NASA sends 3.5 tons of cargo to the ISS every 60-90 days. So highly trained scientist/astronauts spend 14 out of every 16 duty-cycle days moving things around. Ethan Barajas of Icarus Robotics says "it's kind of ridiculous that they do this," so his company built a robot to fix it. cc: @ethanbarajas11, @Icarus_Robotics, @alex, @Jason
