Mohanarajah Gajamohan

Also known as Gajan Mohanarajah, Gajamohan Mohanarajah

Mohanarajah Gajamohan, who also appears as Gajan Mohanarajah, is a Sri Lankan roboticist whose cloud robotics work moves robot brainpower into the cloud. In 2001 he won a Japanese government scholarship, studied control and systems engineering at the Tokyo Institute of Technology, and completed a PhD at ETH Zurich in 2014. As a doctoral student, he led the Cubli project, a 15 cm cube that jumps up and balances on a corner, and served as technical lead of Rapyuta, an open-source cloud robotics framework built for the EU-funded RoboEarth project. Rapyuta Robotics, the Tokyo company he co-founded in 2014, raised 6.415 billion yen in a round led by Goldman Sachs in 2022. As of October 2026, he is co-founder and CEO of Rapyuta Robotics, which announced an end-to-end logistics solution built on its rapyuta.io platform in August 2026.

    The Cubli balancing cube

    In 2013, he leads the Cubli project at ETH Zurich and designs it with Raffaello D'Andrea: a 15 cm cube that jumps up, balances on a corner and walks across a desk. The project records more than 10 million views on YouTube.

  3. 2013

    Rapyuta, a cloud for robots

    The paper "Rapyuta: The RoboEarth Cloud Engine" appears at the 2013 IEEE International Conference on Robotics and Automation with him as a coauthor. He is the technical lead of Rapyuta, an open-source cloud robotics framework developed for RoboEarth, an EU-funded project to build a world-wide web for robots.

  4. 2014

    A PhD at ETH Zurich

    He completes a PhD at ETH Zurich in 2014, with research in cloud robotics and control systems. Raffaello D'Andrea supervises the work and Andreas Krause co-supervises it.

  5. 2014

    Co-founding Rapyuta Robotics

    In 2014, he co-founds Rapyuta Robotics in Tokyo with Arudchelvan Krishnamoorthy, his flatmate from their undergraduate years at the Tokyo Institute of Technology, as a spin-off from ETH Zurich. The company builds rapyuta.io, a cloud-based operating system that manages and coordinates a fleet of robots, keeping their brainpower in the cloud.

  6. July 2019

    A pivot to logistics

    In July 2019, Rapyuta Robotics, the company he co-founded, pivots its in-house solution to logistics. It completes a pilot of a pick-assist solution with Nippon Express, one of Japan's top third-party logistics companies.

From the biography.

  1. 11% of AI doctorate holders from 2010 to 2016 founded or led a company or lab by 10 years after graduationIncludes Mohanarajah Gajamohan. We estimate how often AI doctorate holders founded or led a company or lab by 10 years after graduation, how waiting times compare between founders and top jobs, and which universities trained the most.
  2. The median h-index is 48 at universities and 14 at frontier AI labsIncludes ETH Zurich. The median h-index is 48 at universities and 14 at frontier AI labs. We compare publishing careers, recent citations, dual appointments and job moves across 2,420 university researchers and 308 frontier-lab researchers.
  3. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other universityIncludes ETH Zurich. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other university. We compare doctorate and 5+ year employment links, career timing and current workplaces for 187 major-prize and 1,111 best-paper winners.
  4. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes ETH Zurich. We estimate where the people shaping AI worked when their most-cited papers appeared: the company share was 31% in 2020–2024 and 8% in 1970–1974, and Google led all organizations in 2020–2024.
