Project B.O.T - Bypass Obstacles in Transit - is a wearable safety and mobility aid device developed especially for the less mobile among us. It can help you navigate the Urban Jungle that cities are today by tracking where Obstacles like works, pole in the middle of the sidewalk, … are and helps you avoid them so that you arrive at your destination with the least amount of hassle. With the help of some IoT techniques (GPS, LoRa) and MQTT services we are able to receive and send data to the B.O.T. device. This data gets added to a version of OpenStreetMap.
Trough a simple interface and a 3 Buttons feedback People can easily interact with the device. A simple press on the GOOD button records a location where people feel safe (Good lit, Good Crossing, ..) A press on the BAD button records a location where conditions are not Ideal. A long press of the S.O.S. Button Sends out a message over LoRa to all the nearest B.O.T. devices, a message to the online Service, Sounds A loud alarm and Flashes its screen.
As B.O.T. is a low-cost device with only the function of helping people and always in connection to an online/emergency service it doesn’t attract potential aggressors so you can even keep it out and make it known that you have the device on you.
The base device we are using is an M5Stack, a modular open source ESP32 development board. This base is used and made extra sensor plates are made for example an extra loud speaker plate, also in the STL files.
There is an option to hard mount B.O.T. in the case or you could put in magnets in the base plate as some modules are magnetic.
