From Angles to Action: Defining the Robotic Arm Challenge
How can we use angles and motion math to design a robotic arm that helps a real person with their task?
Learning Intentions:
Use angles, radians, and arc length to describe and quantify repetitive motions to solve real-world problems with robotic arms.
Today's Concept:
On your Spec Sheet yesterday, you estimated that your user needs a robot to sweep 'about 90 degrees.' That's a good start. But if you tell a robot motor to move '90,' it might not know what you mean.
Does '90' mean 90 degrees? Or does it mean 90 radians? The difference is huge. 90 degrees is a quarter turn. 90 radians is more than 14 full spins! To build a safe robot, we have to speak its language precisely. Today, we learn the two dialects of rotation—degrees and radians—and how to use them to calculate exactly how far the robot's hand will travel through the air.
