 | | Re: First LEGO League competition in Cincinnati Ohio
|
| As a head referee for 3 of these contests this year, and many in the past, I have to second Jeff's recommendation to volunteer for these. You can find them on www.legoleague.org . Better yet, form a team and be a coach for next year. Believe me, (...) (22 years ago, 22-Nov-02, to lugnet.robotics)

| | Re: Erroded axles
|
| I read this in your [fantastic, best LEGO robot book ever] book as well, but don't understand it. The snapping action of the links doesn't open in the direction they would be loaded in use, so how do they come apart? Did you try them in both (...)

| Don't cut anything. In this exact same situation, I use a pair of medium pulley-wheels, mated together with half-pins through the six outer holes (3 in one direction, 3 in the other). There is very little grip area, but because you are right at the (...) (22 years ago, 17-May-02, to lugnet.robotics)

| | Re: user created programs
|
| Yes, your new page is good and what we need. But I immediately have a question: It seems there are two pairs of canted receptors, two at front, and two at about mid-board. This implies there is some inherent directional sensing? I assume at least (...) (22 years ago, 8-Jan-03, to lugnet.robotics.spybotics)

| | Re: Solar panels, capacitor
|
| Thanks for your response, but it really didn't address my questions. 1. How are these things supposed to be connected to an RCX? 2. Assuming that I could get power to it, would the RCX run with a solar panel (300ma) if I didn't connect any motors? I (...) (23 years ago, 13-Sep-01, to lugnet.robotics)

| I thought the previews were "canned". I wouldn't mind a similar ability to can sub-model images. In other words, put the burden of updating on the user. Not having any way to get a preview image is pretty frustrating, especially if you do a lot of (...) (25 years ago, 20-Dec-99, to lugnet.cad.mlcad)

| | Re: First Lego League Software

| I agree that it is a problem. In fact, I didn't know Robolab could use variables. So it was unfair, though not hugely so. This is something FLL needs to address, because the lack of variables is really a big flaw, and very hard to explain to the (...) (25 years ago, 22-Dec-99, to lugnet.robotics)

| I bought a used batch of LEGO the other day, and it turned out to contain a large number of clones marked Tyco. Since I don't wnat these contaminating my LEGO, I plan to get rid of them. Is there an aftermarket for these? I had never heard of Tyco (...) (23 years ago, 29-Oct-01, to lugnet.off-topic.clone-brands)

| | Camera IR and the RCX

| I am a coach of a bunch of FLL kids, and have heard tournament organizers say "Auto-focus cameras may not be used". How real is this? Seems to me, the only thing that could affect an RCX that was not programmed to listen for IR messages is something (...) (23 years ago, 20-Nov-01, to lugnet.robotics)

| | Re: Wholesale prices on RIS

| The price control on RIS is very high. I doubt you will find it discounted anywhere until the next version comes out. Some RIS 2.0 were discounted before xmas, but most were RIS 1.5. Believe me, if there was a good way to get them at a low price, it (...) (23 years ago, 28-Mar-02, to lugnet.lego.direct)

| | Re: Camera IR and the RCX

| I understand that even when it isn't programmed to do so, the IR subsystem in the RCX is operational. Otherwise, the remote wouldn't work. So we know it is "listening", even though the kids programs in these robots aren't programmed to listen for (...) (23 years ago, 20-Nov-01, to lugnet.robotics)

| | Re: Friction on Rotation Sensor

| Are you sure it is the sensor itself? We have found that the axis is often "off" a bit from canonical LEGO spacing, and if built into a structure, binds quite a bit. But if you assemble it so that the body (blue) of the sensor can "float" with (...) (22 years ago, 26-Jun-02, to lugnet.robotics)
