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! Read more

Really easy to build and a fun educational toy for kids Read more

Facil de armar y muy buena calidad de materiales y herramientas Read more

Robot kit is good for kids or for those getting into STEM. However, the documentation for the modified esp32-Wrover is not useful as it doesn't tell you how to reprogram the esp. Been struggling for a while to fix the issue but ots missing files and libraries. Especially the "Who" library as the documentation integrates a discontinued library that doesn't work with the new esp module. This is tough and frustrating when you're actually trying to reprogram or repurpose the existing components. Also, the model for the camera given in the despription is wrong. It uses an older jpeg camera. I cant confirm the exact model it uses as it's not a standard part but a clone. The range on the wifi module is really bad. Especially for homes with concrete walls. So it's a 3 star product for me. Read more

Very good Read more

Fast delivery. Easy assembly. Pre-Programmed. Functioning perfectly. Doesn’t require wifi connection. It creates its own wifi. Easy mobile application. Read more

Very nice , works with IOS mobile app , Camera and remote control all are excellent Read more

I recently purchased the Elegoo Smart Car V4 with Camera from amazon website as a gift for my son.L as it's a wonderful educational tool and a great introduction to robotics. Unfortunately, our experience has been disappointing due to a faulty Ultrasonic Sensor. Despite following the assembly instructions and troubleshooting steps carefully, the sensor does not function at all. This has halted our progress and taken away from what was supposed to be a fun and inspiring learning experience for my son. I am kindly requesting a replacement for the defective Ultrasonic Sensor so we can get the Smart Car fully operational. I hope this issue can be resolved quickly. Thank you for your attention, and I look forward to your support. Read more

it s very good item to our child who are interest to assemble the products. it is helpful to improve our kids knowledge. wonderful item. Read more

Received as described. Excellent product, items quality is excellent, I have assembled it with my 12 years old son. He enjoyed a lot. It worked perfectly after Assembly. This product is worth for money. Highly recommended. Read more

totally recommended. I had a lot of quality time with my 6 years old son , assembling the robot. It's way better than any remote controlled tank, let alone the ability to teach your kids robotics and programming Read more

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. Read more

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! Read more
