| | | Has anyone tried to use wireless networking to control a legorobot? IP programming in VB is easy and I was thinking of making a robot which uses the RCX as its medulla and a stripped down laptop with a PCMCIA Ethernet adapter as the cerebrum. The (...)

| | | | | I've been working on this exact same thing. To that end I bought a pair of wireless ethernet cards from Diamond and I plan to have the "laptop" which in my case is a PC/104 Single board computer, run Personal Webserver thereby contoling both the Cam (...)

| | | | | | Hi! How are you interfacing the RCX with the network card? It doesn't seem like a trivial thing to do... /Vlad (25 years ago, 22-Nov-99, to lugnet.robotics)

| | | | | | I'm not : ) The laptop gets the ethernet card and it in turn interfaces with the RCX... Vlad Dumitrescu wrote in message ... (...) a (...) (25 years ago, 23-Nov-99, to lugnet.robotics)

| | | | | | Vlad, You're not missing anything at all. You are correct that the communication between the RCX and the laptop isn't faster. But the communication to the now more powerful (because of the laptop) robot is musch faster (1MB/s Ethernet instead of (...) (25 years ago, 25-Nov-99, to lugnet.robotics)

I still am not seeing how this is going to be faster than if the RCX was communicating directly with a stationary PC... the only improvement is that the range of the robot is better (if the laptop sits on (...)

| | | | | | Vlad, Bingo. I want to be able to control the whole thing via a web page on the 'net and see images from the quickcam that's mounted on the beast. Much faster to transmit jpgs over wireless ethernet than over 2400 baud IR. BTW the lap top is a piece (...) (25 years ago, 26-Nov-99, to lugnet.robotics)

|
| | | | | | You can transmit pictures over the IR link? If you could do this, even if it was slow, then that would open up a whole new range of possibilities. Andy (25 years ago, 26-Nov-99, to lugnet.robotics)

| | | | Matt, I have built a lego robot controlled by a PC, using an IR link to communicate commands. It used the same IR technology as Mindstorms, but had an omni-directional IR link on the robot. The problem is link speed. For reliable communication, you (...) (25 years ago, 21-Nov-99, to lugnet.robotics)
