Short fibre characterization and manipulation platform

Custom design and build platforms for manipulation and handling small object (<2 mm in length)

Platforms consist of manipulators, sensors, optics to characterize samples.

Platform is designed for mechanical short fibre testing. This unique system can perform optical tomography (OPT), characterization of micro fibril-angle, 3-point bending and tensile/compression testing in a controlled environment.

System is especially designed for pulp fibres, but it works reliably with other materials also.

Features:
DOF manipulators, tensile, bending, buckling testing ,MFA measurement, OPT, humidity and temperature control.

Operations:
System is tele-operated via gamepad or spacemouse. The software runs in ROS (robot operating system).

Manipulators:
Manipulator with upto 6-DOF (XYZ, pitch, rotation, grasping). One of the manipulators is installed with force cell. Other is active with tensile causing actuator.

Platform with two 6DOF manipulators.
