I participated in a Line Follower Competition held at university level among the college students. Got 3rd position there. All the participants who made this type of robot(this technique is called bang-bang) were eliminated in the first round or so. The only participants who could qualify for the semi finals made the pid line follower. Ours was pid too. But for this kind of robot, it requires a lot of precise calibration. It would be really good if you also try making an advance pid line follower that can be a competition winner.

This shows the difference between animals and plants or cells. Animals have brains, so they are like robots with microprocessors, but cells and plants don’t, so they are like this, using complex mechanisms to do somewhat simple tasks without thinking.

Nice project! I did a similar design last year, using two high brightness white LEDs for illumination, two yellow LEDs paired with an BC547 amplifying stage for each one for reflection detection (using the yellow LEDs as photocells), two BD135 with 1N4004 flyback diodes for driving the bigger motors and an LM339 for the comparator. I find remarkable that such a simple bang-bang controller can follow lines so well. But, I have to say that I've got VERY worried in seeing solder being filed. Most probably you are producing a lot of highly lead contaminated dust, because most popular solder alloys generally have 60% tin and 40% lead, or 63% tin and 37% lead. Not only it is very easy to breathe in some of that dust but, as well, this fine dust has quite an ability to stick to the skin of your hands, and stay there even after some washing. Play safe! Don't fool around with solder dust.
@MaxImagination

Thanks for your comment! Seems like there are many simple line follower robots of different kinds out there as such, cool! I see you got a point there with the solder dust, I will try not to touch it next time. Thanks for the tip. I've also already invested in a solder fume extractor to use every time I'm working on a circuit. I highly recommend it.

Really simplest design .. good for newcomers & beginners.. getting into it.. Here are some few points that you may consider in future attempts... The single led & ldr.., one for each side and the comparator mode of operation.. permits only a TWO LEVEL(binary/2 bit) control. With 2 per side , and the second pair , placed behind (or front) and slightly left/ (or right) of the first , will give a narrower band( configured like a hysteresis window) for each wheel.. Now you can get a minimum 4 bit logic resolution.. With additional combinational & sequential logic.. more permutation/ combinations properly worked out , can make it a more robust controller.. bear in mind this is just a " look down" decision controller.., and not a " look ahead" one.. In both cases.. the detect sensors & driven wheels are at extreme opposite ends .. Best would be to have idler wheels (turning L/R) controlled by this and rear wheels drive by some other circuit . Happy Tracking.. 😅

You can lower the gear ratio by using smaller rounded tires, you just may have to angle to motors to get them to touch the ground. Furthermore, you can adjust the steering effectiveness by making the front caster farther forward or backwards, and/or by bringing the wheels closer together or spreading them farther apart. To get max voltage drop to the motors, don't use Schottky diodes, but rather normal silicon diodes. Most Schottky diodes only drop ~0.3 volts. Normal silicon diodes drop ~0.65 V. You can also just use resistors if you observe ohms law. (same thing really.) Li-Po batteries can catch fire pretty easy. Recommend against their use if possible. At that size, it would be like a few books of matches going all at once. Still enough to burn you, or burn your house down. CdS photo cells are most sensitive to green light, right around 555nm. Use of a green LED and light absorber that takes green up best for your lines would be ideal. They make smaller dual comparator IC's. A reasonable substitute would be a dual op-amp IC.

Nice quick & simple basic tracker built & functional..... Its a simple dual " bang- bang" controller.... IMHO there are some minor improvements / circuit changes that could better its preformance.. 1) The single cable tie (clamper) on each motor cannot prevent motor pivoting during bang on / bang off....atleast use two ties..spaced further apart... 2) The LDR's should be moved closer to center of axis....it will reduce the off tracking error correction span. 3) Each LDR/& respective led must be gated/pulsed alternately to avoid each others light interfering on other sensor.....this means more electronics/ logic ckt.additions....😢 4) LDR axis & motors shaft axis..must be parallel to each other..... 5) try to obtain/make really well centered wheels.... 6) Wheels must be equidistant from pcb longitudinal axis centre.. 7) Wheels fitted with slightly tapered width..,with the smaller diameter on the outside ..will allow for natural correction to move in a straightline without " drifting " left or right on its own....... These are some mech. insghts I could offer..😅..wish you for best next attempt.

Great project!! The bot detects the difference between light and dark and correspondingly activates the motors but if both ldr are on white / black how does the opamp compare and subsequently send the logic to run both motors?
@MaxImagination
@MaxImagination 3 месяца назад
Thanks! If both sensors receive the same amount of light, the opamp makes the robot veer at random until it rolls over a contrasting color surface to continue differentiating.

I reckon you can simplify it down even further to just a single Op-Amp if you have it continuously running and have the op-amp push down a pin into the ground that allows the robot to turn around it to the left. Then when the pin is up, the robot will naturally swerve to the right. That way, the single op amp can be used as a switch.

I would like to add here.... With line detectors placed in the same axis as the front steering wheels (an additional pair here) {just as steering wheels are in present day multi- wheel system's} ,is really ideal... Also if the steering control is tweaked to output a behaviour as in "ACKERMANN STEERING SYSTEM's" or improvements in that..,then you have really nailed it. F.Y.I. ..ACKERMANN STEERING is the basis for all multi- axle vehicles..where the circle insribed by the turn of inner & outer wheels have the same center of their radaii & is always the midpont of the of the rear axis rear wheel dive pair.

Sure, learn more about the circuitry behind it described here: www.elektormagazine.com/labs/make-the-tiniest-line-follower-robot-without-a-microcontroller-1

I don't have the money, but I want to see it going 100mph on a straight line but, when almost at the end make a sharp left turn.

1 90 degree turn and it oes of track. wonder if i can add more of those sensor thingies.

Perhaps adding multiple photoresistors in a parallel array outwards like most of those competitive line followers would do the trick.

Simple question : Is it possible to make an invisible line with like some special pen and a special led ? Currently working on a huge racing circuit and i want so hard to add trafic without killing my budget.
@MaxImagination
@MaxImagination 3 месяца назад
Unless you're willing to change the photoresistors for magnetic reed switches, no. This isn't possible with the current robot setup due to the fact it needs to detect dark/light contrasting edges.

@@MaxImagination So let's say i use invisible magnetic paint and hall sensors on the device, it's possible ? Because a simple HO autonomous car is arround 150$ and it's pretty expensive.

That was really impressive! And using zipties with a perfboard like that was pretty clever. But gosh the editing of the intro felt weird

Thanks for your feedback. What part about the intro was it you found unusual?

I designed and built one of these (similar though larger) 60+ years ago using a total of FIVE (5) parts! 2 x CdS photoresistors, 2 X small DC motors, 1 X battery. Called it a robot Rat. It would turn to and run toward a flashlight. adding 2 X light sources and 2 lenses would make it a line follower! Mike L. "First MIKE on the internet - ca. 1975"

Thanks! This was when I was about 12 or 15 years old. I put it in a darkened "haunted House" and went exploring with a few kids with flashlights. It scared the c--p out of them! It ran towards the first kid to turn a flashlight on it, then turned to the next one to shine one to see what was happening. Mike L.@@MaxImagination

With sponsorship from PCBway, can you make a smaller version of this or the same size using only SMD parts?

Might try!
