Week Nineteen

Project Development

What is the deadline? How much time do I have left?

The dead line is 19th of June, that gives me 11 days to finish my project.

what tasks have been completed, and what tasks remain?

Till now I have made the prototype of the body, milled and stuffed all the main control boards, tested the electronics and made sure they were working, assembled all the electronics into the body and still experimenting with tuning the PID constants. I have gone through many tutorials on how to tune the PID constants but have still not achieved a proper result.

The tasks remaining are the making the final body, making a cover for the robot body, Designing and 3D printing a support for the MPU6050 sensor.

How will I complete the remaining tasks in time?

I have very limited time left and a lot of work still left to do. I spend a lot of time tuning the PID constants.

I stopped my tuning efforts and began prioritizing the work I still have to do. I set deadlines for individual tasks and will finish them within that time slot.

For now the important thing is making the final body, assembling all the electronics into the body and getting all the electronics to work together, then I can focus on the code.

What has worked?

•The body is fine and works well.
• The sensor is calibrated and working fine
• The code works and the bot responds to changes in angle.

What hasn't?

• My main controller board is giving me issues
• Still can't get the board to talk to the sensor
• Serial communication is not working

What questions still need to be resolved?

• Why is my Main controller board not working properly
• Is there anything I missed in my PID tuning efforts
• Is the weight distribution proper in the robot body

What have you learned?

• How to design, with the end goal in mind.
• Almost all the fault in electronics can be traced to improper connections, checking continuity will save a lot of time.
• Always test your designs before making the actual thing.
• How to tune a PID controller
• Header pin joints and jumper cables connections are unreliable, solder joints if you want reliable results.
• Things don't work out the way you imagined it will

I have documented in detail the problems I faced and the trouble shooting I did in my Final Project page
