Controller and actuator of three independent DC motors In closed loop
Description :
This article describes a solution for a high power controller and
actuator of three DC motors in closed loop. This controller can be applied to
omnidirectional platform solutions using three motorised Swedish wheels as used
by several RobCup MSL robots and Minho omnidirectional Wheelchair. Some
exis...

Catadioptric system optimisation for omnidirectional Robocup MSL robots
Description :
Omnidirectional Robocup MSL robots often use catadioptric vision
systems in order to enable 360º of field view. It comprises an upright camera
facing a convex mirror, commonly spherical, parabolic or hyperbolic, that
reflects the entire space around the robot. This technique is being used for more

Mathematical model of welding parameters for rapid prototyping using robot welding
Description :
Rapid Prototyping is a relatively new technology that allows the creation of prototypes in a very short period of time compared with traditional manufacturing techniques. First, a model of the prototype is drawn, using a computer aided design program, which is then mathematically ‘sliced’ and used t...
