I'm trying to make our arms weigh less than that in their entirety, manipulators included.

you misread- we still have 20-30 lbs to meet limit without the manipulator mechanisms. The bulk of that will be in motors in the lower section no doubt. But this will be a very simple design that will do the job.

The material is aluminum- heavily cheesholed for weight. We are very fortunate to have some great help from our guys at Bristol Myers and they know how to get these things done.

BTW- if you search out our 2000 robot you will see similarities on how this is done. Note the uprights on that machine. Making a tower like this is no secret but making one well is the tough part.
