Abstract

Remotely Operated Vehicle (ROV) is an underwater robot that designed by UNTAR Robotics Team and has been competed in Singapore Robotics Games (SRG) 2020. Evaluation that conducted from the competition is the need of optimization in thrust and maneuverability so it can move more flexible and stable. Based on the problem, investigation of thruster’s configuration by adding kort nozzle to existing propeller is implemented to increase thrust and performance. Consideration in using open water characteristics for analysis is elaborated in this investigation. The existing propeller has 3-blade with 35 mm diameter; 1,4 pitch diameter ratio; and 0,511 expanded blade area ratio which is used as thruster of ROV 2020. It utilizes CFD approach in ANSYS CFX 2020 R1 software with moving reference frame (MRF) method. Meanwhile, general mesh or unstructured mesh arrangements is used as computational mesh with 165.201 nodes. The MRF implements frozen rotor concept as frame change/mixing to observe fluid flow. The CFD with shear stress transport (SST) k-omega model is conducted. The simulation is done at 300 rpm and J = 0,473 for ROV’s operating condition. The result shows that thruster equipped by kort nozzle is able to increase the thrust for 2,253% and reduce the propeller required torque for 6,633%. Furthermore, the configuration can also reduce wake phenomenon as result of rotating propeller which represents better maneuver chance. Keywords: ROV, kort nozzle, open water characteristics, CFD, performanceAbstrakRemotely Operated Vehicle (ROV) merupakan sebuah underwater robot yang didesain oleh Tim Robotik UNTAR dan telah berkompetisi dalam Singapore Robotics Games (SRG) 2020.

Abstract

In the industrial era 4.0 where the development of sophisticated technology, the development of technology has been increasingly rapid. The industry itself began to use this sophisticated technology with the aim of seeking maximum profit with minimum capital, so for that reason the industry began to switch to "Industrial Automation". With the aim of understanding the complicated production process, MPS (Modular Production System) is made with the aim of facilitating understanding of the related production process where the MPS to be studied is Pick & Place Station. The method to be used is an experimental method where what will be studied is the effect of flowcontrol openings on cycle time, the effect of flowcontrol openings on flowsensor data, vacuum lift force, vacuum force using the venturi principle. Where the greater the flowcontrol opening, the faster the cycle time will be with the risk of cylinder damage where the first entry group produces a slower cycle time than the cycle time produced by the second entry group. The flowcontrol opening itself also affects the data in the flowsensor where the data for average mass flowrate, average flow velocity, average volumetric flowrate, average temperature, and average pressure shown by data entry 1 is smaller than data entry 2. The vacuum lift force for entry 1 and entry 2 has the same value or there is a very small change for both the distribution station and the pick & place station. For vacuum force with the venturi principle, data entry group 1 produces a smaller force than data entry group 2.

Abstract

In the industrial era 4.0, the automation system technology used is growing rapidly. Automation systems in the industry are very useful, especially in reducing production time. One of the tools that can be used to simulate production in an industry is the Modular Production System (MPS). MPS itself consists of several stations to simulate the production process on a small scale. In a production system, of course, a system is needed that can detect abnormal workpiece conditions. This system will be driven by a Programmable Logic Controller (PLC). This system will be placed at the distribution station. The rejection system in MPS is needed because, in MPS there is still a manual process, namely in the process of inserting workpieces into the stack magazine. with this manual process, it is likely that workpieces with abnormal conditions will be processed by MPS. This condition is unlikely to be processed further to the pick and place station. Therefore, objects with abnormal conditions must be separated by this rejection system. There are 2 methods used to conduct this research, namely using the 5/3 valve and the positive stop method. Data collection from both methods is done by experiment. From the experimental results of the two methods, it can be seen that the best method used for this system is the positive stop method. This method is the most appropriate method because it can produce a very accurate swivel arm stop position. From the data obtained, using the 5/3 valve method with a pressure of 4 bar the swivel arm stop position ranges from 22.4 cm to reach more than 25.8 cm, and at a pressure of 5 bar the swivel arm height ranges from 25.8 cm to more. By using the positive stop method the swivel arm stops exactly at the specified swivel arm height because the swivel arm is held by the pneumatic cylinder.

Abstract

A robot arm is a robot component in the motion subsystem of a robot system to determine the position and orient the object so that the robot can perform certain tasks, such as picking and placing an object. To use it as a pick and place, a gripper shaped like a human finger, commonly called a jaw gripper, is required, which is used to hold, tighten, hold, and release an object. The shape of the jaw gripper is designed and made according to the shape of the workpiece to be grasped, which was created by PT Matahari Megah using the 3D-printing method for its customer. The jaw gripper that has been designed still needs to be developed to produce a more optimal jaw gripper design, such as by reducing the use of excessive filament without reducing quality and minimizing costs incurred. Therefore, a more optimized jaw gripper test tool was made with a material reduction method using the generative design process in Inventor software, and physical testing was carried out on the ability to grip and deflection, compared to the testing process using a test system that had been designed with a dial gauge measuring instrument. The results of the comparison between the Inventor software results and the simulation results do not exceed 10%, with the difference at a pressure of 2 bars of 7% and the difference at a pressure of 4.6/5 bars of 1.87%.

Abstract

Nowadays, the application of automation in the manufacturing sector is important to increase production efficiency. One of the variations in industrial automation is the vacuum gripper. Vacuum grippers are specifically designed to handle specific workpieces, such as labeling application. Label characteristics that easily bend and stick to the workpiece when peeled off require a specific gripper. This research was carried out using 2 methods, experimental method and CFD simulation method. The experimental method was carried out by collecting pressure data with Arduino. Data from this experiment will be used for the CFD simulation. Based on these experimental tests, the average vacuum pressure obtained was -44.372 kPa. From the simulation vacuum pressure on the 12 inlet holes was obtained. The largest vacuum pressure was at inlet 12 with a vacuum pressure value of -44372.11 Pa, while the smallest was at inlet hole 1 with a value of -44371.86 Pa. The pressure distribution is evenly distributed at all the suction point and has suited the design requirements.

Abstract

Modular Production System is a station unit consisting of industrial components in the form of pneumatic and electrical components controlled by a Programmable Logic Controller which is directed for industry-oriented vocational training. In a Modular Production System, there are several types of stations, one of which is the pick and place station which consists of two modules, namely the pick and place module and the conveyor module. This design discusses the optimization of the design of the top cover feeding unit at the pick and place station because the top cover is dislocated every time there is a change in position when the vacuum sucks the top cover. This design optimization is done by redesigning the feeding unit slider. By doing this optimization, it can make the feeding unit accommodate the top cover where it should be and improve the process capability of the system. The results of this optimization are determined based on the process capability values, before optimization the resulting values were 1.0417 for Capabiity Process and 0.77 for the index. Then after design optimization, the values are 3.402 for Capabilty Process and 6.396 for the index and produce a total force of 0.205 N by using a slider feeding unit tilt angle of 14o. This tilt angle was determined as the most optimal angle because it resulted in the least system failure.
