An autonomous robot that detects toxic gases and human presence in mines; a smart PPE system that monitors workers’ health vitals and safety compliance; and an automated agricultural system that optimises irrigation while reducing water use were among the groundbreaking innovations presented by South Africa’s brightest young minds at the recent RoboRumble STEM Innovation Challenge.

Hosted by AlgoAtWork over four months, the student-centred competition sought to ignite technical excellence and bridge South Africa’s digital divide by equipping underserved youth with practical skills in robotics, coding, AI, and automation.

By promoting hands-on projects in IoT, robotics, AI, and automation, the competition allowed participants to hone their skills and gain the experience needed to thrive in a rapidly advancing technological world.

Sponsored by University of Limpopo’s UL Digital Hub, Engen and Sekhukhune TVET College, the RoboRumble drew more than 450 young innovators from KwaZulu-Natal, Gauteng and Limpopo, with just 37 of them reaching the grand finale which was hosted at the Sekhukhune TVET College in Limpopo, at the end of August.

Participants were tasked with conceptualising, designing, and developing technological solutions that address real challenges in the manufacturing, energy, and mining sectors.

The solutions had to focus on improving efficiency, safety, and sustainability through technologies centred on predictive maintenance, worker protection, automation, smart inventory management, quality inspection, real-time monitoring, waste management, autonomous transport, and environmental impact reduction.

Among the standout innovations were the following:

• Amajongo, a team of junior engineers aged 16 to 17 from the CHIETA Robotics Club (eThekwini Chapter), developed a predictive maintenance system that monitors machine operations in real time to prevent unexpected breakdowns. The system incorporates a DHT11 sensor to track temperature and humidity, as well as vibration detection. When readings exceed set thresholds, the system instantly alerts the user via the Blynk App. To give users greater control, a potentiometer enables adjustment of thresholds for temperature, humidity, and vibration. Visual feedback is provided through an LCD screen and LED indicators (green and red).
• Tech Mechatronics, a team of junior engineersfrom CHIETA Robotics Club in Babanango in northern KwaZulu-Natal, created a gas and smoke monitoring system for mines and chemical plants. Concerned about frequent gas leaks and explosions in South African mines, the team designed the system to provide real-time alerts, using both an onsite buzzer and LED as well as mobile notifications to authorities to ensure quicker responses.
• Socio Fix Solutions, a team of junior engineersfrom CHIETA Robotics Club, also in Babanango, developed BreathEasy, an industrial smoke detector and absorber system designed to cut toxic gas emissions from factories and mines. The prototype combines real-time monitoring sensors with a multi-stage filtration and gas neutralisation process. The system aims to reduce air pollution while protecting workers and surrounding communities.
• The Smart Safety Access Chamber (SSAC) from Sekhukhune TVET Collegedeveloped a smart PPE compliance system that ensures workers in mining, construction, manufacturing, and logistics environments are properly equipped. The system monitors helmets, gloves, and vests, checks vital signs including oxygen levels, heart rate, and temperature, and integrates a breathalyser to ensure workers are fit for duty before entering the field.

• Agri 360introduced an automated agricultural monitoring system that combines smart, data-driven irrigation with crop monitoring to increase yields and reduce costs. Using edge controllers (ESP32/Arduino) and solar power, the system automates pump and valve control, alerts farmers to irrigation needs, and responds to temperature variations such as heat or frost.
• Triple B: Robo-Bat Brigadeunveiled Robo-Bat, an autonomous, sensor-equipped safety robot capable of detecting toxic gases, fire, extreme temperatures, and human presence in underground mining environments. Using thermal sensors and WiFi, the robot sends real-time alerts, operates independently in extreme conditions, and enhances miner safety while reducing operational risks.

Apart from winning prize money, top solutions identified in the competition will be incubated through the Algorhythm Living Lab R&D Incubation Programme powered by Technology Innovation Agency (TIA).  In what is a departure from traditional robotics competitions, RoboRumble connects young innovators to long-term opportunities as participants also gain mentorship, entrepreneurial training, and exposure to industry partners.

This approach reflects AlgoAtWork’s ecosystem model, which aims to connect schools, educators, and industry leaders so as to help learners move to impactful enterprises.

Livingstone Mpahlele, the CEO of AlgoAtWork expressed satisfaction with the exceptional quality of entries received.

“What makes this Challenge even more inspiring is the fact that many of the brightest ideas came from young people in rural communities that are largely underserved. These innovators are proving that talent is not defined by geography. When we started AlgoAtWork in 2020, our goal was to provide young people with the tools, mentorship, and opportunities to shape the future. With RoboRumble, we are seeing that vision come alive and with continued support, these innovators will become leaders driving inclusive growth, job creation, and industrial transformation across the continent”.

Other Partners supporting the challenge included MLab, the Department of Science and Innovation, CHIETA, and Lethaba TVET College.

The RoboRumble STEM Innovation Challenge follows a structured four-phase format: RoboRise, regional makerthon and hackathon competitions for ideation and prototyping; Hackathon Ultimate Eliminations; RoboCode, a one-month support programme; and the RoboRumble Grand Finale Showdown. Problem statements are drawn from actual industrial challenges, requiring participants to use tools like Wokwi, the world’s most advanced ESP32 simulator software, to develop their prototype kits.

Through this initiative, Africa’s youth are demonstrating their ability to create practical, technology-driven solutions that enhance safety, efficiency, and sustainability. The RoboRumble STEM Innovation Challenge continues to position young innovators at the forefront of Africa’s industrial and technological transformation.

Looking ahead, AlgoAtWork is already preparing for the 2026 RoboRumble, which promises to be bigger and more exciting. AlgoAtWork envisions that RoboRumble will become a flagship innovation talent platform that will extend to all provinces and serve as a launchpad where industries and youth co-create solutions for the digital economy.
