Freenove 4WD Smart Car Kit for Raspberry Pi 4 B 3 B+ B A+, Face Tracking, Line Tracking, Light Tracing, Obstacle Avoidance, Colorful Light, Ultrasonic Camera Servo Wireless RC
This little car has a lot going for it but mine had a couple of problems The well designed parts and 128 page instruction manual including the computer code make this car easy to assemble and operate. The ability to handle the testing of each module on a PC via RealVNC facilitates testing, and the phone app provides steering and speed control as well as control of the LED lights, camera and switching to other modes of operation. Tech support provides 24 hour responses via email and was very helpful for straightforward problems. All in all this kit offers a lot for the money and earns a five star rating.
However, I encountered a couple problems that should have been handled better and distracted from my overall enjoyment of the project. Next to control from a phone the most useful function is the obstacle avoidance using the ultrasonic sensor for control. The ultrasonic sensor that came with the car kit was defective and was replaced after three weeks for overseas shipping. However, the replacement sensor was also defective, and in spite of my detailed documentation of the problem Freenove refused to replace it. I had an ultrasonic sensor from another project which I was able to use but it had intermittent errors that severely compromised this important function. The other problem was less serious but annoying and time consuming. The code downloaded to control the car had an error which applied less than a third the required power to the wheels for forward motion. Therefore, the car refused to move resulting in several days of emails blaming the problem on the batteries before I finally traced it to the code error. It has been three weeks since this problem was reported to Freenove and a download of the code today showed the error had not been corrected.
Etwas für Fortgeschrittene und bedingt für Anfänge Ich nutze den Freenove Bot als Basis fr eigene Programmierungen. Da ich selber seit lngerem programmiere stellt das Gert keine Herausforderung fr mich dar. Fr Menschen ohne oder wenig Programmiererfahrung wird das schon schwieriger. Hier wrde ich eher auf deine Bot auf Arduino Basis verweisen. In der Arduino Umgebung findet man sich schneller zurecht und kann einfacher lernen.
Bei dem Raspberry muss man erst diesen einrichten, Software installieren, einen PC / Laptop fr den Remote Zugriff einrichten etc. Mit den vorgegebenen Funktionen kommt man schnell an das Ende des Spaes an. Das Teil ist gut geeignet wenn man selber programmieren mchte und schon ein Stck weit wei was man tut.
Zu FREENOVE selber.
In der Anleitung wird versprochen, dass man immer support bekommt und sich das Unternehmen auch ber den Verkauf hinaus verantwortlich fr seine Produkte sieht.
Ich kann das aus eigener Erfahrung nur besttigen. Ich hatte bereits mehrmals Kontakt zum support um auch tief gehende Fragen zur Elektronik zu stellen und bekam stets innerhalb kurzer Zeit Antwort.
Ich bin begeistert. Deshalb auch 5 Sterne Gesamtbewertung
Great fun assempling and learning Python for 12yo daughter. High quality produc The assembly instructions are pretty good but could do with a bit more clarity around the servo motors controlling the head. The code explanation are clear and very thorough.
The quality of the robot is higher than average but don’t forget you’ll need a Raspberry Pi tocomplete the kit – It’s designed for Pi v4 but, for those with a bit more knowledge, it can be powered by Pi Zero W if you can get one – they’re all still in short supply
All in all a great kit but would suggest minimum age is really 11/12
Könnte besser sei Es war “leicht” zusammen zu bauen. Aber 2 von die reder haben immer runtergefallen, musste ich ihn da kleben. Die sensoren die einte schwarze Linie folgen sollte funktionieren nicht mehr richtig nach 1 Tag. Vielleicht liegt es in die Programme. Es kann sich auf Laminat nicht so gut drehen. Einige funktionen “freeze” manschmal. Ich glaube die sind meistens programming Probleme die knnte viel besser sein. Musste die Buzzer ausschalten als er immer beept. Sonst macht spas fr so wenig geld.
It's a great learning tool. It can show you how to use your raspberry pi in practical engineering in your own home, learning to use the camera, line sensors, servos and motors. Just needs a bit of patience, and not get flustered with the tiny screws and nuts lol.
Fun kit, and super for a beginner. Liked the kit, but the instructions has some holes and the mobile apps required to control the model leavs a bit to wish for.
But over all it has potential and I will most definitely have fun with this one.
All the parts are there, well packed and easy to follow instructions, but a bit un clear at some parts.
Will get more kits.
And I’m planning to upgrade this one.
Overall the quality of some parts as you'd read in other reviews are not as good as expected. Especially the ultrasonic sensor holder and some of the wheels come out when turning, not a biggie, some things you can easily fix at home with glue or other stuff. I think the most valuable part of this robot is the tutorial and the amount of information you get, if you are new with programming or you are getting back to it, like me, it's worth every penny. Eventually, I bought some more sensors to keep digging into the programming world with Linux and Python. Overall the quality of some parts as you’d read in other reviews are not as good as expected.

I have been enjoying putting together this 4WD robot. It is so much fun to see something that I built come alive. I had an issue with one of the steps and emailed their support. On the same day (a Sunday no less!) their support sent me back email and got me up and running. I have been enjoying putting together this 4WD robot.

Great product, instructions can be a little unclea Works great and I think it’s a fantastic deal for it’s price. As long as you are technical minded and patient it’s fairly easy to assemble. There are some issues though. Attaching the head I had to use an extra nut to stop it from shaking. Sometimes the instructions are vague or repeat themselves. I also didn’t see anything about setting up face tracking in the tutorial. I also think the batteries should be included as they’re a little difficult to find.
Hervorragende Qualitä Das Fahrzeug hat viele vorprogrammierte Betriebsmodi. Nur die beiden Servos fr die Kamera sind etwas wackelig. Whrend der Fahrt zittert das Bild stark. Die Servos lassen sich aber durch solche mir Metallgetriebe fr eine bessere Stabilitt ersetzen.
Esperienza bellissima !!! Essendo sempre stato appassionato di informatica e programmazione, ho voluto anche avvicinarmi anche all’elettronica. Per farlo ho comprato un Raspeberry ed un kit, sempre di Freenove, ed a quel punto ho scoperto un mondo appassionante fatto si di elettronica, ma anche di sistemi operativi (Debian) e programmazione (Python). Ho quindi comprato questo kit e l’ho assemblato abbastanza facilmente pur non avendo una grande abilit manuale, darei solo il consiglio di aggiungerci anche minuteria di riserva, perdere qualche vitina facile. Finito il montaggio sono passato alla parte programmazione che assolutamente ben guidata e spiegata, ed veramente interessante e se ci sono dubbi il servizio di supporto risponde molto velocemente e risolve il problema. Concludendo, ora funziona tutto perfettamente, ma sto rivedendo i programmi per ampliare e migliorare le funzioni. Non vi dico che lo ricomprerei, vi dico che a brevissimo comprer il kit del cane.

The unit takes time to build so go slow when you are building. The customer support is excellent and will help you in every way possible to get things moving if you get stuck. Highly recommend.

Good Starter Projec Great tutorial and Video although they were not always in the same sequence. You need thin fingers and some non-metallic tweezers for some of the smaller screws.
5.0 out of 5 stars Great bit of kit to learn with This car is super easy to build and program, To be fair a lot of negative reviews around the fact you do need to by a Raspberry PI computer & 2 x 18650 batteries. But it does clearly state that fact.
After building the robot and configuring the pi following the online guide & videos on YouTube this robot car is up and running, IOS & Android compatible which is great. And just to ease the cost you can quite easily use a raspberry pi zero wh or zero 2 wh and the pi zero camera cable instead of a pi 4 which works the same, Tried and tested… The pi zero will reduce overall cost if you are on a budget. Recommended product for the cost… and the fun…
