  WEAVE is a 1000-fiber multi-object spectroscopic facility for the 4.2~m
William Herschel Telescope. It will feature a double-headed pick-and-place
fiber positioning robot comprising commercially available robotic axes. This
paper presents results on the performance of these axes, obtained by testing a
prototype system in the laboratory. Positioning accuracy is found to be better
than the manufacturer's published values for the tested cases, indicating that
the requirement for a maximum positioning error of 8.0~microns is achievable.
Field reconfiguration times well within the planned 60 minute observation
window are shown to be likely when individual axis movements are combined in an
efficient way.
