My design is for a backpack that can be carried around normally or can autonomously follow its owner. The bag has a three solar panels that can keep power to the bag or charge your phone or laptop inside the bag. You can carry it around, let it charge and then let it follow you., or you can just let it follow you all day. On a cloudy day the backpack can be charged at night by charging its removable battery bank with a USB-C connection. The backpack also has a tracker in case you lose it.
