Personal Robotics will be to robots what Linux has been to personal computers.

BOB-303 Prototyping platform

BOB-303 was created because we needed an easy to use platform for our robot project that didn't break the bank. It is a way to use high end robotics software on a simple robot for learning purposes. You can get all the files needed to build your own on wikifactory, or you can support further development by buying our hand made kits.



Say hello to your new best friend!

BOB-303 is a classic biped robot based on the OTTO DIY design and all of it's spin-offs. However, BOB-303 is equipped with a Raspberry Pi Zero, providing a mount for the camera in addition to the distance sensors. BOB-303's head is easy to open with a hinge system, making the cables and batteries accessible for flexible prototyping.

BOB-303 has 6 degrees of freedom, using standard SG90 servo motors. 

BOB-303 is the perfect introduction to robotics for both children and adults willing to learn and experiment.


We love the environment. However, this is not the only reason why we choose wood as a construction material. Wood is tough and durable. It can easily be cut or drilled, and if needed, it can be glued with harmless wood glue. 
We use high precision laser cutting to shape the wooden parts needed to build the robot. The wood we use is 4mm beech plywood, which is extremely tough. 

The parts are still connected when you get them, so you don't get confused when assembling. 

Frequently Asked Questions

These are questions that we are asked quite frequently:

  • What does it do?

BOB-303 is a prototyping framework for your robotics project. You decide what it will do. BOB-303 has enough room in it's head for batteries, sensors and controllers. It is designed to fit the form factor of the Raspberry Pi Zero, however, you could use any microcontroller you'd like. 

  • But, can it walk?

BOB-303 has been designed with bipedal walk in mind. With it's 6 DOF legs, it is a great tool for studying simple walking techniques. 

  • who designed this?

BOB-303 is designed by Personal Robotics, however the design is heavily inspired by the OTTO DIY project ( 

  • But where is the software?

At the moment there is no software for you to download. We are working with companies and universities to find solutions to common problems, but in the mean time you have to do most of it yourself. 

  • This is so awesome! How can I participate? 

Build it and share what you've built. Write a blog/instructable/youtube video/whatever and send us the link.


Have fun learning!
