Abstract

Currently, criminal rate in the world is increasing because the difficulty of getting work. One of the highest criminal case which we often heard is the case of people abduction or the case of missing people. To reduce this problem, I created a low power location tracking in wearable device for people, location tracking system is designed as small as possible so this device could be carried by the person while they're going. This system used U-Blox Neo 6M, SIM 800L, Arduino NANO, and a power bank. U-Blox Neo 6M used for the location tracking with GPS network, SIM 800L used to deliver coordinates to the tracker via SMS with GPRS network, Arduino Nano used to configure input process and output process from the system, and power bank as the primary resource which the system used. This system is filled with sleep power mode feature that became the method for the system manufacture which functioned to save the usage of the power when the system is working. Tracker could know the position of the user by writing down a predetermined keyword via SMS to the number that used by system. With this sleep power method expected to be capable of having a longer power usage and capable of reducing the case of missing people.

Abstract

The world of robotics is now constantly developing. In Indonesia the government strongly supports the world of robotics with the holding of various kinds of robotics competition which one of them is Indonesia Robot Contest. In the contest there are various kinds of robots that are contested one of which is the Indonesian Fire Extinguisher Robot Contest where the robot must walk in the match arena to find and extinguish the fire. Today many robots use the hexapod or 6 foot robot concept with wall following as the maneuvering algorithm. But with robotic design robot hexapod must do 90 degrees rotation when there is a hitch in the front so need more time. For that required a robot design that can perform maneuvers properly and quickly. So to overcome these problems, in this research do the implementation of wall following algorithm on robot maneuver quadruped omni direction by using fuzzy method for robot decision making. With the design of robot quadruped robot is possible to maneuver in omni direction so that the robot does not need to rotate and get results faster. From the test results obtained robots who perform maneuvers omni direction is faster than the rotating robot maneuvering with the average speed difference of 4.1 seconds. The robot can run and can maneuver well using wall following algorithm and fuzzy logic with 100% success rate.

Abstract

While error appears, it can be a mistake for the information. The emergence of error caused by many factors, for example the presence of noise in the data transmission medium, time of use of the hardware, or the quality of the hardware. One of concepts called information redudancy is a concept that inserts additional information on the process of encoding data before the data transmitted. Information Redundancy can be applied to the process of error control coding, which is technique that enables the encoding process to calculate additional control bits from the information, and to transmit these control bits and their information. In this research, using Hamming Code method to applying in Arduino and UART communication. The Hamming Code method is a method that add an additional bits to the data bit by using XOR logic on the process. In this research, Hamming code method can do the process of encode and decode, and can perform the detection and correction process on data that have errors in the testing process. The average delay for 5 bit data is 102.7m/s and 109.5m/s for 4 bit data in the encode process. In decode prosess, 17.5 m/s for 10 bit data and 100,1m/s for 11 bit data. Temperature data retrieval and the number in the encode and decode process can be a factors that greatly affect the encode and decode process using the Hamming Code method.

Abstract

One of the obstacles in industrial robotics is reducing errors between robots and target points because it has a great impact in the accuracy of a robot. To improve the accuracy, optimization of existing methods is needed. Kinematics is required by industrial robots to calculate the angle to get the specified position. To find out how much angle needed, Inverse Kinematics method is used by putting the target point into the calculation then the result is the angle to be reached by each joint. But, in reality, after the resulted angle being put again in Forward Kinematic equation, the result is not the same as the initial target. From this problem, Cyclic Coordinate Descent (CCD) method is created to solve it. CCD method works with iterative approach, which moves the joint one by one based on the distance of the end-effector to the target. Results from experiments using SCARA robot and 2 kinds of testing showed that CCD method could reduce the average error between end-effector and target up to 20% than Inverse Kinematic method. However, CCD method requires 0.31505 seconds longer than Inverse Kinematic due to its iterative behavior. From the results, it can be concluded that the CCD method with SCARA is effective enough to reduce the accuracy error when moving to the target position.
