Abstract: A self-configuring robotic system and method are disclosed. The system employs a computer having a central processing unit and an operating system containing at least a nucleus, a sequence reprogrammer and task support services. A robotic device and at least one defined task performing device, which may be another robotic device, are used in the system. Each device has a corresponding module that is electrically connected to the device and provides all of the intelligence for the particular device. Each module also provides a control block flag and a starting offset for the computer. The modules are electrically connected to the computer through a plurality of physically separable electrical connections so that all of the intelligence for the devices is on the device side of the associated physically separable electrical connections.

Abstract: An automatic liquid sample-injecting apparatus using a conduit such as a hypodermic needle or pipette to suck liquid from a sample source and transfer it to an injector valve apparatus. The apparatus utilizes the optimum embodiment of the apparatus being equipped with (a) novel seal means adapted to exert a radial thrust or wiping action on the conduit and (2) novel conduit working means featuring both a drip-proof means to supply a non-contaminating solvent for washing the exterior of the needle and means to remove such solvent, all without interfering with the use of the needle in a series of automatic injections.
