hours to assemble the "Humanoid" robot and get it to make its first move. Ubtech obviously spent a lot of time on the 3D step by step assembly instructions. They were flawless and we had no issues understanding the build. After we finished, the app has several pre-programmed moves that make the robot "Dance", or move side to side, etc. But that is where my initial enthusiasm wore off. There is no substantive instructions on how to program the robot to do other things or to use the "Blockly" snap together programming language. No youtube videos, nothing on the UBTECH website and no "Community" to ask questions. So I have been trying to figure this out on my own for the last several weeks but it really is like trying to learn a foreign language. Several times I have entered an incorrect code or pressed an incorrect button and the robot will flop to the tabletop or go "Limp" and drop hard onto the ground. So overall it is worth the money and I am glad I purchased it. I haven't given up on learning to program it, however, without programming instructions or help, it is little more than an expensive radio controlled car.

ed quickly and worked flawlessly once I received it. Their customer support staff was also pretty quick to check to ensure I received the replacement part in a timely manner and ensure everything was working correctly. So, it appears that post-holiday UBTech Support is quick to address customer issues and provide replacements/support for defective items.

I still wish the robot came in a more user-friendly box, but I cannot complain about the instruction/programming app, as it allows the user to see the robot/model from multiple angles while assembling. Selecting programs and running them once the robot is built is a cinch. Now that robots/models built with the JIMU Inventor kit actually works, I am quite happy with the product and will introduce it to my class to demonstrate fully articulated robotic models. Hopefully UBTech/JIMU provides some type of IDE to program creations using a programming language beyond drag and drop blocks, but we will see where things go. There is a lot of potential with this robotics kit!

NOTE: This product has great potential, but as others have reported the battery is a VERY common problem. If your battery flashes green/red while "charging, and does not eventually display a solid green light, you probably have a defective unit and should troubleshoot it through UBTech's website.

This would be an excellent robotics kit for what is in it, but there are some flaws. If the battery does not work, you're basically left with a 2/3-scale LEGO EV3 kit and 16 servos for floppy joints (no power, no rigidity), so user-replaceable parts are a must.

Other areas needing improvement:
- Everything is packaged in a nice box, yet all of the multitude of tiny pieces are in baggies within cardboard boxes. While it looks really nice, the cardboard will not fair well with repeated use and the baggies make it difficult to hunt items needed in the builds. Dumping the pieces into the small cardboard boxes is not any better, as there are holes at the top/bottom of the boxes for removing from the compartments in the "book." This kit should have come in a more durable plastic box with easily accessible compartments or at least replace the cardboard boxes with more durable plastic or vinyl boxes.
- The LEGO-like pieces are not consistent in shape/fill. The beams are not smooth all around, but have small hollow areas and many have small holes at one end (perhaps from the manufacture process).
- The manual is only available on a Tablet or phone, no physical copy is available. While I was quite upset with this at first, I found during the build process that it was nice to be able to rotate the model around to see where things line up and fit together, yet a physical build guide is essential for many reasons: 1) if support for the product ends, the app may/will eventually stop working too; i.e., no more build guides, 2) not ideal for a classroom environment as no PC component, and 3) some people like to review all steps in advance by flipping through the build guide, using an app limits this option.
- No current IDE for programming the robot from your PC, though pre-programmed routines are available through the app for each model. Not being able to write and design programs for the robot limits its overall functionality. While there may be a "rag-doll" mode to program, this leaves much to be desired in the form of learning to program robots.
- I did have issues running the app the first few times, as it would crash, but this stopped after the first three (3) times. I am running the app on a 9.7" Samsung Galaxy Tab S2 with the latest updates, so platform should not be the issue. NOTE: I have had no other issues using the Android app since the initial errors mentioned earlier. The app runs smoothly, connecting quickly to the robot and build screens. It will also remember where you left off for when you are unable to complete a build in a single setting (good luck with that!).

*** After finally receiving customer support and a replacement part, I would recommend this robot for anyone wanting to build some great robotic models. The potential use cases is limited to walking robots, but is pretty interesting using the 16 servos for a wide range of movements. There are no wheels or sensors included in the robot, so it does fall if it moves too quickly and there is no way for it to detect anything outside of what it running inside the controller. Maybe an expansion kit will come out that adds sensors or wheels... :)

我不确定这是否只是节假日期间UBTech积压的客户支持，但他们确实联系了我并给我提供了一个更换电池。我在几天内就收到了新发来的电池，电池充电速度很快而且一收到就能完美的工作。他们的客户支持人员也进行了非常迅速地检查以确保我及时收到了替换的零件并且一切都是正常工作的。所以，这表明假期后的UBTech售后支持服务可以迅速地解决客户的问题，并未有缺陷的产品提供替换/支持服务。

我还是希望机器人能装在一个对用户更加友好的盒子里，但我不能抱怨指令/编程应用，因为它允许用户在装配时从多个角度看到机器人/模型。一旦在机器人建成后选择程序并运行它们是件轻而易举的事。现在，用JIMU发明家工具包制作的机器人/模型确实工作了，我对这个产品非常满意，并将它介绍给我的班级来演示完全铰接的机器人模型。希望UBTech/JIMU能够提供某种IDE来使用除拖放块之外的编程语言来编写程序，我们将拭目以待。这个机器人工具包有很大的潜力!

注意：这种产品有巨大的潜力，但正如其他人评价的那样电池问题是一个很普遍的问题。如果你的电池在充电时闪烁绿色/红色，并且最终没有显示出纯绿灯，你可能有一个有缺陷的单元，应该通过UBTech的网站进行故障排除。

这将是一个很好的机器人工具箱，但仍有一些缺陷。如果电池不工作，你基本上只剩下2/3的乐高EV3组件和16个用于软盘连接的伺服器(没有电源，没有刚性)，所以用户必须更换部件。 

其他需要改进的地方: 

-所有的东西都装在一个漂亮的盒子里，所有的小零件都装在纸板箱里的塑料袋里。虽然它看起来很漂亮，但是重复使用纸箱不是很方便，然后用袋子使得在组装中寻找需要的物品变得困难。把碎片倒进小纸板箱也没有什么好处，因为盒子的顶部/底部都有孔，可以从“书”里的小隔间里取出来。这个套件应该是放在一个更耐用的塑料盒子里，容易接近的隔间，或者至少用更耐用的塑料或乙烯基盒来替换硬纸板盒。

-类似乐高积木的积木在形状/填充上不一致。梁的周围不是光滑的，但是有小的空心区域，还有许多一端有小洞(可能来自制造过程)。

-手册只能在平板电脑或手机上使用，没有实体版本。虽然在刚开始很沮丧,但我发现在构建过程中能够旋转模型看到产品组合在一起还是很开心的，当然实体上的指导是至关重要的，原因有很多：1）如果支持的产品停止运行了，这个应用程序可能最终会停止工作；2)不适合教室环境，因为没有PC组件;3)有些人喜欢浏览构建指南，提前检查所有步骤，使用应用程序限制了这种选择。

-目前你的PC还没有IDE编程机器人，虽然通过应用程序为每个模型预先编程是可行的。不能被机器人编写和设计程序限制了它的整体功能。虽然编程可能会有一种“布娃娃”模式，但在学习编程机器人方面，还有很多需要改进的地方。

-我在前几次运行时确实会有问题，因为它会崩溃，但这在前三次之后就没问题了。我用9.7英寸的三星Galaxy Tab S2运行这款应用，并进行了最新的升级，所以平台不应该是问题所在。注意:自从前面提到的初始错误之后，我在使用Android应用程序时没有遇到其他问题。该应用程序运行平稳，与机器人快速连接并构建屏幕。它还会记住你在哪里无法在单个设置中完成一个构建(祝你好运!)

***在最终得到售后服务和一个替换部件后，我将向任何想要建立一些伟大的机器人模型的人推荐这个机器人。潜在的使用情况仅限于可以行走的机器人，但是使用16个伺服器让机器人做出许多动作是非常有趣的。机器人没有轮子或传感器，所以如果动作太快，机器人就会掉下来，而且除了在控制器内运行的东西外，它也无法检测到任何东西。也许会有一套增加传感器或轮子的工具包问世……

ction so you can switch different angles to assemble the robots. It comes with several official movements and you can also create your own movement. Now, the most fun part is the coding section that allows you to use logistical statement to code with blocks. We currently built the Human and Elephant, they are super flexible (can do back flip and hand stand etc.). Will build the rest of the models with children soon and then let them to try something by their own imagination.
I see a lot of reviews complain about the battery issue but none of mine has such cases (tips: charge the grey brain box before you start to build so you can play with them once you finish building). I think UBTECH has fixed this and really want to see more great products from UBTECH. It will also be great if they can provide future sensor add-on package since I saw lots of sensor function in the coding part.
Overall, I am very satisfied with this great product and highly recommend this to who wants to buy a coding/educational robot for their lovely kids.

我为学校买了20个发明家工具包，所有的孩子都很喜欢。在这个价格内拥有16个伺服系统是令人惊喜的。这些机器人配有一个漂亮的盒子(未安装)，所以你需要使用它的Jimu应用程序来构建和使用它们。该应用程序非常容易使用，对用户超级友好，特别是三维建筑指令，所以你可以切换不同角度组装机器人。它有几个官方动作，你也可以(通过编程)创建你自己的动作。现在，最有趣的部分是编码部分，它允许你使用逻辑语句对块进行编码。我们目前制造的人和象都是超级灵活的(可以做后空翻和用手倒立等)。(我)很快会和孩子们一起建立剩余的模型，然后让他们通过自己的想象力去尝试做一些东西。

我看到很多评论都在抱怨电池的问题，但我的评论中没有一个有这样的情况(提示:在开始构建之前，给这个灰色的脑盒子充一次电，这样在构建完成之后你就可以玩它了)。我认为UBTECH已经解决了这个问题，并且非常希望看到更多优秀的UBTECH产品出现。因为我在编码部分看到了很多传感器功能，如果他们能在未来提供传感器附加包，那就再好不过了。

总的来说，我对这个很棒的产品非常满意，并且强烈推荐给那些想为他们可爱的孩子买一个编码/教育机器人的人。 

le to discharge. Both kits batteries are showing near 0 volts and will not take a charge. This is unfortunate as the kit looks to be very well put together and interesting to use for my 10 year old.

我对这个工具包很失望。因为电池不能充电的问题我已经购买和更换两次了。使用的电池类型(LIPO)不能完全放电，这看起来有一个设计上的缺陷使得安装在控制模块上的电池不能放电。两组电池的电压都接近于0伏所以不能充电。对我10岁的(孩子)来说这是不幸的，因为工具包看起来是一个非常好的组合和有趣的使用 。
