LMR 4 years birthday party

Hello, and congratiolations to all of us :D

LMR 4 years birthday will be officially celebrated in the time from Saturday January 28th to Friday February 3th 2012.

It's almost a tradition that creative souls make some form of artwork to celebrate - and if you should do so this year, please either post it here, or link to it from here :)

Also, make sure to keep an eye on the front page, where announcements and stuff will be posted during the celebration :)

LMR Job database


Thanks for all the feedback :) We are considering everything while working on LMRv4 - and for now this is off the top menu on this "old" site.

Hi guys,

I am planning considering to make a new top menu item: Jobs (Well, I made it, just to see how it would look up there ;)

LMR ROS platform

What is ROS

Here is a list of robots running ROS

I think it would be great if we could make a minimalistic, cheap, easy reproducable, simple robot running on ROS. Something to get people started with ROS, as the isolated and primary goal.

If any one out there is up for that challenge, let me know, and I'll support by such things as getting it in the menus of LMR, perhaps make videos about it, and get it on the official ROS pages, maybe turn it into a "start here" tutorial etc.

Quick resistor question: 3,3 V from 4,07

I am not too proud to ask:

I have a LiPo supplying nominal 3,7V -- 4,07 at the moment, possibly fully charged.

I also have a gyro sensor that ask for 3,3 V - and I'd hate to fry it.

I really, really cannot understand the law of Ohm, so I am asking, can any one tell me what to throw in there?

Thanks :)


(Oh, and any tips on brown out detection would be appreciated; I'd hate to discharge my LiPo, but am trying to keep this simple, becaue that is my style ;) - Any smart tips on making sure it will not go too low?)


Here's a guy who would like a little spam

Santosh:  let me know if you need SEO services

How would you register the sligtest touch?



I have an idea for a really fantastic little project (IMO :) I'll show it later, but I have run into a little challenge that I did not see when I woke up in the middle of the night with the overal concept crystal clear in my head.

I need a "probe" - a small thin stick - like a long fat needle - to move forward towards an object, and with none, or only a slight touch, register when it touch the object.

Hi guys, have you seen the new picaxe.com?

I am proud to say that I was on the sideline when it was made :D

Let me know what you think, all comments are very welcome, I'll pass them on :)

Can you offer too many amps?

I have this multicopter. it is a flying robot, with one huge, powerful LiPo underneath.

I say it again, it is huge, and it can pull a car with all the amps and burst-c's that I dont understand.

Building the thing was terribly nerve wrecking - though it mostly was made from other peoples semi-premade parts. Because; I have extremely delicate 3Volts electronics side by side next to stuff that needs cables fat as a thumb, because of all the juice (in lack of better words) they have to let through.

Now, my question is this:
