CURRENT PROJECTS
CABLE-DRIVEN parallel ROBOTS
A cable-driven parallel robot uses cables to drive the end-effector instead of conventional rigid links. Cable-driven robots can cover large workspaces with high stiffness, lower inertia and at a much lower cost. However, these robots experience nonlinear vibrations and cable slack resulting in loss of precision. This research tries to address these challenges.
metal additive manufacturing
Parts fabricated using metal additive manufacturing suffer from residual stresses and distortions due to large thermal gradients. This research focuses on control of the manufacturing process to achieve a more homogenous temperature distribution.
3D printing in hostile environments
Stocking of a large number of parts to avoid downtime can be avoided using 3D printing. However, 3D printing in hostile environments can still be a challenge. This research tries to address challenges associated with 3D printing in hostile environments.
PRECISION MOTION POSITIONING STAGES
Precision stages are used to achieve high precision positioning. To achieve high repeatability and accuracy in precision stages, this research will focus on modelling and control of these stages.
3D Printing
3D printers have the ability to revolutionize manufacturing. They have the ability to fabricate customized and complex parts. This research focuses on improving quality and productivity in 3D printing through use of motion and process control.
