In this Paper, complete models of three and six phase self commutated synchronous machine drives are presented, considering the effects of both time and space harmonics. First, the equations for calculation of machine inductances are developed. Next, "thyristor-inverter-electric machine" set is modeled in order to derive all the equations for conduction and commutation states. Finally, the resu...

FALL 1998 21 Much of the work at the McGill Mobile Robotics Lab concerns computational problems related to use of sensors: vision, laser, and sonar. As a result, the McGill team entered the nonmanipulator category. The team was made up of four students: Francois Belair, Eric Bourque, Deeptiman Jugessur, and Robert Sim, with myself acting as faculty mentor. The robot they used was a NOMAD 200, a...

We describe a new experimental approach whereby an indoor flying robot evolves the ability to navigate in a textured room using only visual information and neuromorphic control. The architecture of a spiking neural circuit, which is connected to the vision system and to the motors, is genetically encoded and evolved on the physical robot without human intervention. The flying robot consists of ...
