RIVERFIELD Inc. CEO Kotaro Tadano made the following remarks:
We were founded in 2014 as a start-up company from the university, and have pushed forwardwith the development of surgery support robots based on technologies cultivated at the university.
For surgery support robots to this point, issues such as the inability to sense force during operations,and high introduction and operational costs have been identified.
By means of the low-cost provision of surgery support robots that enable force adjustments throughthe use of original drive-control technology using pneumatic force and the wide diffusion of theserobots even to hospitals of medium size and smaller, we aim to deliver the benefits of robotic surgery
to a greater number of patients. On this occasion, it is very reassuring to receive supp ort from Daiichi Life, which has made many ESG investments to this point. Moving forward, we hope to utilize
remote-controlled technologies.
