CO-ORDINATOR

2006


Objectives at cris l.jpg
Objectives at CRIS

  • Carry out fundamental research & develop prototypes.

  • Making Indian industries competitive by developing indigenous technology.


History of cris l.jpg
History of CRIS

  • CRIS came in existence in the year 1992. Earlier it was known as Centre for robotics (CFR). Prior to that there was an informal research group working in this then emerging area. This research group at CRIS has acquired in depth technical skills in design and fabrication of the robot manipulators, AGVs, devising intelligent control strategies for both manipulator and navigation and their real time implementations.
