Systems and methods for programming an embedded system include establishing a first communication link between a user device and a remote multiplexer, and a second communication link between a single-board computer and the remote multiplexer. In some embodiments, the user device executes a web browser that provides an application interface. By way of example, instructions for operating the single-board computer are received at the remote multiplexer from the web browser. In some embodiments, the remote multiplexer also receives a first identifier that identifies the user device and a second identifier that identifies the single-board computer. In some cases, the instructions and the first identifier are transmitted from the remote multiplexer to the single-board computer based on the second identifier. In various embodiments, the single-board computer is configured to execute the instructions and control a robotic device within which the single-board computer is embedded.
