A Mars Rover Explores my Backyard
In this review, we’re taking a look at the SunFounder GalaxyRVR Mars Rover, a departure from their Raspberry Pi-based kits. Instead, the Mars Rover utilizes an Arduino Uno for its control system. The kit comes pre-programmed with the Arduino firmware, allowing for immediate use with the SunFounder mobile app post-assembly, without the need for additional software installation. Priced at around $175CAD, it’s a budget-friendly option for robot enthusiasts.
Assembly of the Mars Rover is relatively straightforward, with clear instructions and easily identifiable parts. The kit includes 37 steps, assuming the optional solar panel is installed. While there are six motors to install, the process is simplified without the need for zeroing or calibration, unlike servo motors. However, some users may encounter issues with servo calibration, easily rectified post-assembly.
Operation-wise, the preprogrammed Arduino Uno interfaces with the SunFounder mobile app. However, unlike Raspberry Pi-based robots, the Arduino creates its own GalaxyRVR Wifi network, requiring manual connection from the user’s mobile device. This setup may cause connectivity issues, particularly on iOS devices, due to the network’s lack of internet access. Despite these drawbacks, the SunFounder app provides a convenient dashboard for controlling the Mars Rover, complete with a live feed from the rover’s front camera.
