This project is based on my universal balancing robot code. These small balancing robots are fun, but I wanted to make something that more closely resembles a real Segway.

Everyday activities exercises

The Segway program turns these signals into movement. In the video, Unicycle NXT. Then I thought that one wheel might be enough to stay up right, and it was.

I know this is not a true unicycle, Printer NXT. This machine plots drawings on standard A4 or US letter paper. The robot is featured in the NXT 2. It can be built with Lizard NXT.

This 4 legged lizard walks around and shows different behavior, depending on sensor readings. It is featured in the NXT 2. It can be Jeep NXT. This Jeep style vehicle has front wheel drive and front wheel steering, and it is featured in the NXT 2. It can be built InventorBot NXT. Throughout the book, the basic robot is expanded to SentryBot and Table-Bot shown above.

Most NXT contraptions that move with wheels go forwards, backwards, left, or right. This robot can do none of this, but instead it can go up and down. This robot is featured in Chapter 15 of the Discovery Book. Other chimney climbers in this series: Every time I created a new climber, I tried to This robot is featured in Chapter 14 of the Discovery Book.

Other brick sorters in this series: Every time I created a new brick sorter, I tried to tackle a new design challenge. This improvement would make The Snatcher NXT.

Make the robot go back and forth when the Touch Sensor is pressed. Now select Loop [Loop] to make the Now you can run the program.Lego Mindstorms is a hardware and software structure which is produced by Lego for the development of programmable robots based on Lego building blocks.

Each version of the system includes an intelligent brick computer that controls the system, a set of modular sensors and motors, and Lego parts from the Technic line to create the mechanical systems. With each platform release, the motor and sensor capabilities expanded. The Lego Group began a partnership with Papert's Media Lab, funding their research and sharing ideas. The Liquid Crystal Diode LCD display that the two bricks share was specifically requested by teachers interviewed by the Epistemology and Research group, in order to give readouts of the status of the motors or sensors in real time.

Before Mindstorms, Lego had previously done some experimentation with robotic sets. One of the main foundations of these sets was the Lego Technic system and its 4. These sets from the mid-late s provided a dedicated hardware interface to control the Lego Technic 4. This interface was controlled from an IBM-PC or Apple-IIe by the use of a special version of Logoa simple programming language designed for use in children's education.

Organ stop combinations

It is worth noting that the Control Lab had dedicated ports for active and passive sensors, while later products like first generation Mindstorms provided support for both kinds on the same ports. The control center was the first programmable standalone Lego product, in the sense of being able to store sequence-based programs and run them. It featured three output ports and manual control, and it was only capable of storing linear sequences of manual input plus timing information.

It could store up to two programs at once. The manual controls could be used to independently control the three motors. To record a program; the controller had to be put in programming mode, and then any manual control would be recorded to the program. Pauses could also be included in a program. When the recording was done, the controller could successfully recall and execute any manual action done during the recording. The executing program could be set to loop infinitely. It was aimed at an older audience as an early attempt of merging with robotics and Lego.

The brick shares many, especially software, features with the RCX but differs in appearance and technical specifications: one output plus two built-in and four sensors. It talks the same protocol as the RCX but cannot communicate directly to it due to IR vs RF but with a repeater a computer with 2 serial ports and a simple program they can communicate indirectly.

Sold as part of the Barcode Truck kit. This unit was the first programmable brick or Pbrick. It features a single motor, a single touch sensor and a light sensor.

It is programmed by setting it to 'learn' and using the light sensor to feed barcoded commands. The command set is very limited. Since barcode is just a series of variances in light, this form of command entry was dubbed VLL Visual Light Link and has been used in several later Lego models. Instead of being based on the RCX, it had its own programmable brick called the Scout.

An even simpler version of the Scout would be featured in two Star-Wars themed Mindstorms sets as well. Lego also released a blue computer called the Scoutwhich has 2 sensor ports, 2 motor ports plus one extra if linked with a Micro Scout using a fiber optic cableand a built in light sensor, but no PC interface.Program Downloads There are two kinds of program download links you will find on this site.

If the program download looks like the following:. Your computer must be able to read zip files to read these. Most newer computers can read and open zip files directly, and you will be able to see the files inside after downloading it and selecting "Open" when prompted for what to do with the file. On some computers, you may need to download and install an "unzip" utility many are available for free. On some systems, you may need to save the. Once you reach an NXT program file.

Required Software The downloadable programs for the projects. If you are getting " Error " or " The program is broken. It may be missing required files ", you are most likely trying to load an NXT 2.

X or other older version of the software. If you have the correct NXT software installed but you still get an error trying to load or compile a downloaded program such as "Invalid program file", or "Internal Compiler Error", it is possible that the file was not downloaded completely by your browser or was corrupted.

If this happens, try downloading the program again. If you want to save the program to the default location for NXT program files, this location will be something like the following:. The NXT 2.

Attach one motor to Port A and the other motor to Port C. You will need an NXT car with two motors and a touch sensor. Attach the touch sensor to Port 1. Add a second Wait block just after the first Wait block and before the Move block. Set one Wait block to wait until the touch sensor is pressed, and set the second Wait block to wait until the touch sensor is released. Compare the efficiency of the code — which do you find easier to make in NXT-G?

Make the car continue to drive forward each time the touch sensor is pressed until the touch sensor has been pressed four times in total. Hint: Change the settings of the Loop block.

Set the Control to Count, and change the count number. Change the direction of each Move block so that at least one Move block causes the car to turn. Now you can control which way the motors turn by pressing a single touch sensor! What are the limitations of this program?

What would you like to change about the program? You will need an NXT car with two motors, a light sensor, and black electrical tape. Attach the light sensor to Port 3. Pretend your motor is a generator. Program the generator to turn on when the lights in the room go off, and to turn off when the lighs in the room come back on. The program should be able to perform these tasks repeatedly. Hint: Use one or more loops!

Think about building something other than a car that could do two things at the same time and would need a split task. What would you build and what would it do? You must be logged in to post a comment. Write a program exactly like the one above. Make sure to change both Move blocks to Ports A and C. Set the Duration of each Move block to 2 seconds. The second Move block should have the Direction set to Reverse. Run the program, and observe the behavior of the NXT car.

Change the amount of time that your car moves forward and backward. Run the changed program and again, note the behavior of the NXT car. Make sure to change the Move block to Ports A and C. Set the Duration of the Move block to 2 seconds. The Wait block should be set to wait for the touch sensor to be pressed. Run the program, and observe the behavior of the NXT car when you press the touch sensor. Change the Wait block to wait for the touch sensor to be bumped pressed and released once.

Extra challenge Add a second Wait block just after the first Wait block and before the Move block. Loop You will need an NXT car with two motors and a touch sensor.

The loop should continue forever.The main difference between the NXT system the Programmable brick, motors and sensors and the EV3 system is the brick itself. In addition, it has a slightly larger screen, more buttons, and it is possible to control the EV3 brick using both iOS and Android devices, as opposed to Android only for the NXT. See this article for a list of technical specifications of both bricks.

On first thought, you may wonder why you would need these features. First, the micro SD card slot can be used to add extra storage to the brick by means of a micro SD card.

NXT-G: the development environment supplied with Lego Mindstorms, NXT-G

Additionally, the USB port can be used to link up to four EV3 bricks so that you can control up to 16 motors and 16 sensors on one robot. Although the general user will not notice on the outside, the brick runs a Linux based operating system.

Basically, this means that your robot almost resembles a full computer, a bit like the Raspberry Pi! Both versions of the EV3 set come with a variety of sensors see details; coming soon. Figure 3 shows the complete family of EV3 electronic components.

Both versions of the EV3 set contain two Large motors. They are comparable to NXT motors in terms of speed and torque, although their shape is slightly different to make building easier.

In addition, both sets have one Medium motor, comparable to the Power Functions Medium motor. As is the case for NXT, all three motors have rotation sensors for position and speed control. Some combinations are compatible, others are not, as discussed in the next.

You can see a demonstration of two possible configurations in the following video. If in doubt, contact the manufacturer of the sensor. If you have a very old version of the NXT Touch sensor, it may not be compatible with the EV3 without some modifications see the comments by Philo below. Figure 5 illustrates this see video above for a sample program. Alternatively, they can be powered with a LEGO rechargeable battery.

The EV3 brick is programmed with new programming software. Note that this does not give your NXT brick additional features.

It just helps keeping all your programs in one place. Feel free to post questions in the comments below.

If you find any errors, please let me know. And can you connect a Nxt and an ev3 together??? We currently have lego mindstorms nxt from 8 yrs ago and missing some pieces.Play around with Lego Mindstorms NXT enough and at some point you'll inevitably get frustrated with NXT-G, its graphical programming language of "blocks" that you drag around and connect with "wires". It's great for teaching kids the basics, but once they embark on anything remotely ambitious they're bound to run into trouble.

Whether it's the crazy sprawl of blocks over the work area even a simple loop can require screens of slow horizontal scrollingthe lack of floating point math or, perhaps worst of all, the total absence of debugging tools, sooner or later you're going to start longing for a proper programming language that uses, you know, text and stuff.

For anyone who's ever programmed, there's nothing better for understanding programming logic than properly tabbed and commented code, all in a column of text as God intended. And for your kids, there's no time like the present to introduce real programming, using coding conventions that will be as relevant in the decades to come as they were in decades past.

The good news is that there are lots of replacement text-based languages for Mindstorms NXT, from Java to Lua or, if you want to stick with visual programming, you can also use LabViewthe professional-grade language that NXT-G is based on. Even better news: I'm here to tell you that one stands out from all the rest. It's RobotC and it's simply fantastic.

But where it really stands out is in the programming environment. RobotC's integrated development environment IDE includes real-time syntax checking, compiling and contextual help and auto-complete of functions and variables. It has an awesome debugger, allowing you to step through your program, set break points and watch variables, or just watch the code executing on the NXT brick.

And its collection of instructional and sample programs is unmatched in the Mindstorms world. RobotC got its start at Carnegie-Mellon, the nation's top robotics school, and the pedigree shows.

But special credit should go to Dick Swan, who authored much of the current program. Dick, get a home page so I can link to you! Plus if you want to teach your kids real programming, why not introduce them to a real programming language? Aside: as I was re-teaching myself how to program in C, I was reminded about the funny logic of computers.
