What we have done!

Here is a concise list to show what we have done for this project.

1. Reverse engineer all of the robot’s electronics so that we understand what the past group did.

2. Fix the broken motor control board, power up the robot and use the handle to make it move, proving that the basic functions of the robot are perfect.

3. Make a stable platform inside the robot, which has three layers. Batteries are on the first layer, control parts such as Arduino and Raspberry PI and most of the wires are on the second layer, the handle and the converter box is on the top layer.

4. Build a converter box which can be a 5V and 12V power supply. And there are two interfaces and one switch on the box.

5. Power up the Arduino and Raspberry PI using the battery and convertors we built inside.

6. Test the camera and test a simple program to recognize numbers.

7. Connect the sonar to the power supply and power it up.

8. Assemble a strong and professional robot arm.

9. Build a platform outside the robot to help the robot arm touch the button in elevators.

10. Design a matlab function to calculate the degree and path of the robot arm. This will be used by the robot in the future to determine the orientation required to press a button or lift an object.

11. Attach the robot arm to the platform stably.

12. Connect all parts of the robot together and test it.
