People are often surprised to learn that many of the most capable and high-tech robots are kept in cages away from humans.
This isn't because the machines are out to get us.
Many machines are dangerous because they simply lack self-awareness and the ability to understand their surroundings.
This is why, up until recently, robots haven't been able to work side-by-side with people in industrial settings.
Baxter by Rethink Robotics, however, is an example of a machine that can work with people.
The robot has eyes on a screen to show where the machine is "looking" to signal its next task.
