1. A robot end effector for dispensing an extrudable substance, the robot end effector comprising:
a chassis;
cartridge bays, attached to the chassis and each shaped to receive a corresponding one of two-part cartridges;
a dispensing valve, attached to the chassis and comprising a valve inlet and a valve outlet, wherein the valve outlet is in selective fluidic communication with the valve inlet;
a manifold, comprising a manifold outlet and manifold inlets, which are in fluidic communication with the manifold outlet, wherein:
the manifold outlet is in fluidic communication with the valve inlet, and
when the two-part cartridges are received by the cartridge bays, the manifold inlets are in fluidic communication with corresponding ones of the two-part cartridges via static mixers, attached to cartridge outlets of the two-part cartridges; and
a head assembly, comprising pairs of fittings, configured to selectively supply compressed air from a pressure source to the two-part cartridges when the two-part cartridges are received by the cartridge bays, so that contents of the two-part cartridges are concurrently extruded through the cartridge outlets.
