MCU Net V2 — 
Applications for TinyML

MIT Hanlab is known for its tinyML (tiny machine learning) technology and software. Through a process called “Deep pruning,” they can compress their intricate neural network to an extremely small chip size, which lowers costs and increases efficiency in its usage. Dr. Han, director of MIT HanLab, asked Spatial Dynamics to design a series of electronic housings for his latest research development MCUNet V2, which uses an off the shelf microcontroller unit the size of an Airpod case. This series of products needed to illustrate different potential applications of the technology in order to demonstrate capabilities to investors.

Mask Detector

The Mask Detector is a wall mounted device that serves as a COVID safety checkpoint near building entrances. The device is mounted on walls and doors, and will only grant entry to visitors once it determines that they are wearing a mask. It is designed to be small and blend into the environment in order to not be visually disruptive.

Queue Tracker

The Queue Tracker is a friendly tabletop device that is a smart queuing assistant. One scenario  this technology can be used is in crowded places to keep track of how many people are waiting in a certain area. For example, in a waiting room, it can keep track of how many people are waiting, where you are in line, and how long the wait will be for the next person. This has the potential to create more efficiency and clarity in crowded areas.

Car Assistant

The Car Assistant is a helpful smart assistant that can adjust car settings according to the person that enters the car. For example, it can turn on the heat when a person comes in, or lock the car doors when the person leaves. The casing is designed to blend into the average car interior, and the suction cup allows the camera to be attached to most smooth surfaces, such as the windshield.

Process

The goal of these electronic enclosures was to show the vast application of the technology while emphasizing how small and simple the internal components are. In order to do that, we choose to use SLA clear resin 3D printing to fabricate the main bodies of these designs.

 

Another advantage of 3D printing these enclosures is that we can easily edit and print out new parts to satisfy different demonstration needs. The attachments designed for these cameras are magnetic, allowing for easy customization and attachment to other modules.
