Chapter Content
- Applications in grading and leveling
- Automatic blade control using GPS
- Terrain mapping and obstacle detection
Detailed Explanation
Autonomous bulldozers are designed to perform tasks like grading and leveling on construction sites without human intervention. They use GPS technology to control the blade automatically, ensuring precise earth-moving operations. Additionally, these bulldozers can map the terrain and detect obstacles in their path using various sensors, allowing them to navigate complex environments safely.
Examples & Analogies
Imagine a smart robot car that can drive itself through a busy city. Just like this car uses GPS to find the best route, an autonomous bulldozer uses GPS to manage grading on a construction site. It can even 'see' if there are rocks or debris on its path and avoid them, ensuring that the site remains safe and the project stays on schedule.
