Mechanical
Friction is a force that resists motion when objects rub against each other.
Center of gravity is the place on an object where the weight is evenly distributed and everything is balanced.
Robots need friction to drive properly, and center of gravity keeps the robot balanced.
A Mechanical Advantage is the calculation of how much faster and easier a machine makes your system.
Sensors
Bumper sensors, also known as touch sensors, sense physical touch to help a robot avoid obstacles.
Distance sensors measure the distance to an object, the size of the object, and how fast you are approaching.
