Abstract

Unmanned Aerial Vehicle (UAV) has proven to be a useful tool in many fields. UAV or quadcopter is equipped with a number of sensors and imaging systems that can perform various image-based things. This proves that quadcopter utilization can be allocated for a particular purpose, for example the purpose of reaching the landing mechanism. The landing is a phase that can cause fatal damage to the quadcopter if it does not land in its place. Thus the quadcopter is designed to automatically land on an object in various forms using the douglas-peucker algorithm. First convert the RGB color space to grayscale for easy to detect objects and eliminate noise using blur. Then it detects the edges of the object using canny and proceeds to search for the appropriate contour values ​​to get the edges of the object so that the quadcopter can recognize each object shape from the edge obtained and assisted with the object counting using the douglas-peucker method. Then it will be displayed on a frame that is divided into 9 grids and performs automatic movement according to the grid position until perform autnomous landing. Testing is done by testing the movement of quadcopter to detect object with speed 0,3m / s and 0,5m / s and test landing accuracy with height 125cm, 150cm, 175cm and 200cm. The results show that, at a speed of 0.3 m / s obtained the percentage of accuracy of good object detection is 100% and obtained the best landing percentage accuracy is 83.3% at 125cm altitude.

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

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.
