The problem

In pandemic scenarios, such as the one currently at play, people want to minimize exposure to possibly contaminated objects, such as shopping carts. Having that in mind, we designed a solution that almost completely removes contact between user and cart.

What's the project?

• A simulated robot, in scale, to substitute a conventional shopping cart.
• The robot will communicate with the cloud server.
• The robot interacts with the app through the server.

Technical overview

Hardware project
