Ultra-light and ultra-accurate portable coordinate measurement machine
First Claim
1. A portable coordinate measurement machine (CMM) comprising:
- a manually-positionable articulated arm having first and second ends, the articulated arm including a plurality of arm segments and a plurality of rotary joints, the first end including a measurement probe and the second end including a base;
wherein at least one of the rotary joints includes;
first and second bearings;
a shaft that engages an inner diameter of the first bearing and an inner diameter of the second bearing, the shaft configured to rotate about an axis of rotation of the first bearing and the second bearing;
a housing having at least one port that engages at least one of an outer diameter of the first bearing and an outer diameter of the second bearing; and
at least one transducer configured to output an angle signal corresponding to an angle of rotation of the shaft relative to the housing about the axis of rotation, whereinthe measurement probe includes a handle mechanically but not electrically operably coupled to the first end, the handle rotatably coupled to the first end to rotate about a central axis of the measurement probe, the handle including;
a wireless transmitter; and
at least one switch operably connected to the wireless transmitter and configured to, when pressed, cause the wireless transmitter to transmit a wireless signal that corresponds to the CMM taking a measurement.

Abstract
A portable coordinate measurement machine includes a manually-positionable articulated arm having first and second ends. The articulated arm includes a plurality of arm segments and a plurality of rotary joints, the first end including a handle mechanically but not electrically operably coupled to the first end, the handle rotatably coupled to the first end to rotate about an axis, the handle including a wireless transmitter and at least one switch operably connected to the wireless transmitter and configured to, when pressed, cause the wireless transmitter to transmit a wireless signal that triggers capture of an angle signal corresponding to an angle of rotation about the axis.
