TOW3R 
By Thomas Madeya 



My contribution to #robotremix3 is TOW3R, named after the puzzle game “Tower of Hanoi”. If you don’t know the game you should learn about it first from 

I use the tires from both sets to create 3 “discs” of different diameter. TOW3R moves them around according to the rules of the game. Here are first photos I took to discuss the idea even before the actual build started

My first sketches for TOW3R already showed the key construction concepts: 
  • Turntable driven by one motor to rotate to three different positions 
  • Second motor to move the arm up/down 
  • Third motor to open/close the claw  
Image 
However, the ideas I had for the sensors did not turn out to be effective. The final model uses the color sensor to detect the position of the turntable, while the touch sensor detects when the arm reaches the up-most position. 
Here is a video to TOW3R performing the minimal number of moves to solve the “Tower of Hanoi” puzzle game. 



It took me several iterations of building and programming to get to the final model. Especially grabbing tires of different size with have more sensors and LEGO pieces at hand was a big challenge.

If you would like to learn more about how I solved that and several other challenges, please download the full story. Moreover, you can also download the EV3 project file.

Building instructions are not available yet, but are planned to be created soon.

Celebrating 25 Years of MINDSTORMS

By Asha Seshan - ROBOTMAK3R
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...

Celebrating MINDSTORMS with a Remix - Part 3

By Asha Seshan - ROBOTMAK3R
The ROBOTMAK3RS continued their celebration of the 25th Anniversary of MINDSTORMS through these Fall and Winter remix projects. Each ROBOTMAK3R was tasked with selecting one LEGO set of their choice and combining it with a MINDSTORMS set. Below are the five amazing models they came up with. Braill3 by Jerry Nicholls Braill3 is an EV3-based LEGO Braille bricks reader. This robot uses its fingertip, made from three touch switches, to read messages written using the LEGO Braille bricks and will speak out what it detected. If it sees a simple maths problem it will attempt to solve it and give the answer as well. To learn more about the process of creating this machine, read Jerry's blog . Braill3 can be viewed here . Set Review: The Braille Bricks set is well thought out. The ratios of the letters is suitable for general use and the addition of some punctuation and arithmetic operators is excellent. There is a card showing what bricks there are and their quantities, but no form of sort...

Ghostbusters R.T.V Remix

By Asha Seshan - ROBOTMAK3R
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...
