Study Notes
Indicator Devices
- Indicator devices gather information about the robot's surroundings and internal state.
Sensors
- Detect various physical phenomena, such as light, sound, temperature, pressure, distance, and more.
- Act as the robot's "eyes and ears".
Vision Sensors
- Provide visual information about the environment.
- Enable object recognition, obstacle detection, and path planning.
- Examples: cameras, LiDAR, depth sensors.
Color Detector
- Uses a light-dependent resistor (LDR) array and LEDs of different colors.
- Identifies the dominant color when a light is shone on the array.
Line Follower
- Uses an infrared sensor array or a webcam.
- Teaches basic concepts of line detection and control.
Proximity Sensors
- Detect nearby objects using infrared, ultrasonic, or magnetic fields.
- Help robots avoid collisions and navigate tight spaces.
Obstacle Avoidance Robot
- Uses an ultrasonic sensor to detect obstacles.
- Programs the robot to turn or stop accordingly.
Distance Measurement Tool
- Uses an ultrasonic sensor to measure the distance to an object.
- Displays the distance on an LCD screen.
Touch Sensors
- Tactile sensors with pressure or force sensitivity.
- Allow robots to "feel" objects, enabling grasping, manipulation, and surface texture analysis.
