Being normal is never enough…

The one year duration is coming to an end, but thinking back since I first started, I’ve been kept on down grading my scope of work. I’ve always wanted to learn and try more, but somehow my “demotivating and lazy” side always prevails. One year ago, the initial plan was something like this:

Ballbot

OK you might start scratching your head now… what the hell is this? Well, it is a single wheel balancing robot. When I say SINGLE WHEEL, the wheel is actually just a red rubber ball, and the robot is balancing on top of it, without dropping of course. Cool huh?

But now all I did is just an ordinary two wheeled balancing robot. You might ask what’s so different between this and mine? Well…


1) Mine doesn’t have wireless remote control to make it move around.

2) Mine got no Graphical User Interface (GUI) to analyze the robot performance and system parameters.

3) Mine got no sensor to detect obstacles.

4) Mine is done by much trial and error, which spent me most of the time doing unnecessary testing and reconstruction.

5) Mine is still not balancing perfectly.

6) And most importantly, mine got an extra wheel… which makes the whole thing from cool become totally UNCOOL.


Tomorrow will be the “judgment day”. There is nothing much I can do right now in less than 24 hours. I am prepared to accept any harsh comments from the panels.

Wish me luck…

People says,”It is always darkest before dawn”… It is really true?

Because for the last whole weekend, I have been getting all the unexpected shits… and lost almost half of everything.

One week left, can I make it in time?

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:

1st_version

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:

2nd_version

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.

3rd_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.

I can’t believe it…

I really can’t believe it…

That I’m being so reckless…

That at this critical moment, I decided to make this major change to my project’s whole mechanism.

Intuition? I doubt it…

And yet I really did, rushed and completed in one day.

Hope this time it can really works…
