摘要： The position of a working point relative to a working space, such as a working point of a carriage on a gantry beam of an XY positioning table, is determined by measuring at least two sets of displacements. A first set of displacements, of the working point relative to an intermediate component, such as the gantry beam, includes a relatively large displacement (X) in a first linear degree of freedom and relatively small displacements (Y1′, Y2′), in at least two of the five degrees of freedom other than the first. The second set of displacements, of the intermediate component relative to the working space, includes a relatively large displacement (Y1, Y2), in a second linear degree of freedom, and relatively small displacements (X1′, X2′), in at least two of the five degrees of freedom other than the second.

摘要： A robotic arm assembly is provided comprising a driving mechanism including a rotor which is rotatable relative to a stator. The rotor is coaxially rotatable about a columnar shaft having a substantially hollow central longitudinal axis. A first arm having proximal and distal pivotal ends is rigidly mounted on the rotor such that the first arm is drivable to rotate by the driving mechanism. A proximal pivotal end of a second arm having proximal and distal pivotal ends is pivotally connected to the proximal pivotal end of the first arm. A first timing pulley is mounted coaxially onto the columnar shaft, and a second timing pulley which is spaced from the first pulley is drivable to rotate together with rotation of the first arm. A timing belt connects the first and second timing pulleys and is operative to rotate the second arm relative to the first arm as the first arm is driven to rotate by the driving mechanism, such that the distal pivotal ends of the first and second arms are configured to always lie along a substantially straight line.
