This project was done by an adult to learn the basic ways boards, sensors and chips to build art works. Well made and has some weight to it. Great hands on project. Children will love the project and learn how to add to it. My next step will be adding cameras. I bought the project for the board and for $20 more I got a full kit.

I bought this kit for my grandson for Christmas. We just built it today. I have to say I am really, really impressed with the quality of the design and the components. Everything went together very easily, and the directions were top notch. It turned on and performed well! This is an excellent kit, with lots of possibilities. The technology available today never ceases to amaze me (I've built about two dozen Arduino projects from scratch over the last few years, but this kit is really good). I haven't even tried the remote control functions with a phone yet. Well done Elegoo!

Great project for the budding engineers

Works as advertised, very cool device. Assembly was easy, only requires beginner skills and the ability to follow instructions, if that. A screwdriver was even included. Could have used a small wrench for the pillars but any pliers will work. Only problem with my kit was the battery mounting plate did not have holes for the battery screws. Not a challenge for me to drill two holes and move on. If you have this problem just put some masking tape on the plate in the right area then draw the hole location on the tape with the battery in the right place. Drill hole and repeat. The apple app is not terribly intuitive but does work, I may go find my tablet and try that but I doubt it's much different. I have not modified any of the installed software yet but i will soon, maybe an update then. The Elegoo site has all the manuals and software available for download including 3D models of some of the parts. All the data sheets are there as well! Not paid for the review and have bought several of their products in the past. Edit:- I did contact the support email and they replied within a business day. An offer was made to send me a replacement motor mount plate, which i declined. Very good support team.

I've recently put together a couple different mobile robot kits and the Tumbller is easily the highest quality. The parts are clean and assembly is straightforward using nothing more than the included paper manual and screwdriver. In fact, it took longer to charge the battery than it did to assemble the Tumbller. When I finally turned it on, it stood upright as promised. Some of the screws and parts are quite small so manual dexterity is required and you should work carefully over a table or bench. Elegoo thoughtfully provides a small number of extras in case of loss during assembly. The one complaint I have is the difficulty of finding the software. The Elegoo website is largely devoted to their 3D printers with only the vaguest links to their robot cars. It required many start-over attempts plus some imaginative Google queries before I was finally able to track down what I *hope* is the github package, and I have no assurance that the sources thus obtained are what's actually running in the Arduino Nano. Getting the source code is important to me because I want to understand the self-balancing algorithm and I also hope to devise some sort of radio control other than the smartphone app provided. One possibility is replacing the Nano with a Raspberry Pi Pico W or some other microcontroller that is WiFi capable. This is certainly going to be $90 worth of fun! Update: I finally obtained the Arduino source code for the Tumbller but was unable to get it to work due to a certain section of code which caused the Nano to reset. As a last resort I sent an inquiry to Elegoo support. Rather to my surprise, I got a reply indicating the technical solution. Support like this speaks well of Elegoo as a vendor.

This kit is a good fit for kids who already like building and problem solving. Assembly and setup take some time, but the instructions are clear with a bit of adult help. Watching the robot balance itself is genuinely satisfying and introduces real robotics and coding concepts. Not a quick toy, but a worthwhile STEM project for the right age.

I was completely surprised at the build quality of this! My 6yr old son and I built this with no problems at all. We found the instructions easy to follow. The pictures were also helpful.

El artículo llegó completo y mi nieto lo está disfrutando mucho, juega con el constantemente y está encantnado con es te regalo

Es un buen kit, y bien desarrollado, es muy útil para estudiar programación y puede ser ampliado, para otros nuevos proyectos, saludos

Le gustó a mi hijo y lo reco7

Buen producto me sirve para mis proyectos

Vienen cables de los motores equivocados. Se consiguieron los conectores por separado y funcionó perfectamente.
