The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Tips on where to start with modelling and control of a manipulator?
I recommend starting with the CAD model of the manipulator and then using it to generate the URDF (there is a plugin for that). This will enable you to visualize and simulate it in Gazebo and make the motion planning with moveit. I even started from before that and built a simple RRR arm from scratch here. I made it without CAD, but the reason was that I wanted to understand the internals. I used moveit here for planning with collision avoidance. There are steps to generate moveit config package for your robot in the same link.

How to control a 4 wheeled robot with ROS?
Either use this node, or take a good look at it and make a variant if it needs changes. https://github.com/ros-controls/ros_controllers/blob/noetic-devel/diff_drive_controller/src/diff_drive_controller.cpp

I don't think my calculations are accurate. Care to chime in?
Here's the code and the equations are found on line 491 and 492.

RC Car / Chassis - Location Tracking via wheels
You can check this repo for inspiration https://github.com/ros-controls/ros_controllers/tree/noetic-devel/ackermann_steering_controller as it implements odometry for robots with Ackermann steering. But it doesn't translate angular velocity into steering angle (I'm working on it in my own project).

What are some alternatives?
When comparing rrr_arm_config and ros_controllers you can also consider the following projects:
rrr-arm - ROS package for 3 DOF Revolute-Revolute-Revolute robot arm built from scratch using xacro model. The developed robot is visualized in Rviz, and simulated in Gazebo simulator. MoveIt config package for the robot is developed and interfaced with Gazebo (find the link at the end of the page).
ros_diffdrive_robot - Arduino code to control a differential drive robot via ROS Twist messages using a NodeMcu or ESP8266
