 | | Re: Obstacle detection : infrared sensor ??
|
| (...) We have done this in C using LegOS (it is much easier to get it off the ground in nqc). The principle is simple: * Attach the light sensor in front of the brick, close to the IR tranceiver. preferably in a low position, since you want to (...)

| | Re: Micro-Switches, Mux
|
| Knowing the resistor inside the RCX is 10 kOhm, you should use a different resistor for each switch, the first resistor should be 10 kOhm, the second 30 kOhm, third 70 kOhm, fourth 150 kOhm, this will divide the 5V range in nearly evenly spaced (...)

| | Re: Revisions to RcxCC
|
| hi John, Great idea, (for RCXcc is a very good application, even my children can write programs with it) I just had the same idea, but my time is limited. I've need some more ideas, here are some of mine ideas (and bugs), I wanted to implement: - (...) (24 years ago, 4-Apr-01, to lugnet.robotics.rcx.nqc)

| | Re: Blocking The Lego Remote?
|
| Hi Stephen, you will not have success with this approach, because the LEGO firmware has no collision detection (especially no collision avoidance !) for their IR protocol. So if you're using more than 2 IR devices with LEGO firmware you will receive (...) (23 years ago, 27-Apr-01, to lugnet.robotics.rcx.nqc)

| | Blocking The Lego Remote?
|
| Problem: I Have 2 Lego RCX's 1 Lego Scout and a Lego Remote. I want to build and operate 2 robots at the same time. One robot out of the Scout being remotely controlled by the Lego IR Remote and the Other with 1 RCX being controlled remotely via IR (...) (23 years ago, 26-Apr-01, to lugnet.robotics.rcx.nqc)

| | Re: My RCX doesn't work!

| I would replace the battery in the tower again. Watch the green light on the tower as you boot the computer. It should turn on once for a short time and then for a longer time as the boot sequence is completed. Check the cable connections at both (...) (24 years ago, 23-Feb-01, to lugnet.robotics.rcx)

| | Re: Anyone using Mac beige G3
|
| (...) I've had similar problems with a CyberMaster. It seems that CyberMaster Tower is powered by the serial interface (at least it is switched on by this power). On PC, the DTR line is switched high (12 V), and the CTS line is switched low (-12V). (...) (24 years ago, 1-Feb-01, to lugnet.robotics.rcx.nqc)

| | Re: sending variables betwen rcx's?
|
| Hi Adam, if I understand your problem correctly, you want to transmit a sensor value from one RCX to another RCX which will work with that value. Now, if the 2 RCXs can "see" each other than simply use the Message statement. If not, you should take (...) (24 years ago, 26-Mar-01, to lugnet.robotics.rcx.nqc)

Now I have converted wav file to mono data sampled at 11025Hz (can be changed) and sample range is 0-255 as below: 144, 150, 154, 156, 160, 159, 154, 149, 143, 134, 128, 120, 110, 103, 97, 93, 91, 93, 96, 102, 110, 120, 127, 138, 149, 156, (...)

| | Re: Robot navigation - barcode stations?

| I think it's an excellent idea... I saw the barcode system being explained some years ago and I still think it can be the most accurate. One thing that's different in the system I saw was that there were no LED's used (not needed...) and it would (...) (24 years ago, 29-Mar-01, to lugnet.robotics.rcx)

| Ok, this is called a "Slip Gear" or "Torque Gear" It is used to prevent over rotation by means of an internal clutch, the 2.5 - 5.0 NCM I belive means the range of operable force applied before the clutch disengages. Nano Centemeter of force. In (...) (24 years ago, 3-Apr-01, to lugnet.robotics.rcx)
