Here is a little something I have tried to save my chains from breaking. On my Stack-It-Ball bot (see Other Contests), I use a rolling Pringles can to “capture” racquetballs. Sometimes, things jam up a bit and stop the Pringles can roller. When it stops, the motor breaks the chain.
My cheesy solution? I dismantled the motor clutch and with a Dremel grinding/cutting disk, cut of a chunk off the spring. After several tries, I now have a motor clutch that readily “pops” under moderate torques and saves the chain from breaking. This was a very quick fix since changing sproket sizes and motor speed would take too long.
Anyway, it was a noteworthy experiment, and may prove quite useful for sensitive torque applications.
One note is that the clutch design doesn’t lend itself well to light torque applications. The slip plates (and spring) appear to have been designed for 10 pound inches or so. Getting down to 2 or 3 pound inches took me a couple of tries. The spring now barely pushes on the slip plates. The consistency of when the clutch slips leaves something to be desired.
they wont chang the color from green, if you hadn’t noticed the parts are color courdinated. green is motion, blue is power, red is sensors, yellow is transmitter, orange is programming, and gray is struncture. so by looking at just the color of a part you know what it does.
