Autonomous vs RC

RC robotics simply involves the use of a transmitter to send signals to a CPU that is dependent on constant human guidance and instruction.

Autonomous vs RC

Autonomous robots are robots that can perform continuous tasks without human intervention.

There are different degrees of autonomy. However,

fully autonomous robot can:1. Gain info about its environment2. Work for an extended period without human

intervention.3. Move either part or all of itself through it operating

environment without human assistance.4. Avoid situations that are harmful to people, property or

itself unless it is part of the design specifications.

VEX Robot Subsystems

The VEX robots can be divided into 7 subsystems:

1. Structure 2. Motion3. Power4. Sensor5. Control6. Logic7. Programming

1. Structure subsystem – consist of the parts of the robot that form the “skeleton” of the robot. Consists of all the metal components and hardware pieces. Together they make up the frame of the robot.

2. Motion subsystem – consists of all the parts that make the robot move. Consists of motors that generate motion and gears and wheels that transfer and transform the motion into different forms.

3. Power subsystem – required for the operation of the robot. It is the circulatory system that provides the robot with energy. Batteries and power packs are used in VEX robots.

4. Sensor subsystem – gives the robot the ability to detect things in its environment. They are the eyes and ears of the robot and allow the robot to function independently of human control.

5. Control subsystem – allow human operator to control robot. The transmitter sends sinals to the receiver of the robot.

6. Logic subsystem – the microcontroller. It coordinates and controls all other components of the robot. It is the robot brain.

7. Programming subsystem – a program that is the set of rules that tells the robot how to behave. Easy-C Pro.

Tasks

1. Inventory – create an inventory on your group laptop and subdivide the parts into subsystems. Submit for marks when complete.

2. Learning Journal a) Identify the function of each component in your

inventory. b) Give examples of how RC and automated

robotics are used in our community. 3. Read Inventors Guide on how subsystems

interact and take notes.
