At BIT, Ranchi there are 11 I-Bot Robot.
These robots are made by triindia and build on a Philips 8051 microcontroller. However much to my annoyance, each robot is merely equipped with 2 sets of light sensors and can only be used for very simple experiments (viz.obstacle avoidance and line following).
The programming is done in C
These experiments are often included as a introductory robotics lab for postgraduate engineering students.
