Building A 52 INCH Robot With Arm
How The Arm Works
This arm doesn't work like most robotic arms. It works more like a forklift. The hand will ride up and down on a wooden rail. This will allow the robot to lift an object 3' 4" off the floor using little torque.
For a normal robotic arm to lift an object 40" off the floor the arm would have to be 20" long. A 2 lb. object would take 640 oz. in. of torque to lift.
Using a 1" wheel to lift the 2 lb. object would only take 16 oz. in. of torque.
The math used to find the object in 3-D space is also easier.
