Re: NXT / problem with 2 colour sensors

Can you try posting a screenshot of the code? It's been a while since I've used nxt-g but there is also something called "pack and go" that lets you bundle the files so you can share them (...as an attachment?).

Re: NXT / problem with 2 colour sensors

Can you provide some specifics about the type of color sensors you are using and the code that fails?

Cheers,

Re: NXT PROBLEM

I have to agree with doc. This sounds like schoolwork. It won't help you learn if someone does the work for you. I suggest the NXC tutorial and getting some hands-on time with an NXT. Also, try writing pseudo code (look it up if you need to) and get the proper logic flow. I think you might get more ...

Re: New NXT Sensors and interfaces

How about an x10 interface and some home automation widgets? I haven't researched it at all, so I'm not sure what's feasible. Could be a good challenge and some fun, tho.

Re: Need help Urgently (NXT COLOR SENSOR)

I for one am curious what you found and what code you fixed to make things work. :D If your robot is still missing colors (or thinks it's seeing them at times when it should not), you might need to add some noise filtering or averaging to the sensor data. See the thread below for an interesting disc...

Re: Need help Urgently (NXT COLOR SENSOR)

Out of interest in the project you are doing, I was just wondering if you could list the steps/goals of the program in simple terms that are not language/syntax specific. Just to confirm, you are using the Lego Color Sensor (the one that comes in the NXT 2.0 kit), right? I think you're right - the v...

Re: Need help Urgently (NXT COLOR SENSOR)

Did you get this solved? If not, can you post pseudo-code for what you are trying to do?

Re: NXC: 4 US sensors at 1 HT SensorMux in single shot mode?

Hi Doc, I had a thought about a work-around for your US sensor/mux problem... At the cost of a motor and motor port, you could rotate a single US sensor in a +/- 180 deg sweep back and forth to get full radius 'look around'. You could even use a sensor mux, since no interference means you don't need...

Re: what should i add?

how about adding some sensors on a swivel head, as in the "Explorer"? http://www.nxtprograms.com/NXT2/explorer/index.html I made a few variations on the Explorer theme; one had a light sensor on a motor-driven swivel such that it would scan about 60 deg each side off-center. I wrote progra...
