LAFVINSmart 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.

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.

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.

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.

Ok price if you just want parts. Not a good kit. Batteries are odd type and have to be ordered. Batteries don’t fit in the battery case provided. Manual for the obstacle avoidance is incorrect and you have to look at the program to figure out the proper pin outs.

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
