Rovy Part 3: Initial outdoor tests with onboard 4G/LTE modem and sensors

Vince Elizaga — Mon, 30 Oct 2023 22:02:18 +0000

We’re now moving on to the third phase of the project, which involves the integration of an onboard 4G/LTE modem to enable remote outdoor mobility. Additionally, a new set of sensors has been introduced for telemetry transmission via AWS IoT Core using MQTT.

The testing also extends to outdoor conditions, providing valuable assessments of the data gathered from temperature, humidity, GPS (including coordinates, speed, and altitude), IR range, and battery voltage during the rover’s full-load operations.

Rovy Part 2: Video stream from onboard camera using AWS KVS

Vince Elizaga — Sat, 14 Oct 2023 21:03:03 +0000

Overview

This is the second part of the project that tackles on sending a video stream from the rover's onboard camera through AWS Kinesis Video Stream (KVS) using the WebRTC communication protocol.

If you want to dive right away into the code, you can check it out here:

Rover Hardware (branch -> rovy-part-2)
Mobile App (branch -> rovy-part-2)

I will be pushing updates to the repositories as I add more things (i.e. sensors) into the rover as I progress in the future, so the main branch might look different by the time you are reading this. As for this article, please refer to the specified branch.

I have a full write-up of this in my blog. You can check it out here here.
