Scissor Lift Preparation?


#1

Our scissor lift is not very fast, since it uses 4 torque motors on a 3 scissor lift with a chain bar on top. We don’t have the time to redesign our lift to a double-reverse four bar, so what should we do? States start March 3rd and our next competition is February 17th, though we are already qualified.


#2

Try high speed. Four motors should be more than enough.


#3

Thanks for the idea. We will try that.


#4

Build a DR4B separate from the bot while your driver gets practice and then attach it when it’s done.


#5

Our problem is that we only get 5 hours a week, 2.5 Tuesday and Thursday, so we don’t necessarily have the time to build one separate.


#6

Take the parts home.


#7

If taking parts home isn’t possible using CAD to plan your robot in exact detail would significantly reduce rebuild time.


#8

Our team has never used a CAD program before, so we have no clue on how to properly install or use it. Maybe you could help me with that?


#9

Search for autodesk inventor then download the student (free) version. Then there are many parts libraries available for all the vex parts. For those, search for “vex kop” or something


#10

Thanks for the idea! I will try it once we get home from building.
