"Welcome to System and Control Engineering Laboratory Mechanical Engineering Department ITS"

Our main mission is to explore science, technology and social role of system and control engineering trough the utilization of robotics and maintenance management. The objectives of this mission is to replace human involvements in handling various industrial processes. The human behaviour, that seems unpredictable, unstructured, and uncertain become the obstacle that need to be overcome. We harness our members and partner’s collective skills and strengths and collaborated it into unique institution that is known as RSK Laboratory. Up until this point we actively involved in cross-discipline, cross-countries projects.

PARALLEL MANIPULATORS

RECONFIGURABLE PARALLEL MANIPULATORS FOR BUILDING

Reconfigurable parallel manipulators can be very efficient forthree-dimensionally printing complex shapes or overhanggeometry. The platform can continuously switch from one motiontype to another by using several solutions, i.e. belts, brakes,lockable-joints, etc. The reconfiguration process needs thoroughanalysis corresponding to kinematics and dynamics bahviour. This research can be seen in the video on THIS LINK.

GYROSCOPE

CONTROL MOMENT GYROSCOPE STABILIZATION OF UNSTABLE VEHICLES

The problem of stability of two-wheeled vehicle is very similar to the classic problem in control theory, namely the stability of the inverted pendulum. Conventionally, balancing the inverted pendulum is achieved by moving the base of the pendulum horizontally. This balancing method requires a large operating range of the moving base. A balancing system that allows the inverted pendulum to be stabilized on a much smaller area is a kind of balancer with inertial wheels or gyroscopic actuation. This research will formulate and prove the concept of controlling a two-wheeled vehicle which is analogous to an inverted pendulum with the gyroscopic actuation system.

CABLE ROBOTS

CABLE ROBOT WITH MOBILE CRANES

In an area affected by the earthquakes or Tsunami, search-and-rescue operation can be very difficult due to limited access. To address this problem, a cable robot with mobile cranes is developed. The boom of each mobile crane can be reconfigured which allows the robot to be more adaptable and robust. The works on static and dynamic equilibrium are required. The control strategy should be synthesized since the cable can only pull but cannot push.

SUSPENSION

ACTIVE VARIABLE GEOMETRY SUSPENSION

The suspension system is a component of the vehicle that used to isolate the vibrations rising from road unevenness. This research explore the potential of the Active Variable Geometry Suspension (AVGS) for comfort and road holding enhancement. The AVG Stakes a conventional independent passive or semi-active suspension as its starting point, and improves its behavior by actively controlling the suspension geometry.

PREDICTIVE MAINTENANCE

PREDICTIVE MAINTENANCE FOR INDUSTRI 4.0

Predictive maintenance for industry 4.0 is a method of preventing asset failure by analyzing production data to identify patterns and predict issues before they happen. Implementing industrial IoT technologies to monitor asset health and optimize maintenance schedules, allows manufacturers to lower service costs, maximize uptime, and improve production throughput.
