17. Machine design¶
This week assignment - actuate and automate your machine - document the group project and your individual contribution
My Contribution¶
- Turntable design & fabrication
- Demo video making
Make a turntable¶
For this week we decided to create a robot hand and I was in charge of creating the basement part which is a turntable.
A turntble is for moving robot arm horizontally which is moved stepping motor & timing belt. This is controlled by Arduino.
On week 15 I designed basement to cut the part by a laser cutter and this week we got the parts so we assembled to make it movable.
First, I put 5 gears together since we need the height to adjust the heights 2 stepping motor. so we decided to assemble it with glue. so before make it production we tested several types of glues. one is 10 seconds and the other one is in 2 minutes. so we use a small part small part of acryl part with 10-second glue and it seems like too fast to getting together because we need to adjust the gears accurately so then I tested 2 minutes-glue.
how many school is also checking because after touching to part it moves easily so I have to be cautious I decided to use 2 minutes glue for gears. So finally we move to actual production of gears and I put it on gears and assemble it.
the tricky part was that years on not 100% straight so some gears tilt a little bit. so I carefully assembled 5 gears and also basement and And the spindle part.
after implement these part I tested if it turns easily and actually didn’t because I put it’s a little bit too far from stepping motor because I intended because timing belt to stepping motor side as I said it was too far and the some parts of it hit the hole so I need to use sandpaper to create this.
after. It turns free functionally so so I moved to setting timing belt with the gears and the stepping motors.
firstly I cut the timing belt for this machine and Tie The End by plastic belt. but plastic belt was gradually loosen cuz of the gear movement so you know the two getting together tightly I made a hole on timing belt and put it together with screw.
it worked out so I got now turntable movement function. and then I put the top part of the turntable with glue again. after that I combined arm part with the turntable by 4 screw. finally we made a robot arm.
Demo video¶
Made a demo video with iMovie and ffmpeg.
First, put a movie into iMovie.
Then, added title effect and edit text.
After that, added endroll with the credit with sound named news from library.
And added hero shots.
This is the finish of editting. So I selected export to make mpeg 4.
ffmpeg¶
In order to compress the movie I made on iMovie, I use ffmpeg.
First intstall ffmpeg on Terminal with Homebrew.
brew install ffmpeg
This time, format was fixed to max 1min, mp4, 1920:1080, under 10MB. So I run a following code on Terminal
ffmpeg \ -i fabmovie.mp4 \ -vf "scale=1920:1080" \ -c:v mpeg4 \ -q:v 16 \ outputMovie.mp4
-i means original file name -vf means size -c means file format -q means compress level
but this didn’t work because file size was still 96.4MB.
so then I tried this.
ffmpeg -i fabmovie3.mp4 -vf "scale=1920:1080,pad=1920:1080:0:0:black" -c:v mpeg4 -q:v 256 outputMovie.mp4
But still 14MB. So I tried to reduce the size of original file. I choose lowest quality when I exported on iMovie, then hit this.
ffmpeg -i fabmovie2.mp4 -vf "scale=1920:1080,pad=1920:1080:0:0:black" -crf 32 outputMovie.mp4 -vcodec h264
