Hi, just search for differential drive info. Example: (the video is OK, but, it is kind of slow) [LINK] [this video] [LINK] If you are done with the theory , then, look at this package and to some of the projects that are using it: [LINK] There is a package that seems to be what you are asking for: [LINK] For learning the core of wheeled mobile robots I recommend you to read chapter 3 of this book: [LINK] BE AWARE : That Innok Robotics has actually two types of mobile robots ( [LINK] ), one is differential (Innok Heros 223) and the other one is an over-constrained mobile robot (Innok Heros 444) that is used mostly for outdoor purposes and "behaves" like a tank in terms of its way of turning (look

The robot you're trying to model is known as a Two Wheeled Differential Robot . It's easy to find specific kinematic models for it. You can start here [this video] or here [LINK] .

I am practicing C++ and intro to robotics using a simple differential drive robot and a raspberry pi. Also following along the GA Tech course [this video] on control of mobile robotics. The implementation I am trying firstly is the Proportional part of a PID controller for a Go-to-goal behavior robot, where I have a known state of [x , y , theta] and I have a desired [x_desired , y_desired , theta_desired] . Assuming a constant velocity, then the only control signal I can affect is the rotation rate omega, such that: error = theta_desired - theta; omega = PID(atan2(sin(e), cos(e))); // where Ki and Kd are zero Using a wheel encoder and basic odometry, I am able to calculate the distance traveled

I have been working on a line following robot for a line tracing competition. It has 7 IR sensors for line detection and the robot size is limited based on the competition rules. The robot structure is similar to the one shown in this question Length and Width of a Line Following Robot [LINK] . My questions is, given a fixed robot length and fixed distance between the wheels and the caster wheel, should be distance between the differential wheels be as big as possible or as small as possible, if there are sharp turns (90 degrees and more) in the competition map? I watched this youtube video Control of Mobile Robots- 2.2 Differential Drive Robots [this video] and it says the car turning speed is $
