Dynamo
From Ratchet & Clank wiki
Megacorp's Dynamo was designed to temporarily activate certain pieces of machinery, namely holographic platforms for hard-to-reach places. In Up Your Arsenal, the Dynamo and Swingshot were combined into one gadget, the Hypershot.
[edit] Trivia
On planet Endako if you use the Dynamo on the pyramid in Clank's Apartment you can play a minigame.
