Bill, I followed all three of you robot videos and have decided that this is the project that my grandson and I will do when he comes for a visit this summer.. Your videos are concise, clear and will be easy for him to follow I think it will be a big hit for him and maybe point him in the direction of electronics and/or programming.. thanks you.

Bill, you are amazing and awesome. Watched several of your videos and am truly impressed with your ability to present. But, I cannot even begin to imagine the time you spend on preparing these videos.The amount of time you spend on graphics, written materials and sketches is truly remarkable. Keep up the outstanding work, it has to be rewarding considering all the accolades you receive. Justly deserved. Thank you-your have a devoted follower. Bob

Good videos; bought the car. Made some code mods; The pivot turn used needs a higher speed to work on carpet. Lots of friction, initially just stalled out trying to turn, so added two different motor speed, one for moving forward and back and one for turns. Didn't like the pivot turn for remote control, so added a radius turn. Both sides motors run forward, outer faster than inner. Differential controls the radius. Swap motor speeds for left turn or right. Also found that initial collision avoidance distance was too short, adjusted out. Also different speed settings for forward/back and turns. Future mods; Collision avoidance, raise speed if long clear distance, reduce as shortens to stop. The ultrasound does not seem to get a correct distance from an angled surface. It seems to run into any wall that is at 45 degrees (about) to the direction of travel. Need a strategy to solve this problem (if possible). Possibly a 'stalled' detection. Want to incorporate both the radius turn and the pivot into the IR or bluetooth functions. Want to add a compass sensor and 'turn to north/south/east/west' options. Have a '3 axis magnetometer' on breadboard functioning to give a heading reading.

This has been a great project. A great job. My only problem is the Micro Servo 99 is I can't get a 180 degrees arc my best has been 15 -> 165 . When my kit comes in hopefully the servo will work better than the ones I've purchased. Thanks for a great presentation.
@user-um3ui1gu9t3 жыл бұрын
Some servos (most of the cheap servos...) turn only ~160°, not 180° ! That's the reason why in the example they used 20 to 180°

Thanks for the videos. When you show the code for the line following section, I'm a little confused when the pinmode is defined for the sensors. It seems like you are using the !digital read for the value of the pin in the pinmode command. or did I just miss something. Thanks again for the videos.

While line following, if you put a box on the line, will it avoid it? It seems like it's doing collision avoidance OR line following, but not both. Or am I mistaken?
@malinmalindic85824 жыл бұрын
What is rightDistance is equal leftDistance? So, in my opinion, after checking which distance is greater (or less) we should simple add else (which means they are equal) and in that block add commands back and delay, and checking if they are less or equal 20 should be separated if condition, but that only my opinion. Great video, thanks a lot.

Great set of videos! I purchased this kit for my son, we built it together but we were unable to make collision avoidance work as expected. I'm having the same problem described in comments. Apparently the ultrasonic works fine with flat surfaces, but not so much with irregular ones. While I debug the code with serial console the sketch works fine, but once in the floor the car doesn't seem to follow the right pattern. I noticed also that the following portion of code is "almost" never executed. It only works when right and left distances are equals and less than 20cm. else if((rightDistance

I thought you were going to fix the bad coding settings on avoidance. The stop and run after time is way way to high. This is why it crashes after stoping and turning. The servo turn, being 90 o and motor turn is not the same, it's about 45 o. If the case is,. Then a additional scan is required at 22 o As the scan time is set in 20ns, why there is a 1s wait I don't know,the most would. Be double the regent. Also we should ping and turn code. And I believe there is a mapping sketch? Hopefully so it learns the area.. it only needs to plot.

I really like your presentation and especially this series on the Elegoo car. The line following experiment was extremely interesting as well as being highly educational. Have you done any experiments on wire following, where the wire is excited by a sin wave signal and the car follows it? This would be useful in an environment where the ground is likely to become dirty and the black line is impractical.

Hi Bill, I am working on a project and I was wondering if you could help me. I got this Elegoo Smart Robot Car and a Pixy2.

So if you have any clue, on how to work this out please let me know, thanks.

Pixy2 has a tracked chassis from a company called Pololu if you buy the tank-chassis assembled all you have to do is mount the pixy2 camera and you can follow lines and objects like the Elegoo car. I have built both projects and they both work great at this task.

Another great video, thanks! During the collision-avoidance clip, the robot drove directly into a wall at one point. I have the same thing happen with a car I built using the same ultrasonic sensor. The sensor is seeing distances outside the stopping distance, so the car thinks it can go forward. This is probably due to the angle between the wall and the receiving part of the sensor. My question though, is how to avoid this? I can increase the distance to stop, but too far and the robot will stay in the center of a room. Do we just need to expect some collisions? Thanks!

u-sensor works really well with flat surfaces, but not so well with corners. You can also get negative distances as well as 2000+ distances..so you need to add more logic to deal with the variations and extremes you can get. Few things you can do: 1. only do something if the value is > 10 2. If the value is > 80, then set it to 80..basically u r telling the sensor to ignore anything far away...lastly...average several readings together after u do steps 1 and 2. facebook.com/keith.schaub.5/videos/10216652344993348/?l=9174098805765710842 facebook.com/keith.schaub.5/videos/10216597922712825/?l=1995439918924746601

in a nutshell, keep the USB connected and print out all the values in serial monitor while you manually move the car around - pay close attention to the values and think why might you be getting strange values and how to deal with them.

That code Elgoo provided is terrible! All does 500ms and 1s waits block processing. You should avoid blocking. And it’s simple just read time and see if 500ms has passed since your last measure meant. If not don’t execute, if it has execute. I see too much of this badly written code in arduino world. I don’t know where it comes from.

I install the program "Obstacle_Avoidance_Car" in the car, but the wheels on the right side don't move, only the wheels on the left side move, and both the distance meter and the servo work fine. After testing for several days trying to identify the cause, I found that if I delete the instruction "myservo.attach(3);" in the program, all the wheels and the distance meter work fine, but logically the servo is disconnected. Could anyone help me. I would like to know why this happens with that instruction? I want the program to work completely. I couldn't.
