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

Good fit the most part but some of the instructions are hard to follow. Good fit a project but helps if you have done something like this before.

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.

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.

Came with everything listed and worked when assembled. Finding the specific car on their website was a little difficult but the wiring diagrams and provided code were sufficient. Needed this for a school project so can't beat the price for what you get. Quality was decent and got the job done. It need 18650 batteries which are not cheap at most places.

I've had an awful customer service experience with LAFVIN over this kit. I needed the arduino to work in this kit so that i could complete a lab for school. I tried to email them and they quickly just shoot me down and tell me to download drivers, after I know for a fact it is not. Overall, this product had many cheap parts. I had to solder the negative back onto the battery case, and the wires easily fall out of the motor controller. The directions on assembling are lackluster, and i found myself questioning design choices. I would not recommend LAFVIN for the customer service aspect alone. Don't expect help from them if something doesn't work.

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

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.

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.
