WEEK 5

Date: 28 February 2020
Place: EE Building, 3th floor/ Room 304, 2P22
Before lab
l We were working on code writing of the
automatic part this week.
l During this weekend, we discussed how to
let the robot react when the recognition system detects the pet. We thought up an
idea to determine the distance between pet and robot. When our pet is close
enough to the robot, the robot will move to the opposite way.
l Team members spent a number of time on
writing the program.
During lab
l Test the manual control function and it
goes well.
l Try to run the automatic part but fail.
Problem and solution
l we met problems
when we try to test the code of auto-control function.
When
we launched the Python interpreter on the command line and then input: import Tensorflow
as TF
It
showed:
ImportError: No module named Tensorflow all the time.
The
reasons may be one of Tensorflow's dependencies is outdated or not installed.
We
went through a lot of information and made a final decision to change a path
and install Python again. We also checked and changed the running python
directory, but it still did not work.
l Besides, the robot didn't
work as expected. When we tried to control the robot though web side, the robot
worked but it cannot go fast. The two motor did not run as expected. At first,
we thought there was a problem on the program, so we changed the control mode
to Bluetooth control but it acts like the same.
Therefore,
there may be problems on hardware. We removed all the extra comportment such as
the servo, the obstacle avoidance module etc. and then it ran faster. However, we
still cannot solve the motor’s out of sync problem.
One team member
thought the robot has insufficient power. Since we cannot provide the raspberry
pi enough power by charge pal, we will try the standard charger next week. Furthermore,
it means the robot maybe can only moves in a certain range.
