Yes, you are right, but the problem is what is the method to get good value for P, I and D.

Sorry, I don't understand.

Thank you. I've always thought that the fewer lines of code, the more readable it is. It is for this reason that when several instructions relate to the same objective, I group them together on the same line. When all the whole code fits on the screen, I'm very happy. This way is considered heretical, but I will not change it. Unfortunately, this is not possible with Python. Pity.

In this video I show how to program the real 360° Gray GeekServo. This video is not sponsored.

The code is 30 lines long. You can see it at 1'53". The link is on description, but here it is, https://github.com/oracid/Chariot-Robot-HuskyLens-Line-Follower-with-PID/blob/main/Chariot-LINE_TRACKING-V4-ref.ino Thank you, but I should work still a little bit.

In this new video, I show a Robot Chariot with the HuskyLens AI camera following a line. Here the speed is greater than with a tank and a PID shows its efficiency. As usual, I associated Lego, Arduino and servo RC technology. This association allows achievements without constraints and without limits.

In this video, I show how to follow a line as closely as possible. The idea is to continue the current bend, but that doesn't work with a right angle, to the left, when you have just turned right.

Here is a new app for my Mini Tank. This is a line follower with a HuskyLens. I skipped the PID, I did my own thing and in the end with less than 25 lines of code, I'm not unhappy with the result. Hope you like it.

Thank you. The Geekservo are in different versions : - grays are ordinary servos with a range of 0 ° to 180 ° - greens are servos with continuous rotations with a reduction of 1/140, 160rpm. - blues are continuous rotation servos with a reduction of 1/300, 90rpm. - reds are DC motors, not servos. The set operates from 4.8V to 6V Here are some links: https://fr.aliexpress.com/item/1005003469259929.html?spm=a2g0o.productlist.0.0.79166596yg1y1n&algo_pvid=8a229cfb-707b-4e9e-ad96-ac3152bd5fc9&algo_exp_id=8a229cfb-707b-4e9e-ad96-ac3152bd5fc9-11&pdp_ext_f={"sku_id"%3A"12000025926811754"}&pdp_pi=-1%3B83.06%3B-1%3BEUR+51.48%40salePrice%3BEUR%3Bsearch-mainSearch https://fr.aliexpress.com/item/1005003078987958.html?spm=a2g0o.productlist.0.0.79166596yg1y1n&algo_pvid=8a229cfb-707b-4e9e-ad96-ac3152bd5fc9&algo_exp_id=8a229cfb-707b-4e9e-ad96-ac3152bd5fc9-6&pdp_ext_f={"sku_id"%3A"12000023925828260"}&pdp_pi=-1%3B82.72%3B-1%3BEUR+51.48%40salePrice%3BEUR%3Bsearch-mainSearch https://fr.aliexpress.com/item/1005001419298190.html?spm=a2g0o.productlist.0.0.79166596yg1y1n&algo_pvid=8a229cfb-707b-4e9e-ad96-ac3152bd5fc9&algo_exp_id=8a229cfb-707b-4e9e-ad96-ac3152bd5fc9-2&pdp_ext_f={"sku_id"%3A"12000016028199434"}&pdp_pi=-1%3B77.66%3B-1%3BEUR+51.48%40salePrice%3BEUR%3Bsearch-mainSearch https://fr.aliexpress.com/item/1005003469180567.html?spm=a2g0o.productlist.0.0.79166596yg1y1n&algo_pvid=8a229cfb-707b-4e9e-ad96-ac3152bd5fc9&algo_exp_id=8a229cfb-707b-4e9e-ad96-ac3152bd5fc9-13&pdp_ext_f={"sku_id"%3A"12000025926228938"}&pdp_pi=-1%3B82.78%3B-1%3BEUR+51.48%40salePrice%3BEUR%3Bsearch-mainSearch

Thanks to the new Lego compatible Geekservo, it is now within everyone's reach to make a small crawler robot in less than one hour. With these radio control servos, the association with Lego mechanics and an Arduino board is very simple. I wanted to develop, here, a radio control application to make this Mini Tank more attractive. Keep in mind that the range of such a radio controller is 500m to 1000m. As usual, the program is extremely simple, even simplistic.

Happy New Year everyone. May the force of the Lego be with you, and stay safe.

Very interesting ! I am just making a small tank with these servo and an Arduino Nano. I hope to be able to guide him with a remote control.

In this video, I test the influence of rubber bands in a Diamond 5 Bar linkage. The rubber bands compense the weight of quadruped. The goal is to use less powerful and lighter servos.

The 32556 or the 3673 is not elastic in the center because they are not cuted. As a result, even though I don't have this piece you show me, I doubt its action. One of the advantages of pine 2780 is that it is cut in the center, this makes it elastic. @gyenesvi, Unfortunately the pin axle 3549 is not usable in all situations. Thank's all.

Here is a type of video that is unusual for me. I had so much trouble with the play of the pins that I have wanted to wring my neck out with this problem.

You are right ! But the RP2040 is a RaspBerry PI, but not a PC. Here, the Arduino Nano RP2040, https://store.arduino.cc/products/arduino-nano-rp2040-connect?_gl=1*y305oh*_ga*MzYyMTI3NDg0LjE2MzQ0NjA5MTk.*_ga_NEXN8H46L5*MTYzNTAwODM0Mi4zLjEuMTYzNTAwODQxNi4w

32 bit microcontrollers are certainly very interesting, but to activate motors the speed of execution is not that important and with a simple 8 bit such as the Arduino Nano and a Shield of connections. I think I have shown that without soldering and without any knowledge in electronics, we can achieve quite interesting things, even ambitious.

Well, if you have a Robot Inventor Mindstorms, you can use only 4 motors. Refering to this 2 videos, you can do it :

Nobel Prize ! "What else ?" Thank you.

This is my new video. A 12 DOF (Degrees Of Freedom) quadruped was a challenge for me. It's done !

Thank you for sharing this great work.

This is a very good alternative of omni wheel ! It goes front/back and left/right whose are 90°. But does it goes front/right ? I mean 45°.

In this video, you can see the new version of my 5 bars with extension quadruped robot. In this new version, le leg is thinner thus the connection between the servo arm and the leg is contiguous. And the main axis of the 5 bars has been raised by 1L. All this gives a more simpler and realistic look than the previous version. https://www.eurobricks.com/forum/index.php?/forums/topic/185173-5bq-e-5-bars-quadruped-with-extension/

Here are the mounting instructions for this quadruped.

In this new video, I show that a 5 bars linkage is similar at a 5 bars linkage with extension. With this linkage, my new quadruped is more like in the real life. Thank you in advance for your feedback.
