The Metropolis is a futuristic patrol drone equipped with a friendly holographic avatar that would be programmed to interact with citizens. Its avatar would look like ‘BIT’ from the TRON movie, and it would use an empathy module capable of recognizing and understanding human emotions.

The Background

I recently read an article about an empathy module being developed by Pascale Fung (“Robots With Heart,” Scientific American, November 2015). With the advances in robotic technology, we now have access to software and algorithms that can extract emotional cues from humans. The Metropolis, like the Interceptor motorcycle, is the natural evolution and integration of those technologies into future driverless vehicles.

How it works

The Metropolis would be shaped like a 5-foot-tall self-powered wheel. Its main function would be to patrol the streets and assist the public 24/7. It would be powered by a liquid-cooled electric motor capable of driving and recharging itself autonomously and zip between cars. Two internal gyroscopes would be used to veer left and right and keep the Metropolis upright when it’s slowing down.

The metropolis would use a holographic avatar to communicate with people around it. This avatar shaped like ‘bit’ would be located at the center of the wheel, approximately at the height of a car’s window. Multiple cameras equipped with eye tracking software would be built into the vehicle. Most importantly, the Metropolis would be capable of detecting human emotions by using voice analysis and facial recognition, and even connect with emotion-based API like the one created by Sensaura Tech.

Each avatar would react slightly differently since they would adapt based on their daily encounters with the public. Their voice tones would integrate local slang words and even be capable of humor. They would always be polite and friendly. Police officers would supervise small group of Metropolis, interact and guide them during their shifts. In fact, they could even become “friends” with each avatar and carry out conversations.

What it’s used for

Each Metropolis unit on the street means police officers can work on more important assignment. With their night vision cameras, infrared sensors, electric nose (to detect gas and chemical leaks), they will carry out their task with precision and efficiency.

The most important feature will be their artificial intelligence and avatar powered by an empathy module. They will be able to decrease tensions during events and choose the best course of action based on the past experience of all Metropolis.


The Metropolis concept was imagined in October 2015 by Charles Bombardier and the renderings were created by Adolfo Esquivel. Adolfo is a Colombian Industrial designer, currently attending a master in transportation design at the UQAM of Montreal. He works as a freelance industrial designer based in Montreal. Adolfo also created the design of the Nauki captain less sailboat and the Roxton amphibious ATV.
