Cardboard Robot is an active item in Revelations, a mod for The Binding of Isaac.

Turns Isaac into a robot for 17.5 seconds that can rapidly shoot a burst of short-ranged spectral lasers.

When the robot lands onto Isaac, it deals 75 damage to nearby enemies.

Lasers deal 1.6 + CurrentFloor × 0.2 damage, and can chain through multiple enemies.

While active, the duration (displayed as a timed recharge in the active item HUD) can be extended via normal recharge methods. Clearing a room will refill 30% of the charge.

Taking damage will waste 25% of the duration but won't actually hurt Isaac. This can also be used to play Blood Donation Machines without using health.

When the duration expires, the robot will jump off of Isaac and explode, dealing 100 damage to nearby enemies, but can also hurt Isaac for a full heart.

The effect can be ended prematurely by using the active item again. This will still waste the full charge.
