Picture of GoonQuad, an Emotive Quadruped

Hi everyone

This week our students from Computing in the Creative Arts had a public exhibit of their term projects. This project is close to my heart as I worked closely with this particular group of students who despite having very little technical background were deeply passionate about creating an interactive robot capable of expressing emotions and interacting with people.

The students involved were
Lauren Abramsky [portfolio]
Kristy Titanic [portfolio]
Jesse Shaw [portfolio]

The instructors were
Antonio Gomes (myself) [portfolio]
Paul Strohmeier [portfolio]

I have submitted this project to the robots and arduino contests. If you like it, your vote is appreciated :)

I present you "Goon Quad". In this version, Goon Quad has 4 prerecorded states ("angry","party","confused","breathe"), triggered by the touch of a person in areas specified by the eyebrows and a tattoo that read "Mom", painted with bare conductive and used as capacitive sensors.

My students just finished editing their video! Cheer them up with some comments and likes on YouTube :)

To enable the robot to record new motions, 8 analog feedback servos were used. As of now, we are only using one leg to record and translating it into the remaining 3. v2 will feature a fully programmable robot. Here's an example of the recording motion in action (arms and base video below)

In the step by step I will provide all the .stl files and early iterations of the robot. Assembly should be self-explanatory by looking at the images but if anyone as any questions or requests for laser cutter friendly formats I am happy to provide those. Just leave me a note in the comments section!

Hope you like this project and feedback is very much appreciated

What i do not understand: What is that box for? A little more explanation for everything would be great. I really would love to do this projekt :-)

I only have access to a cnc mill so ai files would be great ..

Really nice project

i don t understand exactly how is fixed the "hand arm mount" and in the zip file it's a plate to print not the piece.

Thanks for pointing that out.

I have uploaded new stl files/instructions. Let me know if you have further questions :)

I will be one of the contributors for your Kickstarter project. Hint...Hint.

Your comment made my day!

I wish I had the time and resources to consider it but a kickstarter over a project i can share and grow through instructables is definitely on my mind :)

u do realise that it cant turn right
antpgomes (author)  muddu111 months ago

that was hardly the scope of this project although modifying it to a walker is trivial.
