impressive given the quality load cell and vehicle multiple changes in project and scope LANDER initially chose
manufacturing from AXFAB. very cheap load cells since the test stand demonstration was
originally mean't to be a verification for much larger goals.
Acquiring usable data from the load cells ended up taking much
more time and resources than the team initially expected, but
thanks to proper risk mitigation the team was able to overcome
the challenge and find a real solution.
