Abstract

Abstract-This paper describes the IMU sensor-based home search using a backtracking algorithm on a hexapod robot in the Indonesian fire fighting robot contest. The search for the homepage in this Indonesian legged robot contest is part of the robot's mission to achieve maximum points in the race. The algorithm discussed in this paper is a backtracking algorithm. Where the robot will return to the initial position by tracing solutions that meet the requirements. By using the IMU BNO055 sensor the robot will follow the direction that will depart then will guide the robot back to its home position. The results show that the backtracking algorithm is successfully implemented. So that the robot will still return home even though an error occurs when crossing the room intersection.

Abstract

The Indonesian Fire Fighting Robot Contest (KRPAI) has a mission to extinguish fires quickly, with various kinds of points and bonuses to be taken. The robot used in this research is a 6-legged robot (Hexapod). The problem faced today is the robot's ability to navigate the room, the robot still has to enter the same room, especially in room 1 (a room with 2 doors) so that the Arbitrary Start bonus or Variable Door location which prohibits the robot from entering the same room cannot be obtained. There is also a Room Factor bonus obtained using the JTS (Segment Distance) method which is an additional bonus when the robot walks outside the room. It is necessary to develop a room mapping algorithm with behavior based so that the robot can get maximum points. The main sensor used is the IMU BNO055 sensor as a robot direction orientation sensor, as well as a proximity sensor as a wall search sensor, so that the robot can know the direction when leaving and exploring the room, knowing the starting room, and ensuring the next room entered is a different room. The results of the test successfully made the robot take maximum points in the race.

Abstract

This paper discusses the implementation of a full state feedback control system on DC motors to stabilize the speed of DC motors and fight the disturbances given to DC motors. Modern controls such as full state feedback use 2 sensor inputs, namely the Hall effect speed sensor OH42E and the INA219 current sensor and use 3 parameters namely K1 (Constant 1), K2 (Constant 2), and KI (Integral Constant) in designing the controller, the goal is to get a good system response according to the desired design specifications. The test was carried out with a hardware-in-the-Loop (HIL) scheme which uses an Arduino microcontroller as a DC motor plant control device in the form of a control mathematical model entered in the Arduino IDE software and by trial and error to find the desired response value. The test results showed that at the values of K1=1, K2=1, KI=0.9, a stable system response was obtained with tr(s)=3, ts(s)=4, and Os(%)=7% The addition of an integral constant () value affects a short rising time but is inversely proportional to a high overshoot value as well. Varying the values of K1 and K2 as multipliers on the sensor values has an impact on the stability of the system response or oscillations. The stability of this system response indicates that full state feedback can be relied upon as a control system.

Abstract

This research describes the virtual humanoid robot R-SCUAD using the Gazebo simulator. In its development, humanoid robots often perform movements that have a negative impact on the robot's hardware, therefore the development of a virtual robot model is a solution to overcome this problem. So that the robot can be simulated before running. Gazebo is a robot simulator that allows to accurately simulate, design and test robots in various environments. Gazebo itself is a simulation used by ROS (robotic operating system). The simulation is built by doing a 3D design process in solidwork software and exported to a URDF file that matches the format on the ROS. Tests carried out on robots are by comparing virtual robots with real robots. From the tests carried out on the robot, it was found that the virtual robot can walk according to the real robot, such as falling if the robot's condition is not balanced. The simulation robot also moves according to the real robot when the controls are carried out.

Abstract

Hexapod robot is a robot that has 6 legs with joints or structures that resemble insect legs. This study uses the inverse kinematic method with the aim of finding points and effectors of the robot's legs that will make the robot's legs pass through uneven obstacles such as uneven flor, stairs, bolong-bolong obstacles, bolong-non-obvious obstacles and non-objective obstacles. This inverse kinematic is accessed with the Open Cm 9.04 microcontroller to control the dynamixel servo on the robot leg. The results of testing the robot's movement using inverse kinematics have succeeded in overcoming uneven obstacles using the inverse kinematic method. For testing the stability of the robot it is still not stable enough because the mechanical part of the foot is still not precise. The conclusion of the study, from 6 trials that average and uneven obstacles were obtained in the range of 85% - 95%. The inverse kinematic method using a proximity sensor on the front of the robot, the average success that can be obtained is in the range of 80% - 90%.

Abstract

In the Indonesian Search and Rescue Robot Contest in 2021 and 2022, the robot still cannot work well when passing through uneven obstacles. The change in uneven terrain from the previous year was a difficulty for the robot in passing it. This research was conducted to develop mechanical design and movement control design for the robot, so that the robot can be more optimal when moving through uneven terrain. The design of the hexapod robot is done by reducing the dimensions of the existing robot and determining the Center of Gravity point. The movement of the robot is also designed by determining the angular position of the AX-18A servo with respect to the terrain the robot travels through. The movement algorithm applied to the robot is the tripod gait algorithm. The robot control on the debris field and irregular floor is done by applying a proximity sensor to minimise the robot from hitting the wall on the field. The robot also has an IMU sensor that will work in measuring the slope on the up-and-down floor terrain (slope), so that the movement of the robot can be adjusted when passing through the terrain with the slope read by the sensor. The results of the research conducted show that the robot can be redesigned through 3D design through solidworks by determining the Center of Gravity (CoG) point. The robot has been able to pass through 3 objects tested, namely debris terrain, irregular floor terrain, and up and down floor terrain. The success rate of the robot when passing through debris terrain and irregular floor terrain is 100% with an average time of 9.7 seconds and 10.1 seconds. The success rate of the robot when passing through the up-and-down floor terrain is 80% with an average time of 22.9 seconds.
