Understanding Autonomous Systems
Within the world of smart tech, autonomous systems are different from automated systems. Automated systems do well with set tasks but can’t adjust to new or changing conditions. Autonomous systems use machine learning and artificial intelligence to do things in the real world. They make their own choices and adapt to changes.
Distinction from Automated Systems
The big difference between autonomous and automated systems is their independence. Automated ones are great at their tasks but can’t think outside their programming. Autonomous systems can understand their surroundings, learn, and make smart moves all on their own.
In tricky and unpredictable situations like city driving or exploring rough lands, autonomy really shines. Self-driving vehicles and robotic explorers need to make quick decisions. Automated systems just can’t handle this kind of variety, while autonomous systems thrive.
Human-Inspired Intelligence
The design of autonomous systems takes from the incredible decision-making of our brains. In artificial intelligence, experts are trying to match or even beat human thinking. They use advanced algorithms and networks to teach machines to think, learn, and decide.
This thinking, inspired by humans, allows autonomous systems to handle complex places, deal with surprises, and solve tough problems. As tech grows, adding machine learning and artificial intelligence to these systems promises new ways to innovate and solve challenges.
Autonomous Systems in Exploration
The DARPA Subterranean Challenge showed a big need for useful path planning and SLAM for autonomous robots. They explore hard-to-reach places like mines. These spots are tough because GPS is not always available. They have dangers, tricky terrain, and sensors can’t work well because of dust or fog.
Challenges in Tunnel Navigation
Tunnels and underground places are hard for robotic exploration. Creating new algorithms for path planning is key. These help make sure maps are right and the robot is safe. SLAM and path planning are very important. They make it possible for robots to work well even without GPS.
Look at this table. It underlines why it’s vital for robots to make their own decisions in space. It also shows some of the tough jobs they have to do:
| Scenario | Challenge | Solution |
|---|---|---|
| Long-distance Space Missions | Round-trip communication delays between Earth and Mars can be as long as 42 minutes. | Onboard autonomous decision-making for time-critical control. |
| Crewed Spacecraft Operations | Long-term crewed spacecraft like the International Space Station require significant real-time support from Earth. | Autonomous systems to handle complex space operations. |
| Machine Learning Hardware | Energy expenditure per operation and throughput acceleration metrics are crucial for neural network accelerators and neuromorphic computing in space. | Efficient hardware for onboard machine learning capabilities. |
| Cave Exploration | Challenging environments like caves require robust and coordinated control and data collection strategies. | Swarms of space vehicles for dispersed but coordinated exploration. |
| Fault Management | Space missions demand autonomous recovery from anomalies and faults to ensure mission continuity. | Advancing fault management technology across various mission phases. |
The Lunar Orbital Platform-Gateway aims to use artificial intelligence and machine learning to help in space for a long time. They also work on making sure future Mars missions are ready. Groups of space vehicles help a lot with collecting data and working well together in space.
Autonomous Robotic Mapping and Navigation
In the world of autonomous robotic mapping and navigation, experts work on high-tech systems. These help robots move and chart out tricky places well. An example is LAMP 2.0, which is excellent for big underground areas.
LAMP 2.0: Multi-Robot SLAM System
LAMP 2.0 has a special feature for finding loops and another for making routes better. It can even work with different types of movement and sensing data. This corrects errors and improves the view, making sure robots find their way and map spaces correctly. Many tests show that LAMP 2.0 works great in the real world, helping with big mapping tasks.
Path Planning and Frontier Exploration
Researchers are also making systems for autonomous mapping and exploration using drones. These systems use smart ways to explore new places, like advanced math and special plans to move. With these tools, drones can move and chart areas that are too dangerous or hard for people to go.
| Algorithm | Description | Application |
|---|---|---|
| A* Path Planning | Finds the shortest path between two points while avoiding obstacles | Robot navigation in cluttered environments |
| Dynamic Window Approach | Generates kinematically feasible trajectories based on current velocity and constraints | UAV navigation in dynamic environments |
| Frontier-based Exploration | Identifies and prioritizes unexplored areas based on sensor data | Mapping and exploration of unknown environments |
With such advanced tools and smart plans, researchers are making robots explore and map complex spaces better. This leads to new ways of using robots in many areas.
Autonomous Systems in GPS-Denied Environments
In the modern world, being able to find your way without GPS is more and more important. In places like mines, dense forests, and city canyons, GPS often doesn’t work well. To deal with this, experts are coming up with new ways for machines to explore these tough spots.
One method uses something called Partially Observable Markov Decision Processes (POMDP). This lets unmanned aerial vehicles (UAVs) move around without GPS, in places like mines or dense forests. It combines a few technologies like simultaneous localization and mapping (SLAM), visual odometry, and POMDP. These help the drones make smart decisions on their own, without human control.
Draper has shown that drones can be very smart and move on their own even without a lot of tech. They use a small, simple processor, and just an IMU and a single camera. This means drones can avoid obstacles well and make their own 3D maps, helping soldiers think less about flying them.
Draper’s software can work on little drones you can hold in your hand. But it can also fit on bigger drones or smart vehicles. This makes all kinds of machines more able to do new tasks all by themselves.
| Statistic | Value |
|---|---|
| Percentage of widely deployed autonomous systems relying on GNSS | Majority |
| Percentage of GNSS signal blockage affecting autonomous systems | Very susceptible |
| Percentage of environments where GNSS signals cannot be reliably used | Indoors, urban canyons, densely forested areas |
Draper is making robots and drones that work together better through a project called CSIRP. They are adding new AI to the drones so they can work in complicated 3D spaces. They are also improving how they test and include new tech in these machines.
- The autonomy software made by Draper can work in tough places where GPS doesn’t work well.
- This software helps make ordinary vehicles better at working alone in new ways.
Simultaneous Localization and Mapping (SLAM)
Simultaneous Localization and Mapping (SLAM) is a new tech letting robots find their way and map out spaces. Imagine a robot finding its way in a changing area by itself. This tech is key for robots to work on their own in different places.
The RHINO Autonomous Robot
The RHINO robot shows how SLAM works without relying on GPS. It explores mines with LiDAR and IMU tech. Thanks to the LIO-SAM system, RHINO makes detailed 3D maps while moving through tough spots.
RHINO is built to work on its own thanks to its advanced features. It uses many technologies to navigate tough terrains. It proves how SLAM can help robots deal with real challenges, leading to better robots in the future.
SLAM Techniques
There are many methods in the SLAM field, each suited for different needs. Some of these include:
- Monocular Visual SLAM: Uses just one camera.
- Stereo Visual SLAM: Uses two cameras for better depth awareness.
- RGB-D SLAM: Joins color and depth data for clearer maps.
- LiDAR SLAM: Uses LiDAR sensors for highly detailed maps.
- Visual-Inertial SLAM: Mixes visual and motion data for mapping.
Each method works well in certain places. For example, visual SLAM is great indoors, while LiDAR SLAM is best for outside areas.
Path Planning and Mapping
Path planning helps robots move autonomously. It uses maps from SLAM to find the best routes, avoiding obstacles and meeting goals.
Algorithms like A* and RRT help with path planning. Others, like LOAM and FGR, make laser data better for use in maps.
Calibration in Unstructured Environments
Understanding how to extrinsically calibrate a camera-LiDAR sensor fusion system is key in autonomous navigation. The paper with the Digital Object Identifier 10.1109/ACCESS.2020.3014121 introduces a new targetless calibration method. It’s designed for unstructured environments.
This method is able to accurately estimate the six-degree-of-freedom (6-DOF) transformation between cameras and LiDAR. It uses a special technique that looks at local edge features in arbitrary environments. This calculation helps in sensor calibration by measuring 3D-to-2D errors.
The Perspective-three-point (P3P) algorithm finds the best way to calibrate. A Kalman Filter is then used to make the calibration more stable in the presence of noise. Importantly, this targetless calibration method works without needing any special targets or structured areas. This makes it ideal for unstructured environments.
This method described in the article also doesn’t rely on having a lot of points in the cloud, which lessens the need for lots of scanning. The research proves the calibration is both accurate and strong against noise based on the Kitti dataset tests.
