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.

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.

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.

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.

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

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.

Buenas calidad de materiales y funcionó muy bien

El artículo me llegó en perfecto estado y en muy buen tiempo, gracias..

No con la calidad de otros que he adquirido pero es funcional. Me sirvió adquirirlo ya que me tope con varios retos que tuve que solucionar. No lo compre para mis sobrinos o sobrinas como muchos escriben, lo adquirí ya que doy clases de robótica y se me hizo un buen proyecto para mis alumnos, obvio que lo compre para saber si se los puedo dejar a mis alumnos que lo armen y pus no, la verdad esta un poco complicado de armar (físicamente) ya que los tonillos son muy pequeños y las tuercas pues mas, y si a mis alumnos se les caen tornillos y tuercas de 1/4 de pulgada y los pierden, pues imagínate lo que pasaría con estos. Pero bueno, como te decía SI debes tener muchas cosas en consideración para que funcione, DESVENTAJA: solo puedes programar un modo a la vez (evasor de obstáculos o control remoto infrarrojo), VENTAJA: es mas económico que los de la competencia y SI es funcional. Haaaa y debes ingeniártelas para armarlo correctamente ya que los diagramas de conexiones no corresponden a lo que esta en el programa de arduino. Finalmente te digo que NO es necesario que compres las pilas que recomienda el fabricante, puedes usar un portapilas para 4pilas AA con pilas y broche, o una pila cuadrada de 9V con broche.

Llegó en la fecha esperada, piezas pequeñas, producto completo, bien embalado
