I am trying to find online a sample of a forklift with continuous chain drive to show the kids. I have been googling like crazy with no luck. Does anyone out there have a website that I could look at to help the kids? thanks:)
More pictures of that robot can be found here. Unfortunately, not many of them have good view of the lift. I could draw up a diagram for you if you want.

I found it to be very helpful learning how these worked. Also this post has most of to all the answers to your questions most likely if you take the time to read the thread: https://vexforum.com/t/team-1103-robot/18347/1&highlight=1103
