EOD Bomb Explosive Ordnance Disposal Robot

Projected water disruptors use a water projectile shaped charge to destroy bombs, severing any detonating cord. One example is the BootBanger, deployed under the rear compartment of cars suspected to be carrying bombs. Projected water distruptors can be directional, such as the BootBanger; or omni-directional, an example being the Bottler.
- Pigstick
"Pigstick" is a British Army term for the waterjet disrupter commonly deployed on the Wheelbarrow remotely operated vehicle against IRA bombs in the 1970s. It fires an explosively-propelled jet of water to disrupt the circuitry of a bomb and thereby disable it with a low risk of detonation. The modern pigstick is a very reliable device and fires many times with minimal maintenance. It is now used worldwide. It is about 485 mm long and weighs 3 kg. It is made of metal, and can be mounted on a remotely operated vehicle (ROV). These factors make it a very effective, safe way to disarm bombs. The "Pigstick" is also known as the PAN (Percussion Actuated Neutralizer), or just water cannon.
The name pigstick is an odd analogy coming from the verb meaning “to hunt the wild boar on horseback with a spear.”
