4.2 Lidar Mapping and Navigation

The RPLIDAR A1 can generate a contour map of its surrounding environment by rotating its ranging core 360 degrees. This data is crucial for simultaneous localization and mapping (SLAM) and navigation tasks.

• 3D Visual Mapping: Create detailed 3D maps of the environment.
• Visual Navigation: Navigate through mapped environments using visual cues.
• Single-Point Navigation: Direct the robot to a specific point on the map.
• Multi-Point Navigation: Program the robot to follow a sequence of points.

4.3 Obstacle Avoidance and Tracking

• Lidar Avoiding: The Lidar detects obstacles in real-time, allowing the robot to navigate around them.
• Lidar Tracking: The robot can be programmed to follow a moving target using Lidar data.
• Lidar Guard: Set up virtual boundaries or detection zones for security or operational safety.

4.4 קאָנטראָל מעטהאָדס

• YahboomRobot APP (iOS/Android): Provides intuitive control options including gravity, key, and rocker modes, FPV video screen, speed adjustment, and light controls.
• ROS Robot APP (Android): Specifically designed for ROS robots, enabling map building, navigation, and image viewing.
• Jupyter Lab: אָפפערס web-page online programming control for advanced customization.
• ROS Control System: Utilize the full capabilities of ROS for complex control and automation.
• FPV Handle: For direct, real-time control of the robot.

4.5 אַוואַנסירטע פֿעיִקייטן
