LAFVIN Smart Robot Car 2WD Chassis Kit with Ultrasonic Module R3 Board,Remote Compatible with Arduino IDE DIY Kit

El producto llego completo, funciona muy bien, facil de armar aunque se puede mejorar las instrucciones de armado, hay que revisar el manual en la lección 8, ya que el circuito de conexionado no es compatible con la programación, cuando lo probe solo arrancaba un motor y pensé que venia dañado, pero después de revisar las salidas digitales del programa eran diferentes a la del conexionado, simplemente cambie como esta en el programa y funciono.

The pictures are a perfect reflection of the parts received. Also the after sales support of the supplier was prompt and efficient. This being my first build, the instructions were sufficiently comprehensive to get started. Only negative is that the non-standard batteries are not included.

Well I did it. I built this stupid kit in spite of the instructions. They will be your biggest obstacle. All of the parts are there and the instructions are there but they stink and are illogically arranged almost like a wiki someone gpted together. Mine worked once. It woke up scanned the room and moved forward. it then scanned again and immediately scooted at top speed and repeatedly rammed itself into the wall to death. The Arduino is burned out on the pins going to the motor board. I rebuilt it twice to be sure nothing was wrong. I even tried another real Arduino to make sure and nothing. It just sits there. It was a complete waste of time and effort. I am a fool.

I received the Lafvin robot car a few days ago and started putting it together. The instructions are a little weak for a first time builder, but usable. For the $, they can't be beat. My biggest disappointment was that the kit is made for a pair of 18350 cells, which are not all that standard in the US. I replaced it with a 6-AA cell battery box from Amazon. I've built 2 other VKMaker cars, which had basically the same components, but much poorer instructions and no usable code(I had to find the code from links in the Questions section). As I was playing with this kit, I did the Ultrasonic Sensor lesson. The code worked perfectly, as did the code for the final, ultrasonic sensor version of the car. So far I have not tried the Remote Control version. I will update when I do.

Instructions are not clear.My unit had a faulty ir transmitter I had to replace.The obstacle avoidance works if you stick it in a box as in the demo video but in a room full of furniture it's not going to work.Never got the ir to work consistently,would start but not turn off nor turn left or right.If you are buying this kit for a child I'd spend more money and look elsewhere.

It was fun to assemble the wiring took some work to wire it you will need a basic understanding about arduino the IR code dissent work though but the auto works and it's fun altogether

So many problems with this kit.I've built several other robot cars from China, so I wasn't expecting super easy to follow directions, but this one was really bad.No clear wiring diagram in the whole set of instructions. Many of the instructions refer to a 4 wheel version of this kit. There's different lessons for the IR sensor, wheels, ultrasonic sensor. They reuse pins across the different lessons, so it's not possible to have the code for the ultrasonic sensor work at the same time as the IR.The UNO board included didn't work.No batteries are included, which I knew from the description.The included remote doesn't contain a battery.The design of the robot is poor. The IR sensor faces forward, so you can only control the robot while it's coming toward you.I guess I'm going to part this out and build something else. Do not recommend. The Elegoo smart car was much much better.

Fun to build. Wish it would have said it the description that it does not come with the 3.7v 18650 batteries. Trying to rig up a power source until the batteries I had to order get here.
