Futek miniature load cells enabling robotic tactile sensing

Tactile sensing in robots comes from external sensors, which help them
determine the force being applied to objects. Miniature load cells are placed
in the robot’s grip points to provide the necessary force feedback to safely
grip objects.

The conceptual diagram displayed above shows how multiple load cells are
being utilised to measure the tactile force produced by an industrial robot.

In this application, a miniature load button is mounted to the tip of
each robotic finger. As the robotic hand manipulates different objects, the
force required to handle those particular objects is collected and streamed by
research engineers directly onto a PC using FUTEK’s USB solution with the LLB miniature
load buttons. Utilising FUTEK’s SENSIT Test & Measurement Software, the engineers
will be able to live graph and log all the data.

With continuing research and development into robotics, there is a
greater need for high precision test and measurement products in the industrial,
medical and manufacturing sectors. FUTEK load cells and instrumentation will
provide the accuracy and certainty required for this precision testing.

FUTEK products used in this application include LLB Series miniature
load buttons, a high resolution USB output module, and the SENSIT Test &
Measurement Software.
