Robotics Monday: NXT-based robotic arm

Name of Model: The Better Arm
Created by: Patrick Miles
Found at: and
Here's a nifty LEGO MINDSTORMS NXT-based robotic arm. It uses a slider mechanism to keep its hand at the same angle at all times (which makes it easier programming-wise to determine the hand's locations). I'm surprised by the way that the center-of-gravity is kept in place by a wheel-based counterweight instead of with an actual LEGO® counterweight brick.
This is Monday's model of the day.
