all ok

Não e bom mas fiquei com sensação de não estar completo enfim

Extreemley fun. The RPi pico can be used for tons of other stuff.

Freenova社のキットは，６脚のくもがたロボットに続いて２種類目になります。ラズパイ(Pico_W)のインストールで躓いて，サポートにメールをしたらその日のうちに動画付きの返信が届きました。以前にも問い合わせへのレスポンスが早く的確だったkとを思い出しました。商品の方はこれからいろいろと試してみることになりますが，今のところ順調です。なお，PCからPicoへのデータのダウンロードの際には付属のUSBケーブルを使いましょう。私はこれで！はまりました。ご存んじの方が大半でしょうが，そこらのケーブルだと充電・給電しかできずデータの送受信ができないものがあります。ご注意ください。なお，画像のキットは，メカナムホイールを金と都は別のものに変えてあります。

This is a review of the Freenove Mecanum Wheel Car Kit for Raspberry Pi Pico W. I don't usually leave reviews on Amazon, but I was sufficiently impressed by this kit that I wanted to share my experience with others who might be considering it.The kit is built around the powerful Raspberry Pi Pico W microcontroller. It connects a variety of components to the Pico, resulting in a smart car that has a range of capabilities and that offers many opportunities for learning and extension. Among the components are:* four mecanum wheels with motors. These give amazing mobility to the car: it can spin around its own axis; circle around an external point that it is facing; move directly left, right and diagonally; as well as go forward and backward, make turns, speed up and slow down, and the like.* light-sensitive photoresistors. These allow the car to measure the brightness level on its left and right sides so that, for example, you can have the car chase the moving light from a flashlight.* optical sensors underneath the car. With these the car can, for example, follow a track that you have laid out on the floor.* an ultrasonic distance measurer mounted on a servomotor that swivels to the left and right. With this you can, for example, have the car change direction when it detects that it is getting close to an obstacle.* an infrared detector that receives signals from a handheld controller. This lets you command any function on the car from a distance by pushing buttons on the controller.* a wifi receiver on the Pico W that again lets you command any of the car's functions via an app from another wifi device such as a smart phone.* other fun things like a LED array that can flash simple pictures; a set of NeoPixel LEDs that can be programmed to change colors according to a pattern; and a buzzer.These are all included with the very reasonably-priced kit. (The only things not included are a pair of high drain 18650 rechargeable batteries and a charger, which can be found on Amazon and elsewhere.) The car's tutorial explains clearly how to mount and connect the components. This is not a difficult kit to assemble, although some of the attachment nuts and bolts are small and want a bit of care and dexterity in handling. The completed car seems solid and robust, and not likely to be damaged by reasonable use.The kit is accompanied by a downloadable software library that provides programmatic access to the car's various components and their functions. The library includes examples (in the form of simple program "sketches" that can be uploaded to the car) that show how to use each of the components. In many cases the examples cover both a basic component use (e.g. how to measure distances with the ultrasonic module) and a more complex one (e.g. how to use the distance measurements to automatically steer the car away from potential collisions). The tutorial discusses each of the examples in detail, so that the reader comes away with an understanding both of the low-level outputs of the car's components and of higher-level program logic to transform these outputs into useful actions. (While the tutorial does not teach programming, anyone with a basic knowledge of C/C++ should be able to follow along.) With this knowledge, a builder is prepared to go beyond the provided examples and develop new applications for the car.I also wanted to mention the very high quality of the customer support that Freenove offers. I contacted them with some questions that I had about the kit while I was building it, and they replied promptly and with information that was very much to the point. We had several email exchanges, and throughout they remained patient and committed to helping me resolve the questions that I had.In my opinion, this is an outstanding product for those who want to learn about developing mobile hardware/software systems like robots and smart cars, and I have no hesitation to recommend it highly.

Der Bausatz von Freenove enthält alle elektronischen und mechanischen Komponenten für den Aufbau. Die Software und Dokumentation stehen als Download zur Verfügung. Ich habe schon vor dem Kauf die Anleitung heruntergeladen und daraufhin den Bausatz gekauft. Zunächst wird der grundsätzliche Umgang mit der Arduino-IDE und deren Anpassung an den Raspberry PICO W erklärt. Beim Zusammenbau werden dann die einzelnen Komponenten auch bereits mittels einfacher Programme getestet. Erst zum Schluss wird der gesamte Funktionsumfang zusammengeführt. Für das Verständnis und um Interesse an eigenen Programmen oder mindestens programmtechnischen Veränderungen zu entwickeln ist das ein gut geeignetes Konzept.Die verwendeten Getriebemotoren für den Antrieb haben mich nicht sehr überzeugt. Sie werden in derartigen Systemen häufig eingesetzt. Die Achsen sind sehr labil. Alle Räder eiern mehr oder weniger.Weiterhin enthält die Android-APP zur Steuerung des Fahrzeugs einen Fehler. Die sogenannte Emotion-Matrix (Darstellung von Augen) wird nicht angesteuert. Ich habe zunächst in der Software für den PICO nach dem Fehler gesucht. Die ist aber i.O., denn wenn die Steuerung vom Windows-PC aus erfolgt, dann funktioniert auch die LED-Matrix.Einen Stern ziehe ich also wegen des minderwertigen Antriebs und der fehlerhaften Android-APP ab.

Można by jedynie wymagać lepszego dopasowania elementów montażowych do silników oraz innego oprogramowania do Sonaru. Zastosowane bez przerwy kręci serwem na wszystkie strony, to irytujące!
