These are very common questions that we have encounter through email, comments in other platforms and our Facebook group specially, This post is too put all of them together in one place, so new Otto Builders can have an "intro" of common obstacles and doubts to face with the most simple ways we have find so far to face them. (If you think there are some missing, please comment and we will answer them)
What is Otto?
Otto is your own personal robot you build and program. From beginners to advance, Otto has hundreds of functions that include dancing, avoiding obstacles, touch sensors, emotions, reacts to sound and voice plus much more. Anything is possible, because you make it!
Is Otto open source?
Yes! We provide all open source materials on Wikifactory. From 3D printed designs to coding functions other community members have made! We also have manuals directly on our website at: ottodiy.com/build.
What is Otto Academy?
Does Otto have AI?
What is the Otto App?
This is our free mobile application that allows you to control all movements, gestures and sounds of your Otto. Otto App is available for Otto Kit + and Humanoid. Check out our products at ottodiy.com/store.
Just got my Otto! Where can I find the manual to build?
All manuals are at: ottodiy.com/build. Just select the Otto you got and follow the instructions.
Maker kit comes with all the electronic components without the toy shell allowing anyone with a 3D printer to make their own Otto design. You can also use our open source designs made by our community of builders.
What’s the difference between Maker Kit and Builder kit?
Builder Kit comes with the toy shell including all the electronic components you need. This is popular for families who don’t have a 3D printer at home. This is all you need to get started, just the kit and your computer to begin programming.
I have never coded before. Is Otto right for me?
I am an experienced coder, what languages is Otto compatible with?
I am a teacher and want to do courses with my students to build Otto. How do I get started?
Awesome! Comes down to how many students you have. We recommend having each student with their own Otto to be more interactive as individuals. We also recommend using our courses from ottoschool.com to help fill your lesson plans. If your course requires a large order, we are happy to help with a discount. Just contact us here.
I have a 3D printer and want to design and print my own Otto, what software do you recommend?
How to install the Arduino libraries for Otto?
Answer: "If you use our new Otto Blockly visual programming you do not need to do this anymore, If you wanna use Arduino IDE software for learning advanced coding then there are multiple ways to add libraries to your Arduino IDE, after the software is installed the most easy for me, is to just Download all the libraries from the files tab and the unzip them to C:\user\Documents\Arduino\libraries (or wherever your libraries folder was installed)
You can also use the .zip installation through menu or even automatic updates online (i wish i knew how to do this for Otto) but we never did it this way, is a very general topic that all new Arduino users face.
Or we have a coding guide for that too!
How to find the right libraries for my robot?
Answer: We know there are many Otto Remix out there that created a challenge that we will be always working. To make them all compatible it does not seems possible with the current limitations fo the ArduinoNano flash memory, we tried... but that will requiere lots of libraries that would not fit into one micro-controller like the Atmega 328p, Then the solution was too separate them into different pages, projects, remixes etc. So depending on the Otto robot your are building just look into the Wikifactory, if you find libraries in the files tab that means you must use those ones otherwise just go with basic Otto, and we know... it is very troublesome having to delete the other libraries sometimes, otherwise it would not compile or the code could have errors due incompatibility between some Ottos.
Any other suggestions of how to handle this, please post on the comments.
Error when i upload a code, what does it means?
Answer: As mentioned in the previous answer Nano has limited memory is only 32KB of flash some codes specially the APP one for Otto DIY+ and Humanoid will show you an alert, you do not need to worry, if is just an alert saying that the memory is ALMOST full 90% so just play with the APP. https://www.arduino.cc/en/Main/FAQ
Another common error is the "avrdude: stk500_recv(): programmer is not responding" well is because you have the Bluetooth module connected while uploading a code, if is that the case you can´t because the module is occupying the communication ports.
Why my Otto does not precisely straight walk?
Answer: We have a blog post for this question that comes in different forms, even do the terms should be treated independently, First there is no such a super perfect never error straight walk even for million dollar biped robots, but we can get close to that only with low cost Otto by centering properly the motors; that is done in a mechanical way and MUST be done while building Otto, calibration instead is made electronically with code and is mostly optional, to achieve very precise movements. Please read this post that we have created to cover it all:
What Otto i am building?
Their instruction manual use same color as their heads simple! The most common Otto robot to start is the "basic green one" (https://wikifactory.com/+OttoDIY/otto-diy) from there you can have fun and challenge yourself to build others or create a new one! after you are confident enough you can jump to:
Otto DIY Laser Cut (https://wikifactory.com/+OttoDIY/otto-diy-laser-cut)
Otto DIY+ (https://wikifactory.com/+OttoDIY/otto-diy-plus)
Otto DIY Humanoid (https://wikifactory.com/+OttoDIY/humanoid)
Otto DIY Eyes (https://wikifactory.com/+OttoDIY/eyes)
Where to find list of parts?
Answer: We have been trying to tell the people that in our Wikifactory, you will find everything, we know Otto is spread out in the entire web, it helps to promote the project in multiple sites, but don't bother yourself just search in Wikifactory (https://wikifactory.com/+OttoDIY/) , if you do not find something or you have problems, just post an issue and we will solve it.
What to do with the touch sensor in Otto DIY+?
Answer: We have some predefined starter code, you can use to make Otto react to touch and for example make random movements you can customize. But you can do much more than just that, for example if Otto is touch too many times rapidly he gets angry if he is touch with long press, he will love you :D
How to use the LED matrix?
Answer: Tricky question, you can use it with the default gestures Otto comes with or create symbols, is an advanced component that we really simplify for beginners with our Blockly, but if you wanna learn more, google for Arduino Matrix 7219 you will find cool examples and please let us know if you find something that fits perfectly with Otto interactions.
Can Otto be controlled with an iPhone?
What battery can i use to power Otto?
That is all for now we are keeping updated this post, Do you think there is something missing? or we might need to expand to more questions? Please comment bellow.
