Terrano Tracked Robot
A connected tracked robot - controlled from a phone over Bluetooth, firmware updated remotely over the web (OTA), with live telemetry.
A video with phone control and OTA updates is coming soon.
The robot is built on an ESP32. It is driven from a mobile app (Flutter) over Bluetooth Low Energy or straight from the web over MQTT with about 50 ms of latency, its firmware is updated remotely over the web (OTA), and its status and telemetry stream live into a web dashboard.
