Halley: Ambassador Robot 001
A 2.6-ft laser-cut humanoid robot with 21 metal gear servomotors and an Android phone for a face, built to explore human-robot interaction and serve as a remote student proxy in university classrooms. Supported by a microgrant from the Frank-Ratchye Fund for Art @ the Frontier.
Overview
Ambassador Robot No. 001, also known as Halley, is a 2.6-foot humanoid automaton built for the sole purpose of exploring what it means to be human from a non-human perspective. The primary means of achieving this is through human-robot interaction, where Halley emulates as many human functions as possible while interfacing with another person.
A humanoid shape of respectable size is deemed necessary for authentic human connection, along with an array of face-to-face communication techniques:
- A speaker, camera, and microphone for basic sensory input and output
- Movable arms and legs to support gestures such as raising a hand to ask questions
- An Android phone as a face, allowing a wide range of expressive emotions to be displayed
The ultimate goal: to have Halley take the place of a student in a classroom — attending and recording university lectures as a remote proxy.

Recognition
The Halley Instructable received more than 23,000 views. Graduate students and a tech professor at various institutions expressed interest in replicating the project. The Poppy Project — a team of roboticists in France who inspired this work — were impressed enough to consider merging Halley’s contributions with theirs.
