As the weather heats up and the school year nears its end, the time to don swimsuits and go to the beach or spend time at a park is drawing closer.
For those that don’t wish to carry around a bulky cooler with them while they participate in summertime activities, a pair of engineers have created the ultimate accessory in an autonomous cooler that follows a user via Bluetooth or GPS on a smartphone.
The cooler is powered by an Arduino Uno board, a 5V lithium-ion battery, HC-05 Bluetooth module, a GPS module and basic components found at most hardware stores.
The engineers used scrap and wood planks for the housing, basic wheels and a cheap cooler followed by the electronics. The robot cooler navigates by matching its own location to a user’s location by comparing GPS coordinates. It also has the ability to set a waypoint to the cooler so that it follows a path to another location without the user.
They configured a customizable Internet of Things (IoT) app to control the cooler with a list of simple commands, including a lid that automatically opens and closes through a command in the app. The cooler can be removed in order to carry other items such as beach towels, swimsuit bags or whatever you want.
