9 days left to my viva… and my boy is still not “standing still”… Nah, don’t think “dirty” things ok…
For those who don’t know what bothers me most for the past whole year and those who are not sure of what I’m crapping here , it’s my final year project… A two wheeled self balancing robot… Lots of trial and error involved and lots of frustration. Modification after modification, and now it’s finalized.
My very first version that didn’t work at all:

Weight: about 4 kg something (not including circuits and drivers)
Height: 0.7 meter
Reason of failure: The motors are too heavy, resulting low center of gravity.
The second version that’s unstable:

Weight: 2 kg
Height: 0.55 meter
Reason of failure: Frankly, I also don’t know what’s the reason… it balanced at one spot, then started swaying bigger and bigger, then fell. Maybe the algorithm was not right or suitable.
…And now, the third and final version.

Weight: 1.8 kg
Height: 0.36 meter
Deliverable: Uncertain, still in the process of tuning.
Gonna rush for the next few days… Hopefully everything goes well.
