NXT 2.0 Dial Remote Control

I have posted an NXT 2.0 Dial Remote Control project, which is an updated version of the NXT 1.0 version posted last year. This is a simple-to-build and sturdy remote control designed for NXT-to-NXT Bluetooth control, which has a somewhat unique feature in that you can get very smooth and progressive movements based on the way that the dial control works (the speed of the dial rotation maps to the robot motor speed instead of the usual dial/lever position technique). This control works particularly well to control the Forklift project.

In addition to the Bluetooth programs (one for the remote and one for the controlled bot), the project includes a program that shows how you can use the Dial Remote Control to control two motors via wires, with only a single NXT kit. Along these lines (wired remote control), I also posted a separate Mini Rover with 3-Button Remote project that shows a much simpler wired remote program using only the 3 buttons on the NXT.

To throw in something new for the Dial Remote Control over the 1.0 version, I added a touch sensor to give you five total actions to choose from, and also a bar to prevent you from accidentally pressing the dark gray program abort button by mistake when using the remote.

The NXT 2.0 Dial Remote Control is similar enough to the 1.0 version that I didn't make a new video, but here is a video of the 1.0 version controlling the 1.0 Forklift project.

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
