Kawamura Laboratory
In general this laboratory aims for the fusion of the electrical energy and mechanical motion by electronic tools. They may call it "Mechatronics", but we wish to propose somewhat different concept, Motionelectronics - through our research activities.
The fundamentals are power electronics, actuator, and digital control. The tentative future targets are a new electric vehicle and a new biped walking robot.

Grants and Contracts
The laboratory has been receiving continuous support from Government, industries and University. The average research fund is $300,000-$600,000 (2000-2012).
You can receive the MSEE and PhD degrees from YNU, if you first pass the entrance examinations, and second earn the required credits and finally finish the required thesis. This laboratory can provide an opportunity for a very few foreign students to have a scholarship of Japanese Government (MEXT). Presently we have two MEXT scholarship students from South Africa and Tanzania, and two Malaysia government scholarship students (as of 2011/8). Seven students from Tunisia, France, Korea, Brazil(2), China and Turkey already finished their degrees. They received the Mombukagakusho(MEXT) scholarship.
