How to Build and Program The Snatcher: A Robotic Arm with LEGO MINDSTORMS NXT 2.0
If you are looking for a fun and challenging project with your LEGO MINDSTORMS NXT 2.0 kit, you might want to try building and programming The Snatcher, an autonomous robotic arm that can find and pick up objects. The Snatcher is one of the robots featured in The LEGO MINDSTORMS NXT 2.0 Discovery Book by Laurens Valk, a comprehensive guide to building and programming NXT robots.
The Snatcher uses two NXT motors to control a set of treads, allowing it to move in any direction. It also has a third motor that operates a grabber mechanism, which can open and close to grasp objects. The robot uses an ultrasonic sensor on port 4 to detect objects in front of it, and a touch sensor on port 1 to sense when the grabber is closed.
