Greetings!

If any of the info on this website was useful for your projects or made your head spin with creative ideas, and you would like to share a token of your appreciation- a donation would be massively appreciated!

Your donation will go to my Robotics Fund, straight towards more sensors, actuators, books, and journeys. It takes a lot to continue building these robots, and I’m really thankful of everyone who helps encourage me along the way.

R.I.P. Workshop – Final Day

Today was the final day of building everything before all of our supplies and junk goes away. I can’t believe it is almost the end, and the robot has become very built over the past few days, but it still is not exactly how I want it.

I started off by doing some wiring! Found some yellow LEDs for the eyes, and Niklas is lending me his IR sensor!

Here is how the robot face looks with the LEDs and sensor on it. Its antennas are ends of serial cables!

The LEDs are mounted through the back of the face plate:

Sometime before making the arms, I sent a tweet out for name suggestions. @Kiteaton had a wonderful suggestion- “SCRUMBLEFLIT”, and it just sounds so perfect for this robot. It sounds like “what on earth is going on!” in robot language.

Here are the arms mounted on the stepper motors thanks to much hot glue!

The hand is made out of copper wire, with lots of solder, and the keys say “ROBOT”!

Inside of this can there are screws, to try to make noise. I chose Orange C plus for this because it is tasty and sounds like the programming language, C++.

Took some time to visit the place where I will be showing off SCRUMBLEFLIT, the town hall! It is a pretty decent town hall!

Afterwards I went back and worked with the LEDs for a bit. They are interesting because they cast light along the edge of the circle in the doorknob.

I created a blink that seems believable. I do it by quickly (but not too quickly) fading the LEDs to a low light, to signify the eyelid closing, then it jumps back to bright light, to signify the eye open. Blinking on robots is tricky, because if you don’t do it properly, it looks like as if it is glitching out.

After this, I was working on the arms again. Everything was going fine, the arms were moving, then everything stopped. The power supply wasn’t on anymore. As Niklas later taught me, what might have happened is an exposed wire might have touched the outside casing of the supply, making it go into shutdown mode. Apparently power supplies are really dangerous and can explode a lot. Hopefully it doesn’t make SCRUMBLEFLIT explode!

Anyway, I sort of got it working again a little while later, but the problem now is that it takes ages for the stepper motors to “warm up”. What happens is that everything is plugged in and working, but the steppers aren’t moving. However, if I take the power out of the steppers and plug it back in, you can hear and see it react to the voltage, but it doesn’t keep moving. This has happened before in the previous days, still unsure about what is causing it though. It usually goes away by itself, but when it doesn’t, it is really annoying.

We will see what happens tomorrow. I have to wake up early and move my robot from one place to another since it is in the studio right now, so hopefully it isn’t raining then! Tomorrow will have a lot of explaining about what the robot COULD have done and what it SHOULD do. I enjoy talking about robotics nevertheless though. :)

Everyone’s projects are absolutely stunning! We created so much in a short amount of time, with unplanned materials. Creativity has some amazing super powers!

Here is a video of the robot’s eyes blinking!

    Creating such kind of stuffs are really awesome work. They are a piece of art, as well as technology. But, don’t you think that, creativity would have been a bliss if it’s used for the upliftment of mankind? Like developing more advanced robots that can do various things to help mankind and take them on a journey of success & prosperity.
