All my designs & progress available @ Marginally Clever
Update: Apparently this design is also really effective for vector thrust on an RC kite. Who knew?!
They were first researched in 1938. Curtis Boirum built one that got on Hackaday. Now I bring you the plans for a model that you can print and build yourself. Use one to make an awesome RC car. Use two to make an RC car that can move in any direction. I'm using one to make a line-following robot. It has about 15 degrees of movement on either axis.
If you use one of my designs, please let me know! I'd love to see what you make with it and share with others who are interested.
i am still correcting this model, it is missing a few holes. If you can figure out where to drill then add
two hobby servos
one Tamiya 70171 kit (cut to size)
a pair of single-arm servo horns (or amputate a double arm)
3 10mm M3s
a pair of zip ties
- a 5v0.2a DC motor
Assemble as in the pictures. Expect to file a bit because it's a very tight fit.
I haven't found a good way to attach the hemisphere, please comment with your thoughts.
The body of the vehicle will be made from folded cardboard with a pair of free-spinning wheels on the back. I'm using QRD1114 IR sensors for the line detection and an Arduino to do the homework.
