ROBOTMAK3RS Animal Contest Winner: Menno Gorter

Every quarter, the ROBOTMAK3RS RLOC sponsors a community contest. Last quarter, builders were challenged with the task of creating a pet, a wild animal, or an assistant for the animal.

There were many creative entires including a dog, a snake, an ox and even a reindeer. The winning entry was an Omnispider by Menno Gorter from the Netherlands.

Menno has a long history building with LEGO robotics systems. He is most intrigued by creating movement without wheels. Hence, a large fraction of his work involves clever robots without wheels. The result is a vast collection of insects and various walkers with Menno's unique signature style to them. His work has been featured at various events including LEGO World in the Netherlands and Denmark.

ROBOTMAK3RS RLOC interviewed Menno to learn more about his creative process and learn about how the Omnispider works.

Why did you decide to build this particular model?

It began when the ROBOTMAK3RS challenged the community to make an animal-like robot. Given my history making spiders, I took this opportunity to create a SPIKE Prime spider. The new SPIKE Prime Hub is so much lighter than previous hubs that I thought this was a good opportunity to create a new version of the Omnispider. I have built Omnispiders before.

What was your process for creating this model?

I started by experimenting what the best setup would be for a sturdy way to attach the four motors to the hub. Because these were also the strongest and sturdiest parts of the design, everything else is mounted to these five parts. The first prototype took two days to get up and running. Then it took another two days to learn from it and tweak it to create the second prototype. It took another week to fine tune the programming, especially to get the movements of the legs correct.

Besides strengthening the legs to withstand the movement of the spider, the most challenging aspect of the project was giving the Omnispider character. The goal was to give the impression that it is exploring its environment tirelessly.

How does your model work?

The Omnispider uses four PowerdUp Large Motors. Each motor drives a pair of legs in a 90-degree angle which allows the robot to move in any desired direction. On top of this, the setup makes an octagonal orientation of the legs possible, which makes the movement much more spider-like. I have also used two Ultrasonic sensors and managed to use one of the Hub buttons as a touch sensor. The sensors are used by the Omnispider to detect obstacles in its path.

To see the spider in action, see the video on Facebook.

What advice do you have for a young person who wants to build with LEGO robots?

It may sound very simple, but, "never give up"!

Celebrating MINDSTORMS with a Remix - Part 3

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...

Celebrating MINDSTORMS with a Remix - Part 2

The ROBOTMAK3RS continued their celebration of the 25th Anniversary of MINDSTORMS through these summer and fall 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. Remote controlled material handle r by Jozua van Ravenhorst (aka Mr Jo) This remix combines the LEGO Technic Material Handler (42144) with MINDSTORMS EV3 (31313) It uses the power of pneumatic cylinders to move objects around. By using a bluetooth remote control, very precise movements can be made with this model. Touch sensors in the base chassis prevent the turret twisting the cables that go through the turntable to much. The program has several protections to prevent over pressurizing the system for each of the 3 individual pumps and valves that control the 2 booms and claws. The real version of this machine is mostly used in waste material sites to bring the material to machines that sort and...

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...
