Ankit Ravankar

I am a Project Associate Professor in the Department of Robotics at Tohoku University, Japan. I obtained my Ph.D. in Human Mechanical Systems and Design Engineering from Hokkaido University, Japan in 2015 majoring in autonomous mobile robot navigation and was a MEXT scholarship recepient from the government of Japan for my graduate studies from 2010-2015 (Masters and Doctoral).

I was previously affiliated with the School of Engineering at Hokkaido University in Japan where I was an Assistant Professor from 2015 to 2021 (same lab as my graduating lab).

My research areas are in mobile robot navigation, path planning, multi-robot systems, and probabilistic inferencing and scene understanding for mobile robots. I am particularly interested in integrating intelligent service robots in homes and healthcare scenarios by utilizing semantic inferencing at object level and generative AI that allows robot to handle complex tasks. I am currently working and researching on the development of mobility and assistive robots and multi-robot support systems for elderly and home care.

I have previously worked on several areas in robotics including: Field robotics/ search and rescue robots, Autonomous Driving in Snow Environments; Agriculture robots for vineyard monitoring, weed inseption, spectral imaging using UAVs; Aerial Robotics: For insepction of pier structures, spectral imaging of banana plantations, and inspection for coastal tetrapod rocks.
