Lesson 2
What is Object Manipulation?
Let's explore all the ways that robots can interact with different objects!
Step 1: Let's talk about Object Manipulators!
Plows apply force to one side of an object, pushing it out of the way rather than lifting it

Scoops apply force underneath an object to lift and carry it using gravity to keep the object in the basket
Friction Grabbers apply force in at least two locations on an object to pinch and carry it

Step 2: Exploring Lifting Mechanisms
A lifting mechanism is a system designed to complete assignments to lift items
There are 3 main types of Lifting Mechanisms:
1. Rotating Joints
2. Linkages
3. Elevators
Rotating Joints
Most commonly portrayed as an arm appendage that rotates around a central point to lift an object
Linkages
Linkages are made up of smaller components called links with freely moving joints, when the links move in tandem the output motion allows for an object to be lifted
Elevators
Elevators use linear motion to lift objects straight up
Step 3: Now let's check out some real scenarios where each lifting mechanism is used!
Elevator Lift
Linkages
Rotating Joint
Now that we know about appendages, object manipulation and lifting mechanisms, we can incorporate them into our robot designs!
