Effort measurement on an exoskeleton

Mesure d'effort sur un exosquelette

Customer

A manufacturer of autonomous exoskeleton that rely on robotic and artificial intelligence technologies to simulate human walking.

Problem

The manufacturer is in the prototyping phase and wants to know the different efforts applied to the ankle on a humanoid exoskeleton prototype, to qualify the balance, the behavior and the weight of the lower part of the exoskeleton.

Its major issues are mainly related to a reduced size 25x25mm, the possibility to measure very large efforts in the three directions and a great durability.

Solution

PM Instrumentation proposes to this customer the miniature triaxial force sensor, TR3D-B-1K. This miniature triaxial force transducer with a high capacity Fx=Fy=Fz= 4 KN and ultra-miniature dimensions: 25.3 x 25.3 mm can withstand high moments up to 65 Nm and long operating cycles, it perfectly meets the customer's requirements.

Results

The customer has an easily integrated solution that can withstand millions of cycles of use, with excellent measurement repeatability and high accuracy.
