The perseids DIY Robot Smart Car Chassis Kit with Speed Encoder, Wheels and Battery Box (4 Wheels)

The parts were packed in a plastic bag, the base was broken.

Excellent. I've had this little thing running around, powered by a Raspberry Pi Pico for a while now.

I do not write reviews very often, but I have to say something about this item and the customer support I received. I bought this chassis for my raspberry project and it was a perfect match for my needs. Somehow, I lost one of the small pieces to attach the motors to the chassis. I contacted customer support via email. I received an email within hours. They sent me a picture of the item missing and asked me how many I needed. Long story short, they sent me two extra pieces for free in the mail, It took some time because It came from China but I am very happy with this kit. Thank you very much.

These are great kits to simplify construction of Arduino robot cars. Used to spend most of my time manufacturing a chassis from poster board and mounting motors with hot glue. Now most of my time is spent where it matters: developing robot cars with different operating modes, including obstacle avoidance, bluetooth via and app or joystick, and radio-controlled using nrfL24 transceivers. But yes, it is made of brittle acrylic, so you need to be careful, especially around younger children. On the plus side, you can pay around $15 for a set of four motors and wheels alone, or you can pay the same price for a set of four motors and wheels INCLUDING A CHASSIS. This is a no-brainer. Would give it 5 stars if not for the brittle acrylic. Deserves at least 4.5 stars, but not possible to award half a star. Highly recommended for those interested in spending time building cars instead of constructing chassis from whatever material is at hand.

Very flimsy frame and bad build quality. It's hard to mount the wheels. I ended up damaging one of the motors while trying to mount them. Also, the wheels rub sometimes rub against the frame after they are mounted. Would not recommend!!!

Overall good value for money - would have been perfect if wheels had been screw-on instead of snap-on. - spacious - was able to fit arduino, batteries and 2 h-bridges with room to spare - multi-level - so more space available on bottom deck if needed - hard to remove baseplate covering - used acetone as suggested by another reviewer - wheels do not fit tightly with the motor shaft, wobble and fall off easily - acrylic tags that hold the motors are brittle - broke 4 of them while trying to get the wheels to grip more firmly with the motor shaft Tried securing the wheels with loctite - still fall off e - if the wheels had
