Track Star

Students at Cornell College made a robot that can walk for 11 hours straight before having to be charged up again. Ranger, the robot, made about 108.5 laps around a 212 meter track field, which is about 70,00 steps for it. That is 14.3 miles! The goal of this project led by Andy Ruina was to show off the way that the robot uses its energy and how fluently it can walk. This robot is able to walk like a human and it uses gravity to help it walk.

This article is related to science because if this robot is able to store enough energy to walk 14.3 miles. This is new technology that might be able to help us by making our cell phone battery last longer instead of dying in a day. It is also related to science because it might be able to help us build a better machine for people who cannot walk.

This is important because it can help us improve on the things we have now such as cell phones and things that require electricity. This can also help people who cannot walk. This is also important because it might also give scientists ideas of how to improve athletic performances. They can do this by observing the way the robot walks and how its able to walk 14.5 miles.
