Abstract

Robotic technology that is developing rapidly triggers robotics developers to improve their abilities, especially in the field of robot control and monitoring. Today, robots are indeed present in human life in various forms. One type of robot that is often developed by robotics developers is the Industrial Mini Manual Robot. An industrial mini manual robot is a transporter robot that is equipped with a gripper and is controlled manually by the user through a joystick controller both wired and wireless. The manual robot with cable joystick control is very inefficient in its use so research on wireless joysticks is carried out. However, the current wireless joystick still uses the single-channel method, thereby eliminating multitasking capabilities such as those of the wired joystick robot. In this research, the design of multichannel transceivers for control and monitoring so that the robot has the ability to multitasking and the movement of the robot is not disturbed by wires. Multichannel transceivers use different frequency channels to transmit data. The command data and monitoring data can be transmitted simultaneously. This multi-channel transceiver has an average pairing time of 23.59 ms, a range of 116 meters in each channel and large power consumption of 59 mA.

Abstract

This research aims to develop an energy capture system, specifically an antenna rectifier. The chosen antenna for this purpose is a microstrip antenna operating at a frequency of 2.4 GHz, utilizing a 2x4 array configuration to enhance the collection of electromagnetic waves emitted by an Access Point. To enhance the rectifier's voltage-doubling capability, the design incorporates three distinct levels: level 8, level 12, and level 14. Experimental results from implementing the 2x4 rectangular H-Slot array microstrip antenna rectifier demonstrate its capacity to convert incoming AC waves from the antenna into DC voltage. During the implementation phase, the rectenna harvesting system exhibits notable outcomes. The most significant outcome is observed in the 14th-level rectifier circuit, yielding a conversion of 101.98 mV when positioned 50 cm away from the wireless source or access point. This voltage reading diminishes to 49.148 mV at 200 cm. In the 12th-level rectifier circuit, the values are 64.8 mV at 50 cm and 39.08 mV at 200 cm. Furthermore, the 8th level circuit generates 24.72 mV at 50 cm and 11.4 mV at 200 cm. Evidently, the proximity of the testing distance correlates with the magnitude of the produced voltage.
