Abstract
A load transducer for use in an automated control system such as those used in robotic assemblies, and other linkage systems separated by joints. The transducer is capable of measuring force and moments transmitted by the joint of the robotic assembly. This localized sensory data is utilized by a microprocessor to control the motion of the linkages of the system. In addition to being very accurate and reliable, the load transducer has a low profile and small size. This invention is easily manufactured using strain gage technology.
Claims20
A load transducer comprising, in combination:
- a frame having a base with an upper surface and a plurality of beams extending from the base, each of the plurality of beams including a lower surface that is spaced apart from, and faces in an opposing relationship, the upper surface of the base, each of the plurality of beams further including at least one cantilevered end;
- and
- at least three load cells, each of the at least three load cells being located near a respective one of the cantilevered ends of the beams, the at least three load cells configured to measure a force and its position.
A load transducer comprising, in combination:
- a frame having a base with an upper surface and a pair of double-cantilevered beams disposed at lateral sides of the base, each of the double-cantilevered beams including a first beam section extending in a first direction and a second beam section extending in a second direction that is opposite to the first direction, the first beam section and the second beam section each including a lower surface that is spaced apart from, and faces in an opposing relationship, the upper surface of the base, each of the double-cantilevered beams further including two oppositely disposed free ends;
- and
- a plurality of load cells, each of the plurality of load cells being located near a respective one of the free ends of the double-cantilevered beams, the plurality of load cells configured to measure a force and its position.
