HTR comes from the early foundations of field robotics, applied for space. Space robotics is an extremely challenging domain, currently in full evolution. HTR, with decades of accumulated prototyping experience, focuses on relevant pillars of space robotics, mainly planetary exploration. We pride ourselves for our ability to adapt and take up engineering challenges for these domains, maintaining our core principles of rigorous tests and design iterations for a successful study. HTR is based in Greece, maintaining subsidiaries across Europe to allow for easy collaboration with international partners. Over the past years we have focused on developing, patenting and commercializing an all metal, elastic, variable stiffness rover wheel for planetary exploration, managing to out-perform all similar wheels currently on the market. We aspire to provide our solutions to the fast growing Lunar Exploration economy.
