Sensors
The Eyes and Ears of Robots
Sensors are the primary way robots perceive and understand their environment. They convert physical phenomena into electrical signals that the robot's brain can process.
Vision Sensors
Cameras and image sensors that allow robots to see and recognize objects
Examples:
Applications:
Object recognition, navigation, quality inspection
Proximity Sensors
Detect objects and obstacles in the robot's vicinity
Examples:
Applications:
Obstacle avoidance, distance measurement, safety systems
Touch Sensors
Detect physical contact and pressure
Examples:
Applications:
Grip control, safety, human-robot interaction
Motion Sensors
Measure acceleration, rotation, and orientation
Examples:
Applications:
Balance control, navigation, motion tracking
🤖 How It All Works Together
Sensors
Gather environmental data
Controller
Process and decide
Actuators
Execute movements
Power
Provide energy
🎯 Key Takeaways
Sensors are the foundation
Without good sensors, robots can't perceive their environment effectively
Power systems limit capabilities
The choice of power source affects size, weight, and operating time
Controllers coordinate everything
The brain processes sensor data and controls actuators
Actuators bring motion to life
They convert electrical signals into physical movement
