Otto DIY Builder Kit Product Help and Resources

Core Skill: Robotics

This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.

2 Robotics

Skill Level: Rookie - You will be required to know some basics about motors, basic motor drivers and how simple robotic motion can be accomplished.
See all skill levels


Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.

2 DIY

Skill Level: Rookie - Basic hand tools are required and instructions will allow more freedom. You may need to make your own decisions on design. If sewing is required, it will be free-form.
See all skill levels


Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Endless frustration, and still not working

I was familiar with Arduino from older projects, so I thought this would be a fun little kit to put together with my son. I still haven't gotten it working. A few problems: 1) The assembly directions are Ikea-level cryptic. There is an online set of instructions and a video, which I urge you to find (there's nothing in the box that suggests that there's more). These are crucial because, e.g., there are parts you actually have to cut to fit, and what you're supposed to do is completely obscure. 2) The 3D printing isn't particularly precise. I spent a lot of time filing pieces to fit. Like, a lot of time. The head is bowed in a way that means it won't snap on to the body. I had to cut down pieces further because they were blocking the cable channels. In addition to the included screwdriver, you'll want a pair of tweezers, a file, and some side-cutting pliers to get this together. 3) There are conflicting directions about calibrating the servos depending on which set of directions you look at. ("Move them to 90 degrees!" "Don't ever move them with your hands!" "It will work fine if you don't calibrate!" "Actually you should stop before you assemble this and upload this sketch to calibrate the servos") I can't say if this is actually necessary, as I still can't get it working. 4) Heads up, there is very little support for Macs. This kit does not include a bluetooth module, so you can't use the iOS app out of the box. If you have a mac you'll be dealing with Arduino's indifferent support for Macs, and then trying to get the online web editor working on top of that. Best I can tell, after an hour of debugging, it's also impossible to get this running on an M1 mac. And again, I used to do a bunch of programming on the Uno, so I at least have some sense of what might be fixed. If you have a mac and this is your first experience with an arduino, I wouldn't expect to ever get this running. 5) The base sketch blinks the nano's LED and also pulses pin 13. Since that's connected to the buzzer, when you plug this in you'll be greeted by an earsplitting series of beeps until you manage to upload a different sketch or (as I finally worked out) you disconnect the buzzer while you troubleshoot.

Finally, I should note that the first one of these they shipped didn't have the Arduino at all, though Sparkfun was champs about sending a replacement.

This has been a miserable experience. I should have picked a different option. I was leaning towards the BBC micro based bots, but my son thought Otto looked cute. But this is not an easy fun time with a kid. Pick something else.
