2WD Smart Robot Car Kit with R3 Board, Ultrasonic Sensor, L298N Motor Driver, IR Remote Control, Obstacle Avoidance STEM Educational DIY Kit for Beginners

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.

So ya, for one thing it came with a press board frame instead of what's in the picture, still works ok but still. Another issue I'm worried about, my left tire refuses to rotate forward so I'm hoping it's not burnt out. I've read about burnt out components so hopefully that's not the issue. Simply it's ok. TEACHERS OF ANY KIND, don't get this. Hobbyists, you've been warned. Personally I'm blacklisting the company.

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.

Although the product description doesn't mention it, this product does not come with batteries and the special batteries it takes cost more than the robot car kit. See https://www.amazon.com/gp/product/B0GTPY263W. Build quality is fairly low, with screws that won't fit their holes, but probably acceptable at this low price point. The $25 battery is the killer for me and I'm returning it.

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

Trop facile a monter

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

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.
