| | IR communications related questions

| I've been working with LegOS for a while but am quite frustrated. I have been unable to get lnp working and am thus unable to to communicate with the host. It is all overkill for me since I merely want to capture some simple data. I am switching (...) (24 years ago, 1-May-00, to lugnet.robotics.rcx.pbforth)

| | Another way to avoid Float

| For the navigation of my robot, I do not plan to use float or trig function. I will use long integer (32bits). the high 16 bit are the true integer value. the low 16 bits are 1/65535 value. let say 1 = 0x00010000 2 = 0x00020000 2.5 = 0x00028000 2.25 (...)

We are working with a image recognition system on a Linux machine that computes the position of robots and sends an integrity packet of 18bytes (...)

(Standard light sensors see them just fine.) However, battery life is quite short (approx. (...) (20 years ago, 23-Mar-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

| | IR Tower - Laptop Comms
|
| Maybe not exactly Lego, but..... Has anyone any thoughts about using the IR Tower to communicate with a Laptop's built in IR transceiver? Maybe set it up using Direct Cable Connection?? If I should ask this elsewhere, please put me straight :) (25 years ago, 4-Apr-00, to lugnet.robotics.rcx)

| | Re: how detect other RCX robots with light sensors?
|
| Assuming both RCXs are facing each other, this can be done by using the IR transmitter of the RCX on the detected robot, and a forward pointing light sensor on the detecting robot. Set one robot (the detected robot) to send out constant IR messages. (...) (24 years ago, 15-Apr-00, to lugnet.robotics.rcx)
