Hi Leppoldo, there is a mistake in slide at 10:41, VR and VL in the picture on the left are reversed. anyway, your channel is the best. BTW. you should add the link how to buy you solution in every video, otherwise, it's easy to ignore.Your solution is worth the money😀
Hello Leopoldo, thank you for doing all these tutorials. It's been super helpful so far. Furthermore, could you do me a favor and provide the complete child script? I dont really get it done successful and I want to see my errors. Thanks =)!
Himanshu Dubara There’s a kinematic relation between the wheels. So you can set the angle and the velocity of the ‘third wheel’ as if it a car-like robot to compute the velocities of the rear wheels, assuming there’s no wheel slippage. On the other hand, there’s a technique known as pure pursuit that basically gives you the geometric expressions to compute the wheel angle to converge to a line for a given distance. Based on this technique I derived the expression indicated in the video. At this point of the tutorial this is something off-topic that I prefer not to mention in detail to keep the video as short as possible. So that’s why I provided with the formula, but without too much details on how I’ve got that formula.

Hey Leopoldo, I bought the DYOR Solutions and I replicated this system using python but had difficulties with communication with Coppeliasim. I used Spyder to run it and it run just once and stops. Please, is there a way to solve this?
Hello, I’m not sure what’s the problem. Have you tried to run any other code, just to check that your Python-CoppeliaSim connection is working as expected?
There's a type in function "getDistance". It should accept two input arguments as shown:
function getDistance(sensor,max_dist)
…
end

Thanks for your comments, I really appreciate them. In the picture, the robot points mostly upwards, so it is correct

hello sir i am big fan of you. I have a question i want to read the angle of the firs detecte object by proximity sensor. Can ı do this ?
Sir can you explain how you arrived at third wheel angle and velocity of each wheel?

Do we have to associate this code to the proximity sensor or the robot base?
Hello, to the robot base
@@LeoArmesto thank you sir
Hello Sir,
Where should we add the condition to calculate the speed of the wheels?
Usually inside ‘SysCall_actuation’ function you need to compute the wheels velocity

You haven’t define the value of ‘dist’ before using it
@@LeoArmesto I have assigned dist=getDistance(sonar,max_dist) under Syscall_sensing
Its working now. Thank you!

@@LeoArmesto I finally found the problem. I needed to use a while loop. Thanks for th reply
