For many of us, movies are a great source of inspiration for projects, and the Star Wars films are a gift that just keeps giving. The D-O droid featured and the Rise of Skywalker is the equivalent of an abandoned puppy, and with the help of 3D printing, [Matt Denton] has brought it to life. (Video, embedded below.)
D-O is effectively a two-wheeled self-balancing robot, with two thin drive wheels on the outer edges of the main body. A wide flexible tire covers the space between the two wheels, where the electronics are housed, without actually forming part of the drive mechanism. The main drive motors are a pair of geared DC motors with encoders to allow closed-loop control down to very slow speeds. The brains of the operation is an Arduino MKR-W1010 GET on a stack that consists of a motor driver, shield, IMU shields, and prototyping shield. [Matt] did discover a design error on the motor driver board, which caused the main power switching MOSFET to burst into flames from excessive gate voltage. Fortunately he was able to work around this by simply removing the blown MOSFET and bridging the connection with a wire.
The head-on D-O is very expressive and [Matt] used four servos to control its motion, with another three to animate the three antennas on the back of its head. Getting all the mechanics to move smoothly without any slop took a few iterations to get right, and the end result looks and moves very well.
[Matt] worked on the film himself, so he based his build on a design by [Michael Baddeley], another prolific droid builder, to avoid breaching his NDA. He covers the entire development and testing process in a series of videos, and will be releasing the design files and instructions when it’s done.
Respect for the project, although, this droid is the most useless droid in the history of movies. Just my 2 cent…
After seeing this article, I mentioned D-O to my daughter, she had seen the movie, I haven’t.
She had no memory of D-O being in the movie…
She said she lost interest while the movie was running.
Wow!
About as far as building my own,
I could probably find a hair dryer that I could use for the nose.
Please host your projects on smaller privacy problems than FB…
…or how much does the Zuck pay you for tempting us?
I get Hackaday notifications from an RSS app called Feedly. No ads and AFAIK no Zuck.
This D-O project seems to be hosted on Facebook – I think Feinfingers’ appeal was to Matt Denton, not HaD.
Matt has a Youtube account he posts on (winchymatt) insta, twitter (mantisrobot) and has a career in building stuff in general http://www.micromagicsystems.com/ other projects include mantis robot, IC hexapod, his early projects got me interested in making stuff!
Very impressive!
Although i dare say the mighty MrBaddeley, deserves a lot of recognition for this droid, and many others, especially in terms of bringing star wars designs to life, for us mere padwans to create on our 3d printers
