FLL Mission Overview Part 9 - Coal Mining


Objective: Get the Rail Car to roll down the track. Only when the car has touched the stoppers at the end, is the team allowed to retrive the cart by hand to Base.

Point Worth: 10 points

Mission Location: South (bottom) East (right) side of the mat.

Estimated Difficulty Level: 4/10

Time Length Rating: Medium

Unique Challenge Aspects: This mission in itself is not difficult. Bump the trigger, cause the car to roll down the tracks, and then pick it up. Then why the relatively high ratings for difficulty and time? The trigger is in the corner of the table. To achieve the presicion required to bump the trigger, the robot is going running a rather slow speed, so we have rated this mission a medium time length rating. Also, to get into the corner, bump the the trigger, and get out of there without getting tangled is why we have rated the difficulty 4 out of 10.

This mission is also rather unique, due to the unusual use of human hands. This was once done before, in Ocean Odyssey, when you were required to bump the pipeline. But in this case, the human hand cannot be shaky or hasty, or they may cause the car to spill all the coal! Which is a good question... "What happens to the coal that is spilled in the case the human hand splls it in an attempt to retrive the car?"

Finally, this mission is required in order to fully complete the Power Plant Supply. Another interesting aspect is in that somehow, either by human hand or by robot, the red coal must be sorted through the black coal, in which the black coal must be sent to the Power Plant Supply. When sorting, it has to be relatively quick in order to save time, not waste time sorting.

What appears to be a simple mission actually turns out quite complex...

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

MINDSTORMS Retires!

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
