Question 1: Spot The Difference

For the first robotics question, we were asked to find a difference between different lego pegs.

The difference I found was in the levels of friction provided when different pegs were used to attach beams. While the grey and beige pegs allowed the pegs to spin and move freely, the black and blue pegs required a slight amount of assistance in spinning and moving the pegs. So although the blue and beige pegs are alike in length, they are different in friction levels. In the same way that although the black and grey pegs are the same length, they also provide different levels of friction.

The red peg is similar to the blue and black pegs, in that it requires assistance in moving the beams attached to it
