Lately, I have noticed an increasing amount of spam on this list. I belong to 16 different robotics related lists and none of the others get spammed this bad....
hi jeff, thanks i was hoping for a faster scope but i don't know, you can check on the price and availability, ralph ... i ... series scopes. ... remember the ...
John and the list members: Yes, I agree, it is now time to change the posting rules. I'll change the rules such that only members may post messages. I've...
... John: Maybe you can post a lists of these other robotics related lists you belong to. Other members may not know about some of them. Thanks, Pete...
Pete, These are some of the Yahoo lists I belong to: 68332ABB - Related to 68332 microprocessor FireFightingRobots - Trinity Firefighting robot list handyboard...
Alex, I just bought yet another motor off of ebay. So I have enough hardware, in pieces, to open a door. Now I need to write the software. My bot knows how...
Scott, I don't think my software would be easily modified for your task. Mine assumes it is already near the center of the road (or door) and just looks for...
Scott, Once you have localized the doorknob and turned it, how do you know whether to push or pull on the knob to get the door to open? Jeff. ... -- Jeff...

Hi Scott, I have been using the CMUCam http://www-2.cs.cmu.edu/~cmucam/ for simple robot vision and I think that it has a few nice features that you could use ...
Thanks Alex and Bryan! Jeff, you're right, the bot won't be able to tell whether to push or pull. So I will have to hard code that in. Also meaning that the...
No, I meant to look for the vertical dark lines by searching the webcam image. A simple edge detection algorithm would likely find either the crack between...
Scott, just an idea - you mentioned that your knobs are in 'gold' color. It sounds to me like you have metal knobs. So, the task can be transformed from ...

This is a good idea. Forget vision and detect the metal doorknob and the metal door hinge. The hinge location will help the robot decide which way the door...
For a small metal detector - I would consider a wall stud sensor (for finding nails inside walls). I remember seeing on the internet that someone had taken...
Scott, The simplest metal detector would be two small spring pads with one being connected to a digital in port on your microprocessor and a pull down resistor...

Scott, There is simpler solution to letting robot in. Instead of making robot, which opens the door, you can make the door, which opens when robot approaches...
Hi Scott. ... This does sound interesting. I really had not given much thought to Java for robotics. My impression was that since it runs on a virtual...

Jeff, I'm not a Java expert, so I don't know about the performance issues. Maybe I should try emailing Sun? I do know that multi-threading is built into Java...
I was hoping to post the upcoming Robot Sumo Wresting Competition at the <http://www.casciencectr.org>California Science Center, but it has been cancelled for...
You've probably heard of Acroname, they sell hobbyist robots and parts. They have a new robot "Garcia" that comes assembled. The idea is that you spend your...
Scott, Alex has mentioned Acroname however The MarkIII Robot Store has them much cheaper. $8.25 for a GP2D12 sensor. I have dealt with them numerous times in...
