Bidhushekhar

Bidhushekhar is a robot invented by Professor Trilokeshwar Shonku in the first ever Professor Shonku story Byomjatrir Diary written by Satyajit Ray. The robot was initially stupid, with limited speaking powers, however, sometimes it showed supernatural intelligence. It even suggested Professor Shonku the components of his Mars Rocket. In the surface of Mars, Bidhushekhar suddenly went out of control and went to attack the Martians. As a result Prof. Shonku was compelled to turn him off. Later in the rocket, when he turned it on, it started to talk in exteremly clear language. When the rocket was close to planet Tafa he told that the residents were extremely intelligent and advanced creatures. Upon arrival, this claim was found to be incorrect and Bidhushekhar hid himself from Professor Shonku.
