ELEGOO UNO Project Smart Robot Car Kit V4

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 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.

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.

The kit is fine and my 11 year old had no trouble putting it together. I'm glad it doesn't require a phone app to function, except for the camera. The big problem is that although it's powered by an Arduino, there is NO programming required. The code that runs this can't even be downloaded from the Arduino board into the IDE. I was looking for a programming + building project, not a building project that already had all the hard work of coding handled by someone else.

My son loves this robot car kit. Very hands on and a good challenge. Good quality.

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!

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.

This was a great project to do with my grandson. It allowed him to be part of something fun and to challenge his ability to follow instructions. The end product was an awesome remote control car and a better understanding of electronics.

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.

Es maravilloso! Totalmente apto para niñas y niños inquietos y curiosos!

Very nice

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.
