Otto DIY Reviews 

I bought the humanoid ninja and I am very satisfied, the explanations are very clear and the construction is very playful as well as the programming. There are many possibilities to code and play with the buzzer, sensors and other features... The Otto diy team is also very helpful and reactive. They sent me back parts that were defective and answered my questions very nicely.

So far so good! Support and logisting tend to work perfectly even the initial order was delayed.
We all learn from mistakes but it seems that OttO team is "striving for excellence"

Great supplier, Customer service is very good, a best open source project, a best learning kit for teaching and learning, i get a lot of support from vendors and the community,

Everything to me is great with OTTO DIY

I was the lucky winner of an Ottoky and have been enjoying working with the product. It is a great experience to build the robot from scratch and learning to programme it. The blocky option is a good place to start if you are new to coding and you can easily see how the blocks convert to code. There are several online workshop videos to follow to progress with your learning and the community is very active so it's easy to get help when stuck. Overall, Otto is a great way to learn while having fun... and not just for kids!

Missing instruction. The engines didn't fit in the bearings (legs), so you have to 3D print new ones yourself.
Engine - Electro motor does not fiting on plastic legs.

Otto is such a great product to have a good time building something by yourself (great activity to do it with kids too) and bringing it to live! Easy follow instructions and different ways to programming it by yourself or use the commands already predefined. The app (available for Android & iOS) is also amazing.

The robot is even better to teach tech! As a EdTech teacher, Otto is a very good option to engage students into Computer Science activities. Very recommended!

It's an Open Network of Robot builders spreading a STEAM Robot that improves Technology in Education.

I have ordered two robots, Otto humanoid and Otto wheels, on Otto wheels Buzzer was not in the box, is not the end of the world, but happened. But real deception was when tried to use blocky, completely unusable with humanoid, if want to use arms there are errors on includes, same on wheels. I’m doing with arduino software, but I bought this for my doughter (7 years old) and is impossible to be done by her. By last, I bought “follow line” sensor kit, and I can’t found how to fix to robot. Some explanations will be good

Patience overcumes all things.
I have received all, but after a long time.

Thank you for a very positive learning experience. Your team has been friendly and supportive. I will definitely share the knowledge with others.

This very compact 16340 shield is awesome. There is no more need to buy disposable batteries. Therefore for the Humanoid Otto , I have found out you need even more power. May be the batteries I used did not have enough capacity. I have used the shield for 18650 battery from Diymore who gave me plenty of power.

A few minor parts arrived in a slightly damaged state but Otto replaced them instantly (and free of charge) and added support, suggestions, tips & tricks... all of their own free will. INCREDIBLE service and a fun product!

Great project kit fast shipping and the parts were perfect.

It is taking too much time to arrive and there is no estimated time of arrival. I cannot rate the product as it hasn't arrived yet.

I was expecting an easier experience for me and my young son. When we received the kit we struggled putting it together and finally realized that some of the pieces we had were oriented the wrong way. In the end we never got the robot together. It was a very disappointing experience.

Shipping was free, parts were good quality and well selected. Programming and building the robot was so much fun.

It's very useful and helpful for my daughter who is 6 years old.

It was very difficult to assemble, In fact it did not fit all together. Why do't you guys ship an assembled robot?
Kids can't do the assembly process by themselves so for them there is no learning in assembly.
I tried Otto Blockly on Windows VM on MacBookPro and it worked fine.
Also I lost the polarity of the buzzer and now there seems no way in the world to know which way the sticker said +.
I have not tried all the features yet for example buzzer, and arms did not work for me as of now.

Very rewarding experience! You can learn a lot with Otto DIY. I've built two with my 6-year old kid and it was lots of fun. In the meanwhile we both learn robotics and programming basics. The Otto documentation is clear and the community around the project is awesome!
