DIY 4WD Smart Robot Chassis Kit, Robot Smart Car with Speed Encoder Battery Box 4 Wheels Robotics Kit for Adults (4WD Robot Car)

I bought the 2 WD for a small Bluetooth car using arduino uno r3. The instructions weren’t the best but they included pictures.putting it together was simple and self explanatory it was a fun project. (Please don’t judge my wiring I didn’t have any male to female jumper cables)

Great little kit to get my arduino mobile. Instructions are a little hard to understand only because of the bad translation, but the diagrams are good. I'm very impressed with this for the price. Haven't fully assembled it yet but all motors have been tested and work great. I would recommend this to anyone trying to make an RC car or autonomous Arduino vehicle. Great buy for the price.

One of the motor casings was missing a gear, but other than that it is a great kit.

Personally I had no issues with any of the parts breaking on me. The two acrylic frames do bend, so I would be gentle with it when it comes to putting anything heavy on it. The motors are slow, but for 15 dollars it’s not too bad. (Also, if you plan on hooking all four motors up to an Arduino I would make sure you have enough power.) One little annoyance for me are the little copper leads for the motors. They seem very flimsy but just try not to break them and you’ll be okay. Lastly, the directions that came with the car are pretty bad and not clear at all, but luckily it’s pretty straightforward when it comes to assembling the thing. Would recommend if you want to get an inexpensive car to toy around with.

In theory this little fella is the most bang for your buck. Chasis, 2 motors with encoders, battery box, and beefy wheels look great online but in person lacks punch I expected. Adding to that, the chasis was partially cracked (super glued), one of the motor mounts snapped when installing (super glue, again), instructions were translated horribly, came with way too many extra screws which made using quantities to make heads or tails of which screw and nut went where, and a holes not lining up here and there makes me regret this purchase. Would send back if shipping wouldn't cost half the purchase price.

Great product and great service from the seller!!! It was simple to assemble and it works as expected. Even though there missing parts the seller provided a good solution and in a timely manner.

I used this to make a robot car for my niece. Great kit! Note that in the video I have the motor speed varying according to distance ahead, it's been limited to between 50% and 65%, movement is autonomous, and I used another acrylic plate from a second kit as a topper. I had no problems at 100%, but this was for a child.

this is pretty great. i broke a couple of the motor holder brackets during assembly. most likely my fault. its a pretty fun robot once you get the motor board and the computer board.

The kit works well as my raspberry pi robotics platform, motors need to be driven at > 7 volts for it to skid turn properly. The rubber strap on each engine/gearbox were defective upon receipt torn from the housing ..with that said they still work for the time being.

Excelente

Nothing to dislike. I used product for Arduino project.

After connecting everything together properly without issue, with the batteries inside the device but turned off, the positive wire of the battery pack began to heat up. Eventually, the batteries started to smoke and even explode. The only reason it didn’t cause more damage was that I heard the noise coming from the batteries and saw them expanding just from making the connection, even with the device off. This didn’t happen immediately—it took about 5-8 minutes for everything to unfold. If left in the hands of a child, as the packaging states is suitable for ages 8 and up, this could be dangerous. I’d say this is a serious defect that might be present in more of these products. Fair warning to both sellers and buyers—please take precautions to avoid this situation. I believe it’s not an issue with all products, just some, but mine unfortunately was one of them. Since then, I haven’t purchased from this company again unless they show progress in preventing this from potentially destroying someone’s home or harming someone.

The base panel delivered with a lot of scratches and broken. Cannot be used
