Robot end effector for dispensing an extrudable substance

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;
• a plunger assembly, comprising pairs of plungers and arranged to concurrently extrude contents of the two-part cartridges through the cartridge outlets, when the two-part cartridges are received by the cartridge bays;
• and
• an electric motor, attached to the chassis and configured to selectively move the plunger assembly relative to the chassis.
