This is a high level instruction on how I should navigate a car in a known map with wheel encoders and an IMU. Please make it more detailed, down to what software and hardware I should use, how do I connect stuff, and the code/command prompt.

1. Create a map of the environment using a mapping tool such as GMapping or Cartographer.
2. Install wheel encoders on the robot's wheels to measure the distance traveled.
3. Install an IMU on the robot to measure the robot's orientation and angular velocity.
4. Use the wheel encoders and IMU to estimate the robot's position and orientation relative to its starting position.
5. Use the map to plan a path for the robot to follow.
6. Use a path-following algorithm such as PID control to control the robot's motion along the planned path.
7. Repeat steps 4-6 as the robot moves through the environment

In order to navigate a car in a known map using wheel encoders and an IMU, follow these detailed steps:

Hardware Requirements:

1. A mobile robot platform (e.g. a 4-wheeled robot), capable of moving and turning.
2. Wheel encoders for measuring wheel rotation.
3. An Inertial Measurement Unit (IMU) for measuring robot orientation and angular velocity.
4. A LiDAR laser-range finder or depth camera for mapping and localization.
5. A microcontroller or single-board computer, e.g. Raspberry Pi, Arduino, or similar device.

Software Requirements:

1. Robot Operating System (ROS) or ROS2 for managing the robot's components and software stack.
2. SLAM (Simultaneous Localization and Mapping) tools like GMapping or Cartographer for creating the environment map.
3. A path-planning algorithm (e.g. A*, Dijkstra, or RRT) for planning a path for the robot.
4. A path-following algorithm, such as a PID controller or Pure Pursuit.

Procedure:

1. Assemble the robot hardware:
   a. Mount the LiDAR or depth camera on the robot.
   b. Attach the wheel encoders to the robot's wheels.
   c. Connect the IMU to the robot's structure.
   d. Link all sensors and controllers to the microcontroller or single-board computer.

2. Install Robot Operating System (ROS) or ROS2 on the single-board computer or microcontroller.

3. Create a map of the environment:
   a. Set up your chosen mapping tool (GMapping or Cartographer) and configure it in ROS/ROS2.
   b. Drive the robot around the environment, while the mapping tool records data from the LiDAR or depth camera.
   c. Save the generated map for future use.

4. Install the wheel encoders and IMU in the ROS/ROS2 software stack:
   a. Configure the wheel encoder nodes in ROS/ROS2 to subscribe to the wheel encoder data.
   b. Configure the IMU node in ROS/ROS2 to subscribe to the IMU data.

5. Write a custom ROS/ROS2 node to use the wheel encoder and IMU data to estimate the robot's position and orientation, relative to its starting position. Apply
