I designed this yesterday. I think it would be great to use a reverse double 4 bar for the Next Level Challenge. This one works, but it is very unstable. I’ll go back to the drawing board today. Hopefully I’ll have a functional prototype before the end of the weekend.
In the meantime… Check this out:
If you listen closely, you can hear the gears slipping when it reaches the top. That is because of flex in the system. Also notice that it moves way too fast. I could reduce motor speed though, but I would lose some torque as well.
