UNO R3 Smart Robot Car Kit V4 with Camera, Compatible with Arduino

We had a fantastic experience building the ELEGOO robot car kit. The directions were clear, straightforward, and very easy to follow — at no point did we get stuck or confused during assembly. There are many small components included, and while some pieces come with spares and others do not, everything was well organized and fit together smoothly. The build process was actually part of the fun and made it a great hands-on learning experience. Once assembled, the robot performs really well. The controls are responsive whether using the remote or the mobile app, and both options work reliably. Watching it drive around and avoid obstacles is incredibly satisfying! Overall, this is a fun, well-designed kit that’s perfect for beginners and a great educational project for kids and adults alike. Highly recommended!

This Smart Robot was my introduction to Elegoo products and the experience has made me a diehard fan of Elegoo. I bought this for my 9 year old son as a gift for the holidays. This was my attempt to give him gifts would peak his interest enough to get him away from all the games and electric devices and this did the trick. At first when I first opened it I wondered if it was to much for him to assemble but boy was I worng. He enjoyed every moment of it and has not stopped using it. Its so much fun that everyone in the house is enjoying it. It was designed and packaged so well and the instuctions were very easy to follow. Love the care they took and the packaging was neat and well organized. In its default state its packed with features but the intro to Arduino IDE increases its value immensely making it possible to add more components, features and functionality. This has already paid for itself times over and its value for money is undeniable!!

I've assembled several robot kits like these but this has got to be the best so far hands-down. Everything about this project is well done from the packaging (components are well labeled in separate boxes & baggies) to the documentation (printed and download). I was able to follow the included printed assembly manual and put the robot together in about an hour. Elegoo has even included three small tools so you won't need to use any of your own unless that's your preference. The included Uno clone is preprogrammed with all of the necessary functionality so all you've got to do is power it on and choose the desired function via the IR remote. You can also download an iOS or Android companion app to control the robot via bluetooth although that's not something I've tried yet so I can't comment on how well it works. Of course, the Arduino software is available from Elegoo's website if you want to experiment with uploading your own sketches. I downloaded the surprisingly large zip file for this product (1 GB) and briefly browsed the multilingual contents. They've done a good job with this documentation as well! The Arduino source code is included by various build/functionality stages and PDFs are included that explain everything in that particular stage. This little car really zips along, too! I haven't tested the line-following function but the obstacle avoidance function works pretty well. It can get stuck in this mode if the car approaches an object at a shallow enough angle which doesn't trigger the ultrasonic distance sensor but waving your hand (or foot) in front of it does the job. Manual drive mode works very well using the included IR remote. TL;DR: Quality of the electronics is fair, hardware is excellent & solid, documentation is really excellent for non-native English speakers. It is actually a bargain for all of the components you get and how well the fit & finish is. My only gripe is how easily fingerprints and dust show up on the piano black acrylic body pieces. That's a minor annoyance, IMHO. If you're on the fence about buying this, you shouldn't be. It's honestly a great robotics project that gives you more than you'd expect for the price. I'll update this review if I encounter any problems but, so far, it's worked well!

My granddaughter and I built this car yesterday. Aside from some gymnastics required to hold parts together while fastening with microscopic nuts (for which they thoughtfully provided spare pieces), it went together well, and quickly! I loved how each ziploc bag of parts was labeled, and the labels were referenced at each step (Hint: if you empty a bag to sort parts, put the unused parts back in the bag to make it easier to find them for use in a later step), and the illustrations included actual size pictures of the fasteners to help alleviate any confusion. Best instructions I’ve ever had with such purchases from Chinese companies! My granddaughter enjoyed putting it together, and was thrilled with it when we turned it on and let it go. We’ll experiment with changing the program to make the car do different things, and, maybe, adding some additional servos... My one complaint is that the power switch on the battery pack does not work - as soon as we plugged it in, the board was powered and changing the switch position did nothing, so we control power by unplugging the battery box from the board. Had this not been the case, this would have been a 5-star review. There were also some servo horns in the package with no mention in the manual, and no apparent application on the car. We’ll hold onto them for potential future additions to the car, but they did cause some confusion as my 12 yo granddaughter pored over the documentation looking for them.

SUPER fun kit. Quite easy to assemble if you're are an experienced model builder. If you're new, just make sure to lay out the parts needed for each step, and take your time. IMHO, they need to have a "parts kit" page that shows what pieces/sizes are in each bag, to make it easier to find for each step. The small parts bags are labelled for each section, but I found that you need to cross-over to other bags in some steps. Lots of devices for a "beginner" kit. It includes 4 separately controlled motors for the wheels, a camera, ultrasonic sensor, line-following sensor. There is a servo on the camera/sonic "face" so you can turn it. A few extra parts are included for further experimentation. Works great after assembly, using just the remote. It's pre-loaded with the code that it needs, so there is no programming necessary for it's basic uses. The IOS app is easy to connect and use. Looking forward to programming this beast.

First there are a handful of incredibly tiny screws (mostly for the servo and ultrasonic head) get yourself a magnetic parts dish and work over something like a white table cloth (if you drop them you'll probably never see it again). Assembly took maybe an hour & the directions are pretty thorough. The parts bags are individually labeled so its virtually impossible to use the wrong hardware. Everything is backed up with videos and online tutorials but we didn't need any of that. given the sizes of the parts, I started the hardware (to avoid losing parts) and let my son tighten everything up so he could get in on the build. All the tools you need are included but feel free to use a little locktite or a better quality screwdriver to firm it all up. It comes pre-programmed to follow lines, run by IR like a remote control car and do basic object detection. the object detection can be upgraded later so the head continuously searches rather than waiting until it meets an obstacle. its also programmable & controllable via pc or phone app. Since its an Arduino Uno you could probably add more sensors...but we'll leave that for another day. While it doesn't meet my 7 year old's desire to have a 30' tall robot, its a good intro into the processes of programming, building and robotics.

Great educational Robot, good value for what you get. Our grandkids are having so much fun using the robot. The 12 year old is navigating it around the house from his room. He uses the built in camera to navigate and avoid walls/objects. The android app works great, video quality is actually very good and clear (HD). However, building it requires much patience to follow the instructions, there are lots of screws, many extremely small, therefore, this may require adult assistance and guidance.

An impressive work combining different solutions to real-world problems! The Smart Car has features like: Ultrasonic Range finder for collision avoidance and semi-autonomous navigation; Optical sensors for line following navigation; Bluetooth connection for remote control operation; and an Infrared Remote Control. All these modes of operations work flawlessly except the IR sensor. In my opinion, this is not Elegoo’s fault. However, the engineers at Elegoo could have evaluated the performance of the IR sensor and could have removed it from the kit as the Bluetooth function is enough for manual control. IR remote control operates in the infrared range just below the red end of the visible spectrum. It works in a line-of-sight that will easily be obstructed by nearby objects. It also suffers from interference from other IR devices in the vicinity. For these reasons, IR is not a good device for non-stationary devices. Likewise, the built-in IR works intermittently while the Smart Car is in motion. Elegoo has also provided a smartphone app for both Android and IOS platforms. You can also create your own “DIY Control” remote app, which I like it so much that you have the freedom to program the remote control that suits your need. Overall, I gave this Smart Car a five-star rating. It is a great kit for DIY projects and also for Smart Car base code development exercises. All you need is to assemble the kit, download the Arduino sketches from the Elegoo's website, and use the Elegoo App to control the Smart Car. Most importantly. Have fun with modifying the codes and eventually develop your own code. So far, I have modified the carSpeed and ultrasonic range to suit my interest. I have also added RGB status indicator light, and I have also added a second infrared sensor. Most of the Arduino GPIO pins are occupied but there are few open pins like A0, A1, A2, and A3. So, I have used A0-A2 for the RGB LED light and pin A3 for the second IR sensor. FYI, the built-in IR sensor is connected to PIN 12 so you can change it to A3 on the Arduino sketch and connect a new IR sensor to PIN A3. I am also working on adding a piezo speaker; however, the Smart Car is using both the timers of Arduino UNO and I need Timer2– for functions like tone(), notone(). So, I might probably change the Arduino UNO with Arduino MEGA and add more features to the Smart Car. In conclusion, the Elegoo Smart Car is an excellent engineering toy for all levels. Have fun and try to modify the codes and the hardware to match your own needs. FIVE STARS!

Good for kids

The base/top plates are sturdy, even though they are plastic. Instructions are clear enough to understand and assemble. The UNO comes pre-programmed. So once you assemble it, you can start using it like a toy. App control is seamless. All default functions work well. I haven't figured out yet how to customize the programming, for example, do various other computer vision tasks.

Good quality.

A mi hijo de 12 años le encanto, facil de armar, instrucciones adecuadas.. Solo una queja hay una parte donde se aflojan los tornillos

Muy contenta con la compra, llegó en excelente estado, gracias.
