
(...) In my system (one RCX and three Scouts), I had one 'master' and three 'slaves'. The rule was that no slave is allowed to talk unless first addressed by the master. I've finally gotten around to writing up this setup and putting it on the web. (...) (23 years ago, 9-Jul-02, to lugnet.robotics)

| | Re: optical mouse chips as vision sensors?
|
|
(...) Yes - mathematically, you could still do it with the mouse sensor off to the side of the robot (but not with it dead center between the wheels) - however the sensitivity of the chip to small lateral movements probably wouldn't be enough to (...) (23 years ago, 9-Jul-02, to lugnet.robotics)

| | Re: optical mouse chips as vision sensors?
|
|
(...) The mouse's camera chip tells you how fast the beast is moving forwards/backwards and how fast left/right - as two separate sets of numbers. If you mounted it on a boom (say) six inches ahead of the wheels of a typical two-wheel-plus-caster (...) (23 years ago, 9-Jul-02, to lugnet.robotics)

| | Re: Navigation using landmarks (Was: Re: lasers and RCX)
|
|
(...) Yes - I was thinking of some kind of spring-loaded arm pressing the mouse's underside against the ground. (...) For a Killough platform, you have a fundamental problem. That type of drive has three degrees of freedom (well - it *ought* to have (...) (23 years ago, 9-Jul-02, to lugnet.robotics)

| | Re: optical mouse chips as vision sensors?

Nevermind... I was assuming it would be mounted to the left or right of center (thus the rotation would still show up as forward or reverse). After thinking about it a moment, it occurs to me that by mounting the sensor in front of or behind the (...) (23 years ago, 9-Jul-02, to lugnet.robotics)

| | Re: optical mouse chips as vision sensors?
|
|
(...) Hmmm... I don't see how that would work. How would a single sensor be able to differentiate between rotational movement and straight forward & back movement? I suppose you would be able to guess since you would know what state the robot was in (...) (23 years ago, 9-Jul-02, to lugnet.robotics)

Hi Ralph, I don't know if you remember, but I had problems with SAVE-SYSTEM (see msg# 508)... until now! Just to let you know, with pbForth V2.1.5 and (more likely) GUI V2.1.3, it works fine! Thanks Mario (...) (23 years ago, 9-Jul-02, to lugnet.robotics.rcx, lugnet.robotics.rcx.pbforth, lugnet.robotics.rcx.legos)

Hi! all, I've posted a similar topic before titled "control multiple mindstorms robots using 1 IR tower", so I'd also like to get more info. about this related issue.If someone is generous to open his coding, I'll greatly apprecidate it! Hope (...) (23 years ago, 8-Jul-02, to lugnet.robotics.rcx.java)
