LK COKOINO4WD Mecanum Wheel Smart Car Robot Chassis for Arduino R3 R4/ Leonardo/Raspberry Pi 5/4B/3B+/3B/2B/1B+ Projects with TT Motor, DIY Robot Building Base Kit for Teens & Adults

The acrylic parts are sturdy. The motor leads are long which is good. There are extra screws and nuts included in case you lose one during assembly. You have to provide your own electronics and batteries but that was clear from the product description.Overall I’m very pleased. This is the second kit I have purchased from this seller - the first was their robot arm and I would recommend them highly.

This kit is an excellent jumping off point for my project to build a remote controlled omni-directional car. The kit provides the chassis and all the running gear but no electronics or batteries (two 18650-style 3.7V Lithium cells). As well as those batteries the chassis supports installation of an Arduino UNO R3 or a Raspberry Pi 4b control board (with appropriate hats to drive the motors). However I intend to build my own ESP32 based controller with off the shelf motor drivers (MX1508 based, available on Amazon). This will be much smaller and tidier and I believe the chassis will adapt easily to my needs.The kit uses common off the shelf parts like the "yellow" gearbox motors and Mecanum wheels you see from multiple vendors on Amazon. This is good because it saves you from searching out the parts yourself but also because replacing parts that wear out should be easy. You assemble everything onto a black laser-cut acrylic chassis and the kit comes with all the basic hardware you need. On the lid of the box is a link to Github where you can download the "CKK0015 Tutorial files" which include assembly instructions and even some Arduino code to get you started.I followed the instructions in Section 3 of the tutorial: "How to Assemble the 4WD Car Chassis" and found them to be very well presented and easy to follow. If you have not used Mecanum wheels before, they come in LEFT-RIGHT pairs (two such pairs are in this kit). Follow the instructions (and copious diagrams in the PDF) carefully when mounting them to the chassis as a mistake will prevent the vehicle from steering properly. You can disassemble and remount easily but we all love to get things right first time. Simple tools like a wrench and screwdriver are included in the kit but the screwdriver is 100% useless junk, so be sure to have a good philips head driver available.Kit content is very well organized, all small parts are in labeled baggies and I was very impressed that the kit provides one spare of every screw/nut/bolt and even some key plastic parts like the axle adapters. My assembly took a leisurely 50 minutes and yielded a sturdy vehicle for me to build on. All 4 motors are working smoothly and I am waiting for delivery of the motor drivers to resume construction. There are a dozen or more projects on YouTube to inspire you but I have a favorite. I strongly recommend the excellent design by Dronebot Workshop on Youtube (search for "Mecanum Wheel Robot Car & ESP-NOW Remote") which is based on a similar kit to this. I plan to update this review with details of my build. Wish me luck.To sum up, I think this is an excellent kit for a very fair price. Packaging was a single cardboard box with all parts but no printed instructions. Just follow the github link on the outside (and inside) of the box to download the PDF.

The LK COKOINO 4WD Mecanum Wheel Smart Car Robot Chassis is an excellent starting point for anyone looking to build their own remote controlled vehicle. The chassis is well-made and sturdy, and the Mecanum wheels allow for omnidirectional movement, making it highly maneuverable.It's important to note that this is a kit and requires additional components to complete the project. You will need a controller, 18650 batteries, and a relay. However, the instructions are well-written and easy to follow, even for beginners.The materials used in the chassis are of high quality. The kit also includes all the necessary screws and tools for assembly.Overall, the LK COKOINO Mecanum Wheel Robot Chassis is a great choice for anyone looking to build a custom robot. It's well-made, versatile, and easy to assemble. Just be sure to factor in the cost of the additional components you'll need to complete the project.
