Overview of Design
Lead screw Gripper Design Details:
- Lead Screw = 3/8" diameter, 0.166 lead
- Using two lead screws, one left handed, one right handed
- Lead screws will be driven by one 550 motor with banebots 5:1 transmission
- Actuation speed = 8 in/sec
- Force = 100lbs
4 Options evaluated
Lead screw (Design Chosen)- 1/14/2015
4 Bar linkage-
Scissor Actuator-
Single Cylinder Pneumatics w/ Cable wheel-
Work Accomplished on 1/10/2015
Task list
•clean up calcs and review w/c.s (goal speed (lifter) 1m/s)
•look at 2013- use same lifter opt 1 – scissor lift, opt 2 – 4-bar, opt3- lead screw. Opt 4 – single cyclinder w/ cable wheel
•get lifter group to understand, sude- lift mech
•divvy up components
•pick wikki student
•strategy/control- do we need 2nd grip to go up and down
•size/pick motor (27 stacks) mech cam controls force
•decide on grip design MB. # of open/close – proof pneumatics works
•answer G’ or 5?????-Larry irrelevance
•review parts/ assembly log
•steps- w/static upper
