Calibration of an industrial robot using a cable robot and a laser tracker

This is the first video presenting CabOLS, our Cable-actuated Omnidirectional Load Simulator, which is essentially a cable robot. CabOLS is used to apply various loads to the end-effector of an industrial robot. The exact load applied is measured using a force/torque sensor attached to the end-effector of the industrial robot. A laser tracker is used to measure the deflection of a point on the end-effector after the load has been applied. The whole procedure is fully automated.
In this particular video, we use the position and wrench measurements to calibrate the industrial robot and then validate its position accuracy.

Absolutely amazing method, well done!

What a robot fight!

[@brijubatt]

well done, it is possible to do an experimental stiffness map of any robot inside its workspace

[@CoRoETS]

Thanks. Yes, exactly.

[@midoahmed612]

sound track name ?

[@agustinauta]

less cost than a manual calibration with only manual laser tracking 👍

[@aliozturk57]

Do you have any technical paper regarding to this work?

[@Octavarium666xyz]

etsmtl.ca/Professeurs/ibonev/documents/pdf/ICRA16_0179.pdf it's most likely this paper

[@user-jk6pw8fl1y]

Why you add spring to cables?

[@ashfordnichols3622]

Tensioning most likely

[@WesleyLeeYang]

That is how the external load is added. The more you pull the spring, higher the force. (Probably the easiest method of adding variable loads using servos/steppers).

too slow... chinA AND JAPAN CAN DO 10X FASTER WITHOUT SPEED UP THE VIDEO HAHAHHAA NO DOUBT GERMAN STILL TOP IN ROBOTIC BUT NOWADAYS JAPAN, CHINA, ASIAN TIGERS START TO CHALLENGE THE STATUS QUO
