HAL3000 & AS20
The HAL3000 plaster saw utilises an oscillating movement for cutting. The amplitude of the oscillation is such that the blade is able to cut the stiff material but not the soft material that adapts to or follows the movement. This allows the layer of plaster to be easily cut while leaving the skin underneath unharmed.
The AS20 vacuum cleaner works in combination with the HAL3000 plaster saw. It is lodged inside a trolley that makes the entire system easy to transport and housing the saw and accessories used. AS20 automatically turns on when HAL3000 is turned on, and it automatically turns off a few seconds after the saw is turned off.
