Faith was inspired to create JuJu after interning in at Williamsburg Hospice and Baylor Scott and White in her low income city. One time a patient got into heart attack due to the nurse accidentally injecting the wrong medication into the patient. There have been various more times like this where horrible accidents happened because of wrong time, wrong dosage, or wrong patient.
As for Vivian, her mother recently got diagnosed with Covid-19 and she realized the importance of maintaining human distance and limiting human contact. Her mother and her go to doctor visits and she realizes that lots of low income medical offices lack the resources to thrive during this pandemic.
What it does
The JuJu robot carries pills, medicine, medical equipment, verifies the correct medication input, communicates to a mobile app, maneuvers through environmental obstacles, identifies the correct patient room via RFID technology, and provide security via fingerprint scanning.
How we built it
Although JuJu is not fully finished - about 85% completed. The most important features of JuJu include the fingerprint authentication, mobile app, RFID reader. The fingerprint authentication ensures the security and safety of objects held by JuJu. The mobile app informs the user of alerts, updates, and instructions regarding JuJu. Lastly, the RFID reader includes a unique UID, Room # that is updated with patient information (up to 2KB data) and remotely access information within several cm, unlike QR Code. The Piezo Buzzer beeps when the target RFID is reached. Additionally there will be a weight sensor for medication or medical supplies. The force resistant sensor continually checks for pressure applied to the sensor and it is attached to the container that senses object weight and removal. The Pixy Cam attached to JuJu contains a built-in vision sensor and object tracker. The camera will confirm the quality and quantity of the object before delivery. The camera will be in the base station of JuJu and will be connected to a USB on the computer. To ensure that JuJu does not collide with any objects or individuals within the medical environment, we have considered route optimization. This keeps the robot moving along the right wall, if there is a right, then turn right, if not, the robot goes straight, and if both right walls and front walls exist, then turn left. This algorithm allows JuJu to patrol the perimeter of most medical floor layouts. In addition, by using left and right ultrasonic sensors, we can measure the difference in distance from the wall to further guide JuJu’s path. We can control and adjust the left or right motor speed using Pulse Width Modulation (PWM). These two factors ensure that JuJu is able to automatically calibrate, running in a straight line without use of a coordinate system, gps, or controller, keeping a consistent distance.
Challenges we ran into
We ran into various challenges from researching and analyzing clinic studies to utilizing time management to complete as much of the robot as we could. We also had to work with our different time zones and schedules to meet the proper hackathon deadlines.
Accomplishments that we're proud of
We are proud of our late night work sessions to complete building JuJu (finishing the sensors in tandem) and the mobile app. We are also proud of our resources and flexibility to reach out to professor and medical professionals we knew.
What we learned
We learned a lot about team work, the effect of socio-economic disparities in the health care, time management, and also how to effectively complete projects.
What's next for JuJu
There are various next steps including finishing our mobile app, finishing JuJu and getting it patented, contacting various medical institutions and professionals, deciding between nonprofit or business, and building our brand and social media strategies.
