Purdue [CNIT 581-SDR/ Spring 2021] Face Mask Detection Robot

For hardware construction: A simple camera holder was built to mount the camera with tripod. For software construction: In these two weeks, we tried to embed the Roomba driving control and python audio into our detector code. Because of the port issue, we were not able to connect the Roomba to our original Linux VW. Therefore, we switched to other computers and platforms. The following are the platforms/computers that we tried and the reason why they were not able to complete our project goals. There are three major functions we are looking at:  1. Can it run the mask detecor.py? 2. Can it install/support PyAudio? 3. Can it access Roomba's USB port and control the robot? Table 1 . System configuration and issues Platform Name What it supports What it does not support Why? VMWare Linux VM Mask detector, PyAudio Roomba driving control USB port could not be opened Raspberry Pi Roomba driving control PyAudio, Mask detector "Arm-linux-gnueabihf-gcc" failed with exit status 1;

  What we finished in these two weeks: Hardware for the robots We have used a tripod to hold the mobile camera. Figure 1&2 demonstrate the graphic design of the robot and how it actually looks like. A 10 ft extension USB cable will be used to connect the camera and the computer We estimated the observation distance between the robot and passengers. Between 1.3 meters to 1.5 meters, the robot is able to observe two passengers at once.

L ITERATURE R EVIEW A. The Importance of Mask during COVID-19 In order to slow the spread of COVID-19, limiting physical distancing and using other measurements to decrease the transmission probability are necessary. According to J. Howard et al., if face masks were used by all household members prior to symptoms occurring, it has a 79% effective rate in preventing transmission. Besides, the states with mask mandates to require residents to wear a mask have a lower daily growth rate than those without. As a mask provides a physical barrier that reduces the spread of respiratory droplets and particles into the air, properly wearing a mask can protect the safety of everyone [1].

The Implementation of Mask Detection Robot Currently, mask and temperature detection robots have shown their important role in responding to the COVID-19 pandemic. The U

  Project Introduction      In December 2019, the first case of COVID-19 was discovered in Wuhan, China. As of March 11, 118M cases were reported worldwide. In order to help slow the spread of coronavirus, CDC recommends people wear masks in public settings. Starting from February 2, 2021, face masks are required in all forms of public transportation traveling , such as bus, train, and plane. To protect the safety of passengers, in this project, we plan to build a service robot that is able to check the mask-wearing in a public transportation scenario. The robot will act as a security patrol robot and identify the passenger without a face mask immediately.  Photo: JEENAH MOON/BLOOMBERG NEWS Project Objectives The robot is able to scan passengers The robot is able to detect if passengers wear facemasks or not The robot is able to move towards the passengers without masks The robot is able to check passenger's temperature The Robot Flowchart Project Plan Week 7~8: Literature review o
