Robot Remix #5 - FOOD TRUCK

By Asha Seshan - ROBOTMAK3R

Food Truck by Young-jun YI

Robot Remixes offer new possibilities for your MINDSTORMS set. The Food Truck Robot Remix is a combination of the LEGO MINDSTORMS 31313 set and LEGO Technic 42076 set. It was created by Young-jun YI, a ROBOTMAKER from Korea.

Using MINDSTORMS, the Technic Hovercraft set is brought to life.

The Design Phase:


Young-jun came up with the idea to create a MINDSTORMS food truck when he saw the two sets. He was inspired by the propellers and linear actuators in the Technic 42076 set. The propeller parts looked like the exhausts of a food truck to him. The linear actuators could be used to open and close a door on the side of the truck just like in a real food truck.

A food truck is a common sight in all major cities around the world. The side of the truck lifts up to reveal a vendor who prepares and serves the food from inside the truck itself. The elements in the Technic set gave Young-jun the inspiration to create a truck with a side that lifts up. He started with the following detailed sketch which included the two key LEGO elements and explained how the mechanization might work.


How it Works:

Young-jun's final model remains very close to his original sketch. The mechanism for this model is simple. The side door is activated using the touch sensor. The same sensor is used to both lift open and close the door.  In addition, the vendor inside the truck serves food when activated using the infrared sensor.  When you wave your hand in front of the infrared sensor, the vendor raises his arms and serves two options. When you pick one of the options, the vendor says, "Thank you!"

For additional playability, you can manipulate the wheels of the food truck and spin the large propeller blades by hand. You can watch the video below to see the model in action.

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...

ROBOTMAK3RS Review: LEGO River Steamboat

By Asha Seshan - ROBOTMAK3R
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...
