Story of

Wassim El Hariri

Hospital Patient Food Delivery Robot

“We have a responsibility towards all the young innovators willing to make a change. We need to improve the economy and life in general and create a sustainable planet – it’s a big responsibility for all of us.” Says the innovator Wassim El-Hariri, who participated in the Stars of Science season 9. 

Project & Impact 

Wassim’s mechanical expertise is deeply rooted in artificial intelligence. During Stars of Science, he developed a device to deliver food from the hospital kitchen to the patient’s bedside. Wassim’s Hospital Patient Food Delivery Robot increases hospital efficiency by freeing up medical staff’s time and ensuring that patients are served meals quickly and safely.

Aftermath of SoS

Wassim worked as an International Project Manager in Berlin, Germany. He then started his own company called Revotonix, the first mobile robot company in the region, working between Lebanon and Germany. Revotonix makes customized mobile robots and gives advice on robots. Their first product is Felix, a robot that can show ads based on the viewer's age and gender.

Wassim won three competitions with his robot SASHA, which delivers food to hospital patients. One of the prizes was the Tech-I Competition from the U.S. Department of State, which gave him over $50,000 in start-up resources.


In 2019, he sold his robot SASHA to a Belgian company. His product is ZenZoe, a robot that can decide where to go to disinfect areas using UVC technology. This robot was made in response to the Covid-19 pandemic.

After the pandemic, his company started making software, specifically navigation programs for mobile robots. His company partnered with a big robotics company to use its navigation software.

Most recently, in 2023, Wassim launched a new product: “Stack Tech Farm: A 3D Autonomous Stacked Farm Powered by Mobile Robots & Flexible Autonomy” an innovative solution to global food sustainability issues through the development of affordable, ultra-dense urban farms. By employing a pioneering cultivation technology called the 3D autonomous stacked farm, they optimize operations and significantly cut costs. With the use of ultra-high-density farming and micro-robots, these farms can potentially quadruple production compared to traditional vertical farms while enabling a wider crop variety.
