Title: Robotically manipulable sample handling tool

Abstract: A robotically manipulable sample handling tool, such as a colony picking head or robotic pipetting tool, includes needles arranged on the tool. Actuators may be associated with each needle to control flow for the needle, e.g., to move the needle and/or draw fluid into/expel fluid from the needle. The actuators may be arranged so that needles are individually controlled by a controller that outputs a number of control signals that is less than the total number of needles. The actuators may be membrane valves that receive two signals from a controller; a first signal that opens or closes the valve, and a second signal that causes fluid flow through the valve to actuate a needle.
