We had much progress in the past two weeks. We are able to control the power of the transmitter through the raspberry pi by using python code. We set up two sets of raspberry pi, relay, and transmitter.
We are also using magnetic sensors to identify when the robot is docked.
The followings are the links to the video demonstration of the successful control of the magnetic sensor by using raspberry pi and relay.
if(gpio.input(hallpin) == False):
print(“magnetic not detected”)
What still needs to be done:
Meeting with Dr. Min:
Our group met with Dr. Min on Monday, November 19th. We updated the progress we made and also talked about our concerns. He provides us with another transmitter that we need for the experiment. We really appreciate Dr. Min’s support and mentoring.
We received the parts we order from Amazon last week. We found out the male ones do not match with the transmitter. Because the transmitter requires a larger jack socket.
We ordered another kind of connectors, and they seem not working either. We will meet with Dr. Min next Monday and figure out the solution.
There are a few assignments that are distributed to three of us:
Python programs that calculate the best route from the starting point to the destination –Daeun
The connection between the raspberry pi and the robot — Yaqin
Identify whether the robot is near certain transmitter — Shulin
We have an ideal map for the initial experiment, which will be conducted at Korean Square. The ideal map shows the path of the robot we are trying to achieve, from Yaqin’s office to the conference room.
