What am i doing l.jpg
What am I doing?

  • Would like to create an artificial intelligence

  • Needs a body, a physical presence

  • And a whole lot of learning

  • And a desire to learnDevelopmental Robotics

Bryn Mawr College

Institute for Personal Robots in Education


Developmental robotics l.jpg

What is thought?

What is consciousness?

What drives a system to want to learn?

How can we create such a system?

Developmental Robotics

  • I believe in strong AI

  • Such an intelligence may be quite different from our own

  • Will probably be as complex as our own intelligence, and just as hard to figure out how it works

  • Will lead to conscious systems, within 50 years

Pyro students are just now encountering CS and robotics?

  • Code for exploring robotics and AI, written in Python

  • GUI, libraries, abstractions, and collection of teaching materials

  • Robot, Device, OS, and Paradigm independent

  • Designed for beginning AI students to jump-right-in, but to also pedagogically scale as the user gains experience

  • A community of users, teachers and students
