Design Brainstorming<\/h1>\n\n\n\n

This is the draft for the Unitree network configuration for wireless image transmission. The UDP package flows to switch, then Raspberry Pi, and finally the desktop. <\/p>\n\n\n

Power Distribution Board: Add-on Gas Detection <\/h1>\n\n\n\n

Per PCB design, we developed a breakout board to power a gas detector, LED lights, and a buzzer to serve as a warning device if dangerous gas is detected above a safe threshold. The schematic is shown in Figure XXX below. This Arduino Nano will be powered by the robot payload\u2019s USB port (usage) or by a laptop (demo) via a 5V USB-to-micro-USB cable. The Arduino board will serve as the processing unit to operate the MQ-135 gas detector, as well as buzzers for sound alarms and LEDs for visual warnings.<\/p>\n\n\n\n
