Issues and comments so far: 1) The plastic pieces are laser-cut out of acrylic and have a protective adhesive paper on both sides that you will want to peel off (unless you like the look of that over the clear plastic) 2) The manual calls for M3*8mm screws to attach the motor driver board to the baseplate, but the kit included M3*6mm screws (correct according to the label in the bag) which are too short to reach through the 1/4" acrylic baseplate. This required a trip to Home Depot to acquire some M3*10 screws (Hint: they store the metric screws in drawers way down the aisle from the rest of the machine screws) which work but are *almost* too long. You just need four of them as the 6mm screws work fine for mounting the Arduino on the thinner upper deck. 3) There is one acrylic piece with a right-angle bend used to mount the ultrasonic transducer. This is made by laser-cutting a flat part and then heating and bending the end, likely by hand. In my case, the bend is less than 90 degrees and will result in the transducer pointing down at the floor without some kind of shim or other adaptation. I ended up only installing the two bottom spacers and gently tightening the nuts which gave it just the right level of upward angle to compensate. 4) As all the other reviews correctly point out, the system is powered by two 18650 batteries but no way to charge them is provided and most people will need to acquire a separate charger (that will probably cost more than half what the entire kit costs). It should be clearly stated in the product description that everything you need is not in fact included. 5) The connection of the ultrasonic transducer assemby to the servo is not illustrated and is fiddly. You need to attach the servo arm that comes with the servo to the servo FIRST (it won't fit through the middle hole in the tranducer assembly tab) with the small screw incuded with the servo arms. Then they want you to use the servo mounting screws to attach the acrylic bent tab of the assembly to the servo arm, which requires you to use only the outer holes to avoid hitting the servo, and those screws are way to big for this and do not align well with the holes in the servo arm. 6) The assembly instructions really don't touch on wiring everything together, and have you mount the top deck before getting into the experiments where they talk about wiring the motor driver board which is between the two decks and not possible to wire with the top deck installed. 7) There are specific experiements and code for operating each of the sensors etc. separately, but most of these do not involve the car actually being driven. It's not yet clear if there will be enough storage to load all the required drivers to operate everything together. There's only one complete robot experiment provided which is a line following application. You're pretty much on your own to do anything cool like using the servo and ultrasonic transducer to scan the area in front and choose a path say. 8) While there are four motors, one for each wheel, the motor driver board only has two outputs in differential (+/- bidirectional) drive mode so the two left motors are wired together and the two right motors are wired together. I'll update as I make further progress. Otherwise, it's a great kit due to the large number of components you get. The UNO 3 compatible, the sensor shield, the motor-driver board, bluetooth module, 3x line sensor modules, IR receiver, ultrasonic transducer, and servo for example. There's lots of potential for re-using all this in other experiments. The software all comes on a CD, but there's a QR code on the CD that points to: (a google drive URL that desertcart won't let me post) where you can download the contents of the CD if you no longer own a computer with an optical drive. Review: Great Product to teach and learn - I bought this for my 9yo son so he can get a head start on learning robotics. It is too advanced for him by himself now, but It is a good kit for me to teach him. I would highly recommend this as a starter. This kit has everything you need to make the car and it has the sensor board that can be used in other projects. (I will be buying the sensor variety pack too). It does require some basic knowledge of electronics (it is not as easy as Legos, but not as hard as building a homemade circuit on a breadboard), Even the completely inexperienced can find on-line tutorials to learn how to solder and learn a little about how the sensors work and how they can be hooked up. The instructions likely seem hard to people who have no basic knowledge. ## Features - The tutorial include codes,labraries and lessons.It will teach every users how to assembly the smart robot car kit and use R3 controller board, sensors and modules.Note：Batteries are not included in the product. - LAFVIN robotic car learning kit is designed for beginners to learn Arduino programming and get hands-on experience on robot design and assembly - This kit includes R3 Board HC-SR04 Ultrasonic Sensor,V5.0 extension board,Line tracking module,etc. - You will learn the Line Tracking, Ultraviolet Obstacle Avoidance, IR Remote Control, Smart Car, you can also extend other functions on this robot platform. - This car really excellent and safe to be a perfect gift for your friend. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07JN46YSW | | Age Range Description | Kid | | Best Sellers Rank | #1,439 in Single Board Computers (Computers & Accessories) | | Brand Name | LAFVIN | | Customer Reviews | 4.0 4.0 out of 5 stars (167) | | Educational Objective | Obstacle Avoidance | | Included Components | CD | | Is Assembly Required | Yes | | Item Dimensions | 10 x 7.6 x 3.5 inches | | Item Weight | 2 Pounds | | Manufacturer | LAFVIN | | Manufacturer Part Number | LA-016 | | Manufacturer Warranty Description | 2 months | | Material Type | Plastic, Metal, Acrylic | | Model Number | 8541582531 | | Size | 10 inches | | Theme | Car,Robot | | UPC | 781520418727 | ## Images ![LAFVIN Smart Robot Car Kit Include Ultrasonic Sensor,R3 Board Compatible with Arduino IDE with Tutorial - Image 1](https://m.media-amazon.com/images/I/71i4El9e4QL.jpg) ## Questions & Answers **Q: Do you guys have a website where I can download all the stuff from the CD?** A: http://www.lafvintech.com/ But the website does not show any links for downloading the CD contents.

The instructions likely seem hard to people who have no basic knowledge. ### ⭐⭐ Not for beginners please read *by D***N on November 17, 2025* The instructions do not match the kit I received. Also my kit was missing a couple of sensors and some hardware. I found it easier to buy replacement parts to see if I could get the entire project done. Well, this is not for beginners. I am now in the process of going over the code to make far too many corrections. If you are experienced with code, which I am not; then this shouldn't be too much of an issue, as for me; This kit will be built in multiple stages as I build the code for each function. For beginners I would consider doing far more research than I did. Look through the reviews and go to the seller website and look for support before you purchase. ## Frequently Bought Together - LAFVIN Smart Robot Car Kit Include Ultrasonic Sensor,R3 Board Compatible with Arduino IDE with Tutorial - LAFVIN Project Super Starter Kit for R3 Mega2560 Mega328 Nano with Tutorial Compatible with Arduino IDE - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/95891295-lafvin-smart-robot-car-kit-include-ultrasonic-sensor-r3-board](https://www.desertcart.sk/products/95891295-lafvin-smart-robot-car-kit-include-ultrasonic-sensor-r3-board) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-22*
