Tutorial: Moulding Flexible Links

Moulding Flexible Links

In this tutorial we will be designing a mould for a flexible link and making one with Sugru. With the link, you can join two other 3D printed pieces together.

This technique can be used to build flexible areas in a robot, allowing it to have more movements than being directly driven by a servo.

Check out the tutorial and try it out here.

Also see our Learn page for more tutorials and things to try 😉

Tutorial: Behaviours Using a Photocell

Behaviours Using a Photocell

In this tutorial we will calibrate the photocells (light dependent resistors), and create two basic behaviours for RoboBrrd to interact with you using the LDRs.

Reacting to light is one of the most basic behaviours that many animals have in common. It’s only obvious that we should make RoboBrrd have light behaviours as well!

Check out the tutorial and try it out with your own RoboBrrd here.

Also, we re-organized our Learn page- it’s much clearer now!

Hello, Botbait!

Introducing my latest robot to the world, a tentacle mechanism animatronic!


This robot is a great way to dive into the world of animatronic tentacle mechanisms and explore different ways of interacting with a robotic creature.

Also known as Botbait, this robot moves organically, lights up charismatically, and enjoys interacting with you.

Watch this video to see it in action:

It is available as a kit, a kit including electronics, and customised & assembled.

Building your own Botbait is a fun way to start getting interested in tentacle mechanisms while building a cool robot.


If you are interested in the ‘making of’, I went all-out with this robot’s documentation and created an in-depth video about the tentacle mechanism. It’s 17 minutes long, covering the design, building, electronics, programming, behaviour, and lessons learned.
