After Ian and I did all the technical building creating our Robot Arms, it was time to build control cabins on top of the arms! I had fun and made not only a control cabin, but I figured all good robot arm's have a Castle at the back, right? (7 (...) (17 years ago, 28-Jan-08, to lugnet.technic, FTX)

I have two 8735 sets and a Mindstorms set, so for power I have an RCX and two battery boxes. I've had 3 motors for a good 5 years now, so I ordered a second 8735 set and it arrived today. :) Any project ideas? Cool MOCs out there I could replicate? (...) (17 years ago, 27-Jan-08, to lugnet.technic)

(...) Very good. Have you done experiments to map the power level settings to RPM? I am guessing that each of the 7 steps sets literally a power level (PWM width) and not a speed. Have you done experiments under load to see what happens to the speed (...) (17 years ago, 27-Jan-08, to lugnet.technic, lugnet.trains, lugnet.robotics, FTX)

(...) Could it be that the long range mode of IR is not set (I saw no reference to range setting in your source, and I don't know the default state). Despite the difference in carrier frequency, the RCX 1.0 and RCX2.0 are able to dialog albeit with (...) (17 years ago, 27-Jan-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics)

(...) I just tried the new commands with a home-made NXT-controlled IR remote. I was able to get them to work without a problem. I verified the single-output PWM mode, which starts a motor at a given power level, in which it stays indefinitely (...)

(...) i have not really spent a lot of time trying to figure these modes out. i was more concerned with getting the PWM to work correctly. i'm going to spend more time testing this and will let you know. bob (17 years ago, 26-Jan-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics, FTX)

(...) Glad it worked for you and thanks for the heads up on the RCX 2.0 problems. i don't have a 2.0 RCX to play with so i'm not sure if it is a timing issue that can be resolved or what. i was very excited the first time i got my RCX to talk to the (...)

Well this was just a quickly hacked out example program to show how to use the library function that i wrote. i realized at the time that the PWM started out at fastest and went to slowest but i had run out of steam and never really got back (...)

(...) On page 13 it shows the transmit time slots. Giving each channel a unique stagger for repeats certainly helps avoid collisions, but I'm confused as to why they have a transmit hold off. If person A is on channel 1, and person B is on channel (...) (17 years ago, 26-Jan-08, to lugnet.technic, FTX)
