LDD Building Instruction samples and .lxf file

In a post earlier this year, I wrote about a small bot I built that would be able to participate in RoboCup Jr. This IRBot and all its parts had to fit in a circle with an 18cm diameter and could not exceed a height of 22cm. The IRSeeker sensor would detect the IR ball used in the competition and the Compass sensor could be used to give the robot a sense of direction and better comprehension of the playing field (where is the competition's goal relative to my position and orientation? where is my goal?)

The robot I built used HiTechnic's IRSeeker sensor and the Compass sensor. Now, LDD does not yet have HiTechnic's sensors included in the palettes, but that didn't stop me from creating some building instructions for it with LDD. You'll just have to substitute the Compass and IRSeeker for the Light and Sound sensors shown in the steps.

You can download the (zipped) .lxf file here.

And you can download the 3MB zipped file containing 28 PNG images containing the steps to build this robot here.

The robot may not be that impressive, but consider that it took me less than 30 minutes to build it using LDD and another 30 minutes to take and crop screenshots of the 28 building steps. In about 1 hour, I've been able to not only design a simple bot in LDD but also create fully functional building instructions for it that can be shared with anyone who wants to build it... modify it... add on to it...

I'm also providing these building instructions to show you how easy it is to create them for places like NXTLOG and other websites. Instead of just a few photos, try building your robot in LDD, take some screen captures using the Building Instruction Player (a tool in LDD) and uploading the images to NXTLOG or other and let others try out your design.

Have fun.

Celebrating 25 Years of MINDSTORMS

In celebration of the 25th Anniversary of MINDSTORMS, we take a trip through history. Please also visit ROBOTMAK3RS Community every week as we highlight different projects all through 2023 in celebration of the anniversary. Some of the early history is based on the content shared by Coder Shah in our MINDSTORMS EV3 Community Group . Some of the text and links may have been edited from his original posts for consistency and clarity. 1984 - Kjeld Kirk Kristiansen watched a TV program called "Talking Turtle," where MIT professor Seymour Papert demonstrated how children could control robot "turtles" using LOGO, a programming language he developed. 1988 - The collaboration between MIT and LEGO resulted in LEGO TC Logo in 1988, which allowed students to control LEGO models using computer commands. The video shows Papert demonstrating TC Logo. 1990 - LEGO TC Logo was hampered since the robots you built had to be tethered to a personal computer. LEGO and MIT...

ROBOTMAK3RS Review: LEGO River Steamboat

I thought the LEGO River Steamboat would be an interesting set for a ROBOTMAK3R review for a few reasons. First, the LEGO designer of the model is Marina Stampoli, a long-time collaborator of the late ROBOTMAK3R Vassilis Chryssanthakopoulo s. From earlier collaborations with Vassilis, I knew Marina was incredibly talented, with an eye for aesthetics and functionality. Her background in architecture is particularly useful for her relatively new position at LEGO. Her other sets include the Magic of Disney (21352), Message Board (41839), and Red London Telephone Box (21347). Second, watching Marina's reveal video and reading her designer interview made this set even more tempting to build. The gearing mechanisms running through the model gave way to many opportunities for automation using LEGO robotics elements. Since ROBOTMAK3RS is all about adding interactivity and automation to LEGO brick, I thought it would be fun to see where and how LEGO robotics could be added to this s...

Ghostbusters R.T.V Remix

Nino Guba is from Torrance, California, USA. He played with LEGO as a kid, but growing up in the Philippines, it wasn’t something he had easy access to. He only got reintroduced to LEGO when he moved to the US and had kids of his own. When his sons were younger, they received LEGO sets as gifts, but as they grew older, the sets got put into storage as their interest faded. Fast forward a few years, he started coming up with his own product ideas and thought about how he could quickly prototype them. That’s when he discovered LEGO MINDSTORMS—and was hooked! He raided his kids’ old collection, got everything organized, and now he's designing and building his own creations, blending his coding skills with LEGO robotics to bring ideas to life. Tell us about your Ghostbusters Remote Trap Vehicle (R.T.V) project. This project is a LEGO Technic adaptation of the Ghostbusters R.T.V.—a ghost trap converted into a remote-controlled vehicle. Its companion build is a prop replica of the Futaba...
