I took some advice from one of my other posts, and because I had robotics today I decided to cook up a little something something for ya. I call it the Armadillo Linkage. It’s my own special take on the mogo intake.
Here’s the YouTube link:
I utilized two high torque motors and some gears.
I decided not to go mainstream and instead decided to use a mechanism that I saw a long time ago in the original Vex Robotics Manual.
Just wondering what you all think. It’s obviously a prototype, the gripping part still needs a bit of work in order to grip the goals better. However, it is competition ready–despite how it appears, the robot does fit within 18in when in the starting position.
For the purposes of analyzing torque and speed this is a four bar linkage. Two bars are obvious, the lift bar and the chassis on which the gears are mounted. The two gears are the remaining bars.
If you would like more info on things similar, some are called ferris wheel or choo choo lifts. They are popular in vex and in FRC and a few others so you may get an idea outside of vex.
What’s the big deal if he makes up a name for something. Just call it whatever the crap you want and he’ll call it whatever the crap he wants. If it bothers you that much than just leave the vex forums and stop making such a big deal about this.
Although the idea is similar in that there is a small gear driving a big gear, I don’t really see how it’s the same. Unless you didn’t realize that the camera is sideways, even the direction of movement is different.
The person’s intake uses a similar concept in that the movement of the lift is dictated by the diameter and movement of the larger gear. My intake utilizes two gears moving in tandem to move the mogo grabber into position.
Also, just to clarify for all those reading through this reply, as I stated in the og post, I got the idea for the Armadillo Linkage from the original Vex Manuals. I only took a simple mechanism and modified it so that it could pick up the mogos.
Finally, shoutout to the creator of that FERRIS WHEEL INTAKE. That’s a unique design that I have yet to see anybody using.
I look forward to hearing more from the community.
Just to clarify, your lift is a choo choo or a ferris wheel lift due to the gear diameter changing the lifting arc. That is why it is called the wherris wheel lift due to that fact. Yours is just modified, but it is still the same system. Instead of one pivot, you created two. I feel that that isn’t enough to merit a new name for the community, but by all means you can use it for yourself. I simply ask that you try to find out common names for things that are similar, and try to determine if the modifications you make are enough to merit a new subclass/ name.
