One of the most impressive and popular robots that you can build with LEGO MINDSTORMS NXT 2.0 is The Snatcher, an autonomous robotic arm that can find, grab, and lift objects. The Snatcher is featured in Chapter 13 of The LEGO MINDSTORMS NXT 2.0 Discovery Book, a book that teaches you how to build and program NXT robots.
In this article, we will review The Snatcher and see what makes it stand out among other NXT robots.
What is The Snatcher?
The Snatcher is a robot that can move around on treads and use a grabber to pick up objects. It uses two NXT motors to control its movement and one NXT motor to control its grabber. It also uses an ultrasonic sensor to detect objects and measure their distance.
The Snatcher can operate in two modes: manual and autonomous. In manual mode, you can use the NXT buttons or a remote control to drive the robot and operate the grabber. In autonomous mode, the robot will scan its surroundings and try to find and grab objects on its own.
The Snatcher is a complex and challenging robot that requires advanced programming skills. You will learn how to use variables, loops, switches, logic blocks, math blocks, and data wires to create a program that controls the robot's behavior.
What makes The Snatcher stand out?
The Snatcher is not just a simple NXT robot. It has many features that make it unique and innovative, such as:
Partial free roam: The robot can move in any direction by adjusting the power and direction of the driving motors. You can also control its speed by using a variable.
Mechanics never seen before in an NXT robot: The robot uses a clever mechanism to open and close its grabber with just one motor. The grabber can also rotate up and down to adjust its angle.
Interactive cinematic cutscenes: The robot has several cutscenes that show its personality and emotions. You can also influence some of these cutscenes by making choices that affect the outcome.
Multiple endings: Depending on your actions and choices throughout the program, you can get different endings that reveal different aspects of the robot's story.
Graphics powered by NXT-G: The robot uses custom graphics made with NXT-G blocks to display images and animations on the NXT screen.
Unique Soundtrack: The robot has an original soundtrack composed by Laurens Valk that fits perfectly with the mood and theme of the program.
Fully voice acted: The robot has professional voice acting by Jessa Quinn that brings life to the dialogue and cutscenes.
How to build and program The Snatcher?
If you want to build and program The Snatcher, you will need a LEGO MINDSTORMS NXT 2.0 kit and The LEGO MINDSTORMS NXT 2.0 Discovery Book. You can find the book on Amazon or other online retailers.
The book will guide you step by step through the building and programming process of The Snatcher. It will also teach you many concepts and techniques that you can use for your own NXT projects.
You can also download the programs for The Snatcher from Robotsquare.com or from Laurens Valk's website.
Conclusion
The Snatcher is a LEGO MINDSTORMS NXT 2.0 robot that will impress you with its quality and creativity. It is a robot that will challenge you, entertain you, and make you think. It is a robot that will make you appreciate the possibilities of LEGO MINDSTORMS NXT 2.0.

What are some tips and tricks for The Snatcher?
If you have built and programmed The Snatcher, you might be wondering how to improve your robot and make it more fun and efficient. Here are some tips and tricks that you can try:
Experiment with different objects: The Snatcher can grab and lift objects that are within its reach and that fit in its grabber. You can try different objects of different shapes, sizes, weights, and materials to see how the robot reacts. You can also try to stack objects or place them in different locations.
Adjust the parameters: The Snatcher has several parameters that you can change to modify its behavior. For example, you can change the speed of the driving motors, the angle of the grabber, the distance threshold of the ultrasonic sensor, and the duration of the cutscenes. You can also add or remove sound effects and graphics.
Modify the structure: The Snatcher has a sturdy and stable structure that allows it to move and grab objects. However, you can also modify the structure to make it more compact, agile, or powerful. For example, you can change the length of the treads, the position of the ultrasonic sensor, or the design of the grabber.
Add more sensors: The Snatcher uses only one sensor, the ultrasonic sensor, to detect objects. You can add more sensors to make it more aware of its environment and more responsive to your commands. For example, you can add a touch sensor to make it stop when it bumps into something, a light sensor to make it follow a line or avoid dark areas, or a sound sensor to make it react to your voice or clap.
Create your own scenarios: The Snatcher has a story that involves finding and grabbing objects in a hospital ward. You can create your own scenarios by changing the setting, the objects, and the objectives. For example, you can make it a rescue robot that has to find and save people in a disaster area, a spy robot that has to infiltrate and steal information from an enemy base, or a treasure hunter robot that has to explore and collect valuable items from an ancient temple.
