Here is a cool project update from John on the start of a robot that uses flexible links! Nicknamed Flexibot 0.1, here you can see the flexible links in action for a pan-tilt head, controlled by a RC joystick:

Here’s more thoughts from John:

One thing I’ve been thinking about for years, is flexible robots. I’m a pretty good fabricator, but the precision and complexity, required to make useful multi-degree of freedom joints (like your shoulder) has always seemed a little daunting, especially if you try to make them compact.



He plans to go further on the mechanics, then turn it into a proper robot with autonomous control. Last update on Twitter, he’s going to the hobby shop for more parts- so that will be interesting. 😉 Botbait is definitely looking forward to (virtually) meeting another flexi-bot!

Botbait Update

Here’s Botbait watching a new fellow bot being created!

Botbait appeared on the MAKE blog the other day:

We have heard some interesting feedback from people-

If you wanted to build your own tentacle mechanism tail (without the top pieces, but with more vertebrae), there is now a bundle HERE for $29.95.

One of the most common questions is: Is it hard to make?
Botbait is challenging, but it is possible to make it. We are currently working on the instructions, but it will serve as a useful guide for anyone looking to make one. There is also the in-depth video.

From wondering about how cats would react to this robot, to imagining creepy alien designs for Halloween, to how they can react to Gangam Style, it has been fun to hear the feedback.

We sold our 1st Botbait kit yesterday, and are printing the pieces as we type!


Who will be the 2nd kit? They are available in the store now 😉

THANK YOU to everyone who has shared about Botbait on their social networks. It really helps spread the word and reach more people.

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.
