A full Project wright-up and instructions coming soon!
LiTeRo, short for Little Telepresence Robot, is a DIY Raspberry Pi powered robot that can be controlled from any web browser from anywhere in the world. We wrote a single Python program in conjunction with a lightweight AJAX-style communication standard to achieve extremely low latencies with relatively few software dependencies.
LiTeRo is as a do-it-yourself project is designed to be exceptionally modular and customizable. By default, it was designed to sport a wide angle Raspberry Pi camera, High-power IR navigation LED, 9-DOF IMU, 4Ah LiPo battery (with monitoring), and a roll-in charging dock. Also incorporated later in development was a method for verbal communication. That’s right, LiTeRo can speak nearly 50 languages with the eSpeak Text-To-Speech (TTS) engine! Other TTS software packages for the Raspberry Pi can also be implemented with relatively minor revisions to the Python program. The robot can also sport a number of 9g servos for basic environment manipulation or for self-righting maneuvers.
