Former NASA and Apple engineer. Current ISdownsr and friend of science.

Answers to some common questions:

1) I studied Mechanical Engineering in School. I did my undergrad at BYU and Masters at USC.
2) I worked for NASA JPL for 9 years, 7 of which were working on the Curiosity Rover (I made a video about it you should def totes watch cause it's probably my favorite of all my videos). Then I created Digital Dudz (made some videos about this too) and eventually sold it after 2 years. Then I worked for Apple in their Special Projects Group doing Product Design as a Mechanical Engineer for 5 years. As of 2019, I just make my monthly ISdowns videos.
3) Link to free and therefore substandard build plans for my custom workbench can be found below.
4) I made a 30 Day Creative Engineering Class that teaches my end to end engineering process so you can make stuff too! Check it out here-

    It doesn't matter how interested I am in the content, when I have to struggle to stay focused on the narration because obnoxious background music is driving me crazy, the video becomes a fail for me.

    The obvious shortcoming of this design is that you can't start it from a single point of origin, which is one of the main things that makes dominoes so fun. This also shows up in the video, before your edit you can clearly see there are columns which weren't triggered. So I appreciate your efforts, and also appreciate that even this version of the robot is a lot of work, but it feels like you ended the iteration process early because you needed to release a video.

    If they make a robot that cleans stuff up, they should take inspiration from the office, and create “Suck it”

  • City

    If you made the loading system mobile and had 2 movable loading robots you could have 1 loading up on dominos and the other follow dom around giving dom a constant supply of dominos making it much faster.

    @Mark Rober What let you chose to only make one „magizine“? I would say that you can make it even faster when you copy and paste like 3 more magizines ok top of the one so the robot can drop the first one, close it and open the second one letting the dominos dripping down in the first and closing it again. At the same time the robot could move tobte next feld and drop it und so on. The time it needs to drive and relief should be become shorter and so faster.
