The importance and efficient usage of various pegs
To build your robot, you will have to connect different pieces to each other. As we use nuts and bolts in real life to connect two things, we will be using pegs in the BOOST kit for connections.
Tip
Always use at least two pegs to make any connection sturdy! Do you know that the two module pegs are of two different types? The one in black is a friction peg and the one in gray is a frictionless peg.
As you can see in the following photo, both the LEGO pieces connected with a single peg are not sturdy. They can move easily. This is not the kind of connection we would like to have in our robot, right?
In the following photo, we can see that both the LEGO pieces are now connected with two pegs! The structure is sturdy – the kind of connection that we shall need in our robot:
