Cute Lego Felt Tip Printer

A friend forwarded this to me. Cool application of Lego to make a printer. The video author's comment on YouTube:

"Lego felt tip 110" printer connected to an Apple Mac.  This is not a kit you can buy and does not use MindStorms. I designed/built/coded it all from scratch including analog motor electronics, sensors and printer driver, the USB interface uses a "wiring" board.

Once again, this is not my work. I'm just posting something I found cool.

It uses a DSP board for the image processing and decision making, then uses different colour LEDs to indicate the NXT robot which key it should press.

Mindstorm NXT 2.0 N900 - Twitter-controlled Robot

"Moooo" Rare Swiss Cow Project has begun

Following on from the Laser Experiments i have decided to attach it to some kind of walking Robot.

I am now a avid fan of Theo Jansen -  after rik brought him to light in his Blog.

So far i have Prototyped two pairs of "Theo" legs using "MindStorms" as an experimental base.

It worked better than i could have imagined - these legs go like a Cow on its way to the milking parlour.........

Only problem now is what  medium shall i use to make the final version.....

I haven't posted a Lego robot or a line follower, so I thought I'd do both together. Line followers have been done to death. I've blown the dust off my Lego RCX. … Read more

My UAV ideas

I've been reading this site for the past week or so, and it has really inspired me to get more into robotics. I've had a couple of ideas for robots that I want to make in the future, I am going to start of with fritsl's starting robot, but I just wanted to share some of my future ideas to see what you guys think.

Labyrinth Line Follower Advice Please

I wish to build an autonomous robot capable of navigating a human sized labyrinth at our local senior center.  I need to make it mostly from VEX parts programmed in RobotC.
