<p><em>Legged robots have attracted the attention of researchers because of their superior adaptation to complex environments compared to wheeled robots. Legged robots are divided into 2 (two) legged Humanoid robots, 4 (four) legged robots, 6 (six) legged robots, and other robots with more legs. Legged robots are robots that can be more adaptable to the terrain compared to wheeled robots in the case of their use in land exploration activities. Although functionally legged robots are more superior, legged robots have their own problems, namely motion control which is more complicated than wheeled robots, therefore the right method is needed to be implemented on the robot.. In this research discusses a 4 (four) legged robot designed in order to move using the inverse kinematic equation on the legs and the body of the robot which is integrated with the MPU6050 gyroscope sensor based on the Hybrid Fuzzy-PID control system. The purpose of this research is to develop a Fuzzy-PID control system that stabilizes the setpoint position in the 4 (four) legged Robot movement system. Fuzzy PID is a combination of PID control and fuzzy logic, where PID control is used to stabilize the system and fuzzy logic is used to improve the system performance. In this research, the Fuzzy-PID control system is developed using the Mamdani (Min-Max) method. The system is later tested by observing the robot's movement response to changes in the gyroscope sensor values. The results obtained were able to get an average output error up to 0.173333% during the response test to the pitch axis of -15°, but in several tests also get the response results that have a considerable error rate is up to 27.31% during the response test to the roll axis of -5°. From the test results of hybrid Fuzzy-PID control, it is obtained that the robot is able to make movements or responses to its stable point by giving reference to the x (roll), y (pitch) and z (yaw) axes where it can be analyzed that the response to the x (roll) and y (pitch) axes will affect the angle of the tibia and femur servo joints, while the response to the z (yaw) axis will affect the angle of the coxa joint servo.</em></p><p> </p><p class="IndexTerms"><strong>Keywords</strong>: IMUs (Inertial Measurement Units), Gyroscope, Inverse Kinematics, Hybrid Fuzzy-PID.</p><p class="IndexTerms"> </p><p class="Abstract" align="center"><strong><span lang="EN-ID">ABSTRAK </span></strong></p><p class="Abstract"><span lang="IN">Robot berkaki telah menarik perhatian para peneliti karena adaptasinya unggul terhadap lingkungan yang kompleks dibanding robot beroda.

<pre><em>Gout is the final metabolite of purines. Purines are part of the nucleic acids found in the nuclei of body cells. Increased gout can cause rheumatic pain in the joint area and is often associated with extreme pain for those exposed to the disease. Doctors need to monitor so that they can assist patients in monitoring and treatment. Gout detection devices are only available in hospitals, clinics, health centers, laboratories, and equipment that was previously portable but could not be controlled directly by a doctor. The purpose of this study is to help make it easier for doctors to monitor patients with gout remotely or telemedicine via the internet. The research method uses blood to determine gout levels using the Internet of Things. Data acquisition is carried out with a resistance sensor (Authocheck) which is processed by the Arduino microcontroller. The processed data is then sent to the ESP8266 web server via WiFi. The use of the Internet of Things as a data transmission method for online use does not require human-to-human interaction. The sensor resistance value in the analog range obtained is 441.03 to 782.32 with a sensor voltage of 1.91 to 3.82 volts. The measured gout level is between 4 mg/dL and 8 mg/dL. The percentage of measured data with an average accuracy of 95.74% and an average error rate of 4.26% for the seven test data. Data is displayed directly on the device's LCD screen and on a web server that sends data from the ESP8266.</em><em></em></pre><pre><em> </em></pre><p><strong><em>Keywords:</em></strong><strong><em> </em></strong><em>gout</em><em>, Internet of Thing</em><em>s</em><em>, resistance</em><em> sensor</em><em> (</em><em>A</em><em>utocheck</em><em>), telemedicine,</em><em> </em><em>web server</em></p><p><em> </em></p><p align="center"><strong>ABSTRAK</strong></p><p>Asam urat merupakan metabolit akhir dari purin.

<p>An incubator is a place designed to maintain a certain temperature condition. Incubators are often found in hospitals and farms. In hospitals, the Incubator functions to warm newborns, or premature babies. On farms, this incubator is usually used for egg hatchers and as a place for newly hatched chicks. Incubators are usually in the form of a room or box (box) of a certain size. In this research will be designed a prototype to modify the infant incubator by adding sensors to regulate the temperature and control using a Arduino microcontroller. This incubator has a measurement system and temperature regulation using LM35 sensors, heaters and fans as actuators that can cool the incubator room with Arduino as controlling. Temperature setting will be monitored by LABVIEW. In the Arduino system a program can be set up that can adjust the temperature . The temperature required by the premature baby, so that it can maintain the stability of the temperature. If the temperature in the incubator is smaller than the temperature setting, the heater will turn on and the fan speed will decrease to increase the temperature according to the settings entered. If the temperature in the incubator is greater than the temperature setting entered, the heater will turn off. The results showed that the linear regression value between the temperature values with the ADC value of y = 0.4883x with a determination coefficient of 1, while the linear regression value between the temperature with a voltage value of y = 99.481x with a coefficient of 0.9984.<br />Keywords: Infant Incubator, temperature sensor, LM35.</p>
