The most compact scheme that allows you to lock your horizontal layers
with a vertical beam is the one shown in Figure 1.7: a beam and two plates, cor-
responding to five plates.Two holes per five plates is the only way you can con-
nect bracing beams at this distance.You can find it recurring in all TECHNIC
models designed by LEGO engineers, and we will use it extensively in the robots
in this book.
