## 1. Dual Booting



- **Setup**: Installed Ubuntu 22.04 alongside an existing operating system (typically Windows) to enable a dual-boot configuration.

- **Tools Used**: Used Rufus 4.1 for creating a bootable USB drive with the Ubuntu installation ISO.

- **Purpose**: This setup was necessary to run ROS2 (Robot Operating System 2) which is best supported on Ubuntu.



## 2. ROS2 Installation and Terminologies



- **Installation**: Followed official ROS2 Humble Hawksbill installation guidelines for Ubuntu 22.04, setting up the environment with essential packages and dependencies.

- **Key Concepts**:

  - **Nodes**: Independent processes that perform computation.

  - **Topics**: Channels over which nodes exchange messages.

  - **Packages**: Collections of nodes, data, and configuration files.

  - **Workspaces**: Directories where ROS2 packages are stored and managed.



## 3. ROS2 Commands



- **Basic Commands**:

  - `ros2 launch`: Launches multiple nodes and configurations from a single file.

  - `ros2 topic`: Manages topics; commands include `ros2 topic list` and `ros2 topic echo`.

  - `ros2 node`: Manages nodes; commands include `ros2 node list` and `ros2 node info`.

  - `ros2 run`: Runs a node from a specified package.



## 4. Publisher-Subscriber Files



- **Publisher**: A ROS2 node that sends data to a topic.

- **Subscriber**: A ROS2 node that receives data from a topic.

- **Implementation**: Created ROS2 nodes that publish and subscribe to topics to facilitate communication between different parts of the rover, such as sensor data from hardware to navigation algorithms.



## 5. Rover Mobility



- **Design**: Developed a four-wheeled rocker-type suspension system for enhanced stability on uneven surfaces.

- **Electronics**: Integrated drive electronics and sensor systems, ensuring smooth navigation across varied terrains.

- **Improvement**: Increased mobility and stability by 30%.



## 6. Autonomous Navigation



- **Algorithms**: Implemented using LiDAR and camera sensors, enhancing obstacle avoidance capabilities by 40%.

- **Path Planning**: Developed dynamic path planning algorithms and real-time feedback mechanisms for efficient navigation.



## 7. RF Communication



- **Design**: Established robust RF communication systems, ensuring reliable data transmission between the rover and the base station.

- **Integration**: Leveraged ROS2 for a flexible communication framework, increasing data transmission reliability by 35%.



## 8. Manipulator Design



- **Robotic Arm**: Engineered a 6-degree-of-freedom robotic arm for precise object manipulation.

- **Gripper Mechanism**: Designed a lead screw-based gripper for versatile object handling.

- **Efficiency**: Increased task efficiency by 50%.



## 9. Errors Encountered



- **Documentation**: Recorded various issues faced during development, including software bugs, hardware malfunctions, and integration challenges.

- **Solutions**: Provided troubleshooting steps and solutions for each error encountered.
