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!!

This kit is really great. I purchased this for my 8 year old grandson. He was able to put together without supervision. The step by step instructions were great. You can use your phone or the included remote that came with the product. He played with it a few time but has it on display to preserve it i guess. But he does take it out from time to time and play with it. Money well spent.

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!

Built this with my grand kids. Fun to build. Not really that good at function. Never could adjust it to go in a straight line.

Assembly was straight forward. Software use {programming) is much more complicated. Some extra small parts were provided. Screwdrivers were provided but no wrenches or nut drivers. Must be able to handle 1.6 mm nuts and bolts. That's the trickiest party of assembly.

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!

Great beginner kit with clear instructions. I thought parts were high quality for the price point. Would be even better if the instructions gave information about the components as you are installing them to educate the student as they build the car. IE: the line following component works by ... ... One area for improvement is the controls aren't perfect and the device is a bit challenging to control as a remote control, but since our goal was to understand the electeonic components this is five stars for us.

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.
