Hello, my name is Carlos Orozco, and I am a  High School student. My partner and I competed at the Greater San Diego Science Fair this March obtaining a 3rd place, we developed a robot that can assist senior citizens and/or medicine users in a way that the administration of their medicine can be controlled by an autonomous robot. 

To build this robot we used an Arduino UNO. We connected a GPS Shield on top of the Arduino UNO an then we connected it to a Rover 5 Motor Driver. We used 4 gear motors and we connected them to the Rover 5 Motor Driver. Then we connected the Rover 5 Motor Driver to the GPS Shield and then we programmed a course that the robot is supposed to follow to deliver the medicine. 

We had a lot of trouble with the programming part, if somebody would be willing to help us it would be amazing. The basic goal is to create a GPS coordinates
 path to deliver medicine to the user. Some example codes will be above of this blog.

This is the total list of parts we used:

Chassis

Wheels

Arduino UNO

GPS

Rover 5 Motor Driver

4 GearMotors

12v Battery (For the gearmotors)

9v Battery (For the Arduino UNO)

Hello, my name is Carlos Orozco, and I am a  High School student. My partner and I will be competing at the Greater San Diego Science Fair this March, and we are trying to develop a robot that can assist senior citizens and/or medicine users in a way that the administration of their medicine can be controlled by an autonomous robot. The robot is not finish yet, and I am asking for any type of technical help.

The first idea of creating the robot was of using a Raspberry Pi to control and Arduino UNO. The Arduino UNO is in charge of moving the motors so the robot can move around the house, we also tried to connect a Web Cam to the Raspberry Pi so with a Computer Vision Program the Raspberry Pi would be able to identify the medicine user. None of these ideas have worked so far. I am trying to buy an ArduPilot, but I am not very sure if that is why my robot need. 

I am still trying to figure out the mechanism to deliver the medicine at fixed hours.

This is the list of parts we have so far:

Chassis

Wheels

Web Cam

Arduino UNO

Arduno MotorShield

3 GearMotors

Raspberry Pi

*I spent all my Christmas money in this robot, any donation or technical support will be appreciated. 

*Special thanks to SparkFun Electronics for sponsoring us with the aluminum bars and the wheels.
