(...) I built a project to do just what you want. In a tracked vehicle I have each track driven by a separate motor and each also drives one side of a 'differential' but in opposite directions. If both motors run exactly the same speed the sum is (...) (19 years ago, 2-Jan-07, to lugnet.robotics)

(...) The RCX sensor itself does not work without activating its LED. IN_TYPE_REFLECTION is the mode you should use with it (IN_TYPE_LIGHT_INACTIVE and IN_TYPE_LIGHT_ACTIVE are for NXT light sensor). As you noticed, the RCX light sensor has some (...) (19 years ago, 2-Jan-07, to lugnet.robotics.nxt)

Another observation. It seems that the IN_TYPE_LIGHT_INACTIVE is really not meant to be used with the RCX light sensor. There is very little sensitivity with this setting. The IN_TYPE_REFLECTION setting is much more sensitive. Too bad that we lost (...) (19 years ago, 2-Jan-07, to lugnet.robotics.nxt)

OK, I answered my own question. I just needed to set the sensor type to: IN_TYPE_LIGHT_INACTIVE for RCX light sensor with the LED ON IN_TYPE_REFLECTION for RCX light sensor with the LED OFF (19 years ago, 2-Jan-07, to lugnet.robotics.nxt)

Has anyone tried to control the RCX sensors with NBC? I have the converter cable and hooked up my RCX light sensor, but only got back readings of 53 (percent full scale). I used the NBC SetSensorLight command which should set the sensor to turn on (...) (19 years ago, 2-Jan-07, to lugnet.robotics.nxt)

I am not a NXT-G expert. I'm a programmer, so I moved to NBC pretty quickly. It's much easier for me to do things in a language than with graphics (not to mention the programs are 1/10 the size of NXT-G). Good Luck! David (19 years ago, 1-Jan-07, to lugnet.robotics.nxt)

(...) Just one rotation sensor. The differential gives you the difference (hence the name) of the two sides. If it's zero, you're driving straight. A positive rotation means you are turning one way, and negative is the other. It's not pseudocode, (...) (19 years ago, 31-Dec-06, to lugnet.robotics)

Does anyone have some RCX code to make a simple differential drive (2 independent motor/wheel combinations) with 2 rotation sensors drive straight. I'm sure it's been done many, many times before and I don't want to reinvent the wheel here. NQC or (...) (19 years ago, 31-Dec-06, to lugnet.robotics)
