Review: العجلات لا تعمل
Review: I'm in the process of assembling it currently. Issues and comments so far: 1) The plastic pieces are laser-cut out of acrylic and have a protective adhesive paper on both sides that you will want to peel off (unless you like the look of that over the clear plastic) 2) The manual calls for M3*8mm screws to attach the motor driver board to the baseplate, but the kit included M3*6mm screws (correct according to the label in the bag) which are too short to reach through the 1/4" acrylic baseplate. This required a trip to Home Depot to acquire some M3*10 screws (Hint: they store the metric screws in drawers way down the aisle from the rest of the machine screws) which work but are *almost* too long. You just need four of them as the 6mm screws work fine for mounting the Arduino on the thinner upper deck. 3) There is one acrylic piece with a right-angle bend used to mount the ultrasonic transducer. This is made by laser-cutting a flat part and then heating and bending the end, likely by hand. In my case, the bend is less than 90 degrees and will result in the transducer pointing down at the floor without some kind of shim or other adaptation. I ended up only installing the two bottom spacers and gently tightening the nuts which gave it just the right level of upward angle to compensate. 4) As all the other reviews correctly point out, the system is powered by two 18650 batteries but no way to charge them is provided and most people will need to acquire a separate charger (that will probably cost more than half what the entire kit costs). It should be clearly stated in the product description that everything you need is not in fact included. 5) The connection of the ultrasonic transducer assemby to the servo is not illustrated and is fiddly. You need to attach the servo arm that comes with the servo to the servo FIRST (it won't fit through the middle hole in the tranducer assembly tab) with the small screw incuded with the servo arms. Then they want you to use the servo mounting screws to attach the acrylic bent tab of the assembly to the servo arm, which requires you to use only the outer holes to avoid hitting the servo, and those screws are way to big for this and do not align well with the holes in the servo arm. 6) The assembly instructions really don't touch on wiring everything together, and have you mount the top deck before getting into the experiments where they talk about wiring the motor driver board which is between the two decks and not possible to wire with the top deck installed. 7) There are specific experiements and code for operating each of the sensors etc. separately, but most of these do not involve the car actually being driven. It's not yet clear if there will be enough storage to load all the required drivers to operate everything together. There's only one complete robot experiment provided which is a line following application. You're pretty much on your own to do anything cool like using the servo and ultrasonic transducer to scan the area in front and choose a path say. 8) While there are four motors, one for each wheel, the motor driver board only has two outputs in differential (+/- bidirectional) drive mode so the two left motors are wired together and the two right motors are wired together. I'll update as I make further progress. Otherwise, it's a great kit due to the large number of components you get. The UNO 3 compatible, the sensor shield, the motor-driver board, bluetooth module, 3x line sensor modules, IR receiver, ultrasonic transducer, and servo for example. There's lots of potential for re-using all this in other experiments. The software all comes on a CD, but there's a QR code on the CD that points to: (a google drive URL that desertcart won't let me post) where you can download the contents of the CD if you no longer own a computer with an optical drive.

Me gustó que viene muy completo, y lo malo es que algunas de sus piezas son muy pequeñas y las puedes perder... Y cuando lo estás usando y se llega a topar con un objeto se le afloja su sensor ultrasonico.
