Real-World Robot Solution Contest Winners

Guest post from Dan below:

Thank you to everyone that has taken part in the recent contest to design and build a robot for an industrial application. The response to the contest exceeded my expectations, and for several weeks it was a challenge just to keep up with all the excellent questions from all the designers!

I met with several members of my company to review the design submissions, and I wish you could have seen the reactions of the group as they watched the videos, reviewed the CAD designs, NXT programs, pictures, and all the material that we received. Most of the review panel was made up of seasoned engineers and industry veterans, and they were all completely impressed with the level of professionalism and ‘out of the box’ thinking that was displayed. Our company is very supportive of creative ideas and collaborative thinking, and this project definitely extended our pool of creative thinkers!

We judged all the submissions on these criteria:

Robustness: Will the robot be able to withstand the rigors of a factory environment, and be able to run continuously? Was there a 24 hour test conducted and reported?

Presentation: Did the designer submit all the necessary items (Video of a working robot, CAD drawings, Build Instructions, NXT program)? Was there a WOW factor?

Repeatability: Does the robot deliver the required amount of pellets in the specified timeframe? How much variability was there?

Quick Change: Can the pellets be changed from one color to another easily, or is there some manipulation required?

No Spills or Contamination: Do the pellets get delivered without spilling? Is it an open or sealed container?

Simplicity: Is the design simple and clean looking, or complex?

Each criteria was rated on a scale of 1 to 5, then all the scores added together for a final score. I will contact each person directly to let them know what their actual score was, but here are the results:

Gold Prize: Jonathan, for Pellet Picker $125

Silver Prize: Dismay, for Pellet Mover $75

Bronze Prize: RoboLab 2.9 for The Pellet Machine $50

Lego Maniac for ColorScoop $50

MindStorms Kid for Wire-Me $50

Tnxt for PelletBot $50

Our next step (NXTStep!) is to purchase an NXT unit and to build Jonathan’s robot and do some extended tests to verify the robustness, accuracy, and repeatability. If we’re confident that it will stand up to our industrial environment, we will be using the robot in our process! We may also work with the team of designers above to collaborate on working through any issues that may come up during our extended trials.

Thank you again for taking part, it has been a great experience, and perhaps we’ll think up another contest in the future!


Congratulations to the winners from all of us here at The NXT Step blog. We'll be on the lookout for similar projects in the future. That said, if you work for (or own) a company that has an idea for possibly integrating the NXT robot kit into a work project, let us know and we might be able to help facilitate a future contest for you.

2023 is the 25th Anniversary of the MINDSTORMS brand. For 25 years, MINDSTORMS has educated and inspired a generation of robot builders, both children and adults. Unfortunately, the LEGO Group decided to end the line on December 2022. Many ROBOTMAK3RS have been passionately involved with the development of MINDSTORMS through the MUP and MCP programs. Even with the newest Robot Inventor line, several ROBOTMAK3RS were invited to submit additional bonus models that were included in the official app. Regardless of the retirement of a major LEGO robotics product line, ROBOTMAK3RS continue to MAKE-SHARE-INSPIRE using all LEGO robotics platforms available to us. Here is the official statement from LEGO. Since its launch in September 1998, LEGO MINDSTORMS has been one of the core ‘Build & Code’ experiences in the company’s portfolio, carrying with it significant brand equity and becoming a stand-out experience for the early days of consumer robotics and leading to current Build & Code

Celebrating MINDSTORMS with a Remix Part 1

In honor of the 25th Anniversary of MINDSTORMS, we asked ROBOTMAK3RS to combine a LEGO set of their choice with a MINDSTORMS set. Here is what these five ROBOTMAK3RS came up with.  MINDSTORMS Chess Assistant by Arvind Seshan Overview: When you are new to chess, it can be a challenge to remember which pieces go where. Now, you can use machine learning and LEGO MINDSTORMS Robot Inventor to build a tool to help you learn where all the chess pieces go on the chess board. Sets used: LEGO® Iconic Chess Set (40174) and MINDSTORMS Robot Inventor (51515) Review: I really like how the chess set base can store all the pieces underneath and that the board neatly splits in half for handy storage. The chess pieces themselves are very sturdy and well built. My only criticism is the building of the box itself. It was quite difficult to see what pieces to use and since the entire box is made mostly of thin plates, it took a lot of time and patience. I would have liked the storage area to be sliding dra

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
