Freenove 4WD Car Kit (Compatible with Arduino IDE), Line Tracking, Obstacle Avoidance, Wireless Control App, Ultrasonic Sensor Motor Servo

Too easy to assemble, wheels loose in some maneuvers and never work properly. After many tries with support team, it was not capable to use iPhone controls, follow me sensor, lights and chime. Only work with remote control. Lost of money and time.

Great educational kit

I used this robot car for a K-12 robotics class with ~20 students. Two cars of ~20 have broken Arduino boards. I did a careful check and found that their bootloaders were not properly flashed. I tried to re-flash through ISP but failed. There is still hardware issue, and Arduino ISP cannot identify this board's electronic signature. In addition, the line track module exhibits a very poor color selectivity/sensitivity. Usually, for other similar robot car models, they provide a variable resistor for each infrared detector, which could be used for adjusting the sensitivity. However, Freenove cars do not have this option. The temporary solution is to move the tracking module out of the fixing location and place it in front of the car and reduce the distance to the surface. In this way, the sensitivity is temporarily acceptable, avoiding to completely screw up my class. Also, I need to point out that the adhesion between wheels and motor rods is weak, and the wheels keep falling off. My suggestion is to drill a 2mm hole at the center of the wheel and use a screw to fasten the wheel on the motor rod. Finally, I don't like the design of the expansion board, which does not provide additional JR-format pins for DIY projects. Elegoo's design is more suitable for DIY projects and extensions.A positive feature: The speed of the Freenove car is really fast and suitable for FPV games.

Great robot car, easy to follow assembling instructions. I ran into a program issue and emailed the support and they replied to me withing 1 day. Very clear and excellent support!

I started with programming and wanted to further it into physical projects. This was a great intro and learn the basics. Only thing I didn't like was some screw connections aren't aligned perfectly and some really hard to get in with basic tools.

es muy complejo pero es super me encanta

DO NOT buy this product, unless you want to deal with frustration and things not working. Absolute waste of money and time.

un excellent kit de découverte de la programmation pour les ados

El envío llego rápido y sin problemas.El producto viene en una caja, con todos los componentes, perfectamente ordenados e identificados, en varios embalajes y bolsas individuales, así como unas pequeñas herramientas que facilitar el montaje.El código viene muy detallado en el tutorial en formato .pdf, y siguiendo las indicaciones de los diferentes vídeos de Internet, se monta muy fácilmente.Para su correcto funcionamiento, hay que utilizar las versiones de las librerías que acompañan al fichero .zip, que hay que descargarse desde la página oficial, y sustituir aquellas que no se correspondan en el IDE de Arduino.

Adecuado para los proyectos escolares.

Missing pieces,Very unorganized tutorial and files were messy.Some parts seemed used.Some screws were broken and the tools also were not fully functional.

Ottimo kit con tutorial annesso sia per quanto riguarda il montaggio fisico dell'auto, che per quanto riguarda il codice: viene spiegato in Italiano step by step implementando una funzionalità per volta. Utile sia per principianti neofiti che per i più esperti.
