|
|
Goal is to build a 'cool' m&m sorter/counter. Size requirements budget requiremets... etc etc etc
Today's task: mechanical prototype. No motors or anything no sensors and with cheap material.
It will have a color sensor, 2 motors (disk and tube) and 1 PIC controller. Also will be modified to do parallel sorting.
Took 2 hrs to design and build, enjoy

Ya seen that one. It's a very nice design actually single motor but requires some fairly precise manufacturing. Also the main problem with that one is that it requires m&M's to be loaded in a tube. Believe it or not... that's very difficult to do. To go from a bin of MM to a tube of MM in right position. Our's will be a bitmore robust, faster, and also work in parallel (some of the components will be duplicated so the servos can do 4 or more m&M at one time. _________________ "My Heart Is In the Work" - Andrew Carnegie |

Couldn't the alternate be easily modified to no require the tube? To view and examine each one upon it's departure from the dispensing unit?
Both ideas are interesting but I can't help but try to figure out if your design could be done with a single motor. Just seems like there must be a way to simplify the process somehow... |

It could be modified yes.
A balanced walker can be made with a single motor actuation, why make Asimo's complex legs and walking algorithms?
Single motor actuation for this is not hard. The second one IS single motor actuated (if I remember correctly). _________________ "My Heart Is In the Work" - Andrew Carnegie |
