Single servo robot

[Guilherme Martins] rose to a challenge to build a robot with a single servo. His robot is a puppet controller, called talkie walkie. In real time, it will move its mouth to the sound of what you are saying. For those really curious, he’s speaking Portuguese and he roughly says “Hi, how’s it going”. He’s using an Arduino with a custom sound sensor, a single servo, a box, and a folder paper mouth.

Building a single servo robot shouldn’t be that much of a challenge, we’ve even seen walking robots with a single motor. There’s this 2 legged crawler, and we recall seeing a 4 legged B.E.A.M. walker with a single servo, but can’t find it right now.

Vocoding with a piano

0210_klavier1_n (Custom)

This really cool project allows a grand piano to “speak”.  We don’t know any details about its construction but we had to share. The keys are being hit by solenoids in a manner to replicate human speech.  Click through to the video, it’s worth it. You may have to allow the popup to see the video, and it is in german, but the piano is clearly speaking english. We want one to keep around the office. It could read our emails to us.
