Medicine Delivery Robot

The concept of a medicine-delivering robot stems from the need to enhance efficiency and safety in healthcare settings. With the advent of advanced robotics and automation, these robots can significantly reduce the workload on healthcare professionals, minimize human-to-human contact, and ensure timely delivery of medications. This is particularly crucial in environments burdened by infectious diseases, such as during the COVID-19 pandemic, where reducing direct contact can help prevent the spread of illness. Because of this our group decided to construct a robot that would find and deliver medications to patients in a hospital. Below we describe the steps, coding, and supplies needed for constructing this robot!

Hello! These are the supplies needed to create this robot.

1. Breadboard 
2. Arduino Uno 
3. 2x Gear motors 
4. Gear bridge 
5. Servo motor 
6. Ultrasonic Distance sensor 
7. Photocell 
8. 10K OHM resistor
9. Wires 
10. Cardboard 
11. Duct tape 
12. Power Bank 
13. K'Nex or substitute building material 
14. zip ties

Here we have included the code we used as well as the corresponding flowchart.

This is the circuit we used to code our robot and also what we used to build the physical circuit.

Using the Circuit Diagram from Tinkercad, we built the circuit using the Arduino parts listed above. When constructing this circuit, ensure each sensor and motor is wired correctly by double checking everything. If at all possible, check each wire you use to make sure it works before implementing it into the project.

Using K'Nex pieces and the pictures, construct a shell that has space for the Arduino board as well as the wiring above it. Also make sure you securely attach the gear motors to the wheels and to the Chassis with zip ties. Make sure to also construct a spot on top of the chassis to put the battery pack.

Cut out carboard pieces dimensioned above, then connect the pieces together with tape as shown above.

Take all three pieces that you have constructed and put them together.

1. Place the wired Arduino board into the chassis, make sure it is secured.
2. Wrap the cardboard net around the chassis, adhering it to the connection points.
