Africa’s engineering talent converged on Hartebeesthoek as 18 finalist teams deployed self-built rover prototypes across the South African National Space Agency Mars Yard for the Cars4Mars African Rover Challenge final, testing autonomous navigation and remote traversal missions.
The Mars Yard at the South African National Space Agency site in Hartebeesthoek transformed into a high-stakes testing ground as emerging engineering talent from across the continent put their custom robotic systems to the test during the Cars4Mars African Rover Challenge: Mars Stage Final 2026. Around 120 young participants representing South Africa, Kenya, and Zimbabwe arrived for the physical final after advancing through an initial online stage that drew approximately 100 teams from 11 African countries.
The five-month competition, which kicked off on May 1, 2026, challenged students and learners to design, engineer, build, test, and refine their own rover prototypes before bringing them to Hartebeesthoek for the ultimate evaluation. The event’s obstacle course was constructed using more than 40 tonnes of red sand sponsored by Afrimat, successfully replicating the desolate appearance and rugged terrain of the Martian surface.
Rigorous Missions Test Autonomy and Remote Traversal
The competing rovers faced two primary evaluations: the Traversal Mission and the AI Autonomous Mission. During the Traversal Mission, student teams remotely operated their machines across uneven, challenging terrain to locate and transport objects placed on the course by judges. Operators could choose between camera-based visual feedback and direct observation, putting their remote-maneuvering skills to the test.
The AI Autonomous Mission pushed participants to apply artificial intelligence and computer vision to their robotic systems. Teams had to identify specific objects within their rover’s camera view, including a hammer, a tennis ball, a traffic cone, and balloons of various colors, with bonus points awarded for systems capable of calculating an object’s precise location within the camera image using AI or computer-vision algorithms.
Today was a wonderful reminder of what young people can achieve when they are given the opportunity to build, test and solve real challenges. We saw wheels come off, AI vision systems struggle to recognise objects and teams having to adapt in the moment but they kept going.

Industry Backing and a Permanent African Mars Yard
The partnership between Cars4Mars and SANSA establishes Hartebeesthoek as a permanent venue for future competition finals, creating a lasting platform for young African engineers and space enthusiasts Spaceinafrica.
A wide network of sponsors supported the event. SMD Technologies provided Creality 3D printers for the podium-finishing teams, while RS South Africa supplied electronics vouchers.
Global Context in Desert Analog Testing
The African student showcase runs parallel to broader terrestrial Mars simulation efforts worldwide. In Southern California, NASA’s Jet Propulsion Laboratory recently tested its Exploration Rover for Navigating Extreme Sloped Terrain (ERNEST) prototype across a 16-mile desert trek lasting over 37 hours of driving time.
Similarly, analog testing grounds in places like Hanksville, Utah, bring together student competitors and researchers to evaluate equipment against geological conditions that mimic planetary bodies through targeted equipment servicing and science missions. While analog sites on Earth cannot replicate lower planetary gravity or deep cold, these desert environments provide critical proving grounds for the mobility hardware and autonomy software that will shape future interplanetary exploration.
