Hand tools and fabrication machines
Once upon a time, in a galaxy FAR, FAR AWAY, I decided to make a space companion bot. This project was inspired of course by Alex Glow and Sophy Wong at Maker Faire Bay Area 2019. I was inspired by the idea of more companion bots and seeing Sophy's talk about her amazing space suit made me excited to try and make a space theme bot.
Well step number one is to print the parts. There are a few parts to make Sun, around 7 inches tall. I tried to edit them the best I could to make them easily to reproduce.
I started with the base.
The ideas was simple. I was gonna make the a skeleton with 3D-printed parts, and cover it in fabric for the space look. After making the base, I went on and printed the Sun's head, which I tried to make a space helmet to be the head.
It fit on top pretty well, but I did hot glue it on to make it more stable. Next, knowing I wanted to use an LED matrix for eyes, I made an LED matrix eye holder with a servo placement holder so the eyes could look back and forth. I also printed a plate to fit inside the head and used screws to attached a servo arm to the plate.
It worked well!
Next, I took a moment to focus on the head a bit more. I used an old acrylic transparent sphere I had from Christmas and cut it in half until it looked like a visor. Then I used a technique I learned from Estefannie Explains It All to tint the clear acrylic, and for an added touch, I cut up and glued some foam to the bottom of the visor.
My next step was the legs. I CADed up some space boots and made a special holder for the servos so the legs can kick back and forth.I then hot glued the servo holders to the base that sticks out. I updated the file I am sharing with you so it should be a bit easier for you then it was for me.
Next was the circuit. It is a simple circuit, which uses an Adafruit Trinket Pro 5V to move three servos at random. I used an Arduino Nano as well for the eyes. At first I had a HUGE problem making them both work at the same time on a single power source, but once I made the circuit be powered by two different lithium-ion batteries, the problem solved itself.
I wired it all together perma board it and made a switch for it. I then used some fabric to cover the body best I could, I admit I am not must of a fabric user so it came out a bit weird but I think it was OK for my first go.
Next, I stuffed the circuit into the body.
I wired it with a switch so on and off will be easily done.
Lastly, I added a GoPro seat for him so he could sit on my shoulder using my bag. I always use a GoPro design for my bots recently, hahaha.
And that is it! I hope this tutorial made you smile a bit or inspired you to give it a try. I am linking all the people who help inspire this little guy below. Have an outer world day!
