Using LEGO Biters to Remove "Dynamite" (sections of swimming noodles Velcroed to a string)
Biters are another fun, linkage warm-up project. They use a scissor linkage for an extendable neck, and, unlike "grabbers", as the neck extends the jaws get wider, until a trigger mechanism snaps them shut at full extension.
Biter battles are fun, and guarantee that students will innovate to win - but NEVER aim a bite at someone's face!
