Family Day

Tuesday is the day the lead coach spends with his family, so the following note was left for the team members:

LIFT ASSEMBLY

Design and CAD the lift – determine what & how many materials, hardware, fasteners, connectors are needed.  Determine the weight of the structure, precisely how it will raise & lower, how the end effector will articulate, how the motors will be mounted, and how the lift will mount to the drivebase.  Work with the Controls team to determine what sensors are necessary and where they should be placed.  Create a Bill of Materials that outlines what parts need to be ordered/manufactured to create a complete assembly.

Knowns: 

•Each vertical section of the lift is 48”.

•The horizontal distance between the innermost sections is 5”, ±0.5”

•The material to be used is 1010 T-slotted profile.

•When the lift is collapsed, the tip of the end effector needs to be just below the feeding slot.

•When fully expanded, the horizontal part of the end effector needs to be at least 115” from floor level.

•It has been suggested that the members of the lift be connected by rollers (check out first mast model.pdf in this folder).

•Each section’s components must be connected.

•The system must be statically and securely mounted to the chassis.

•The end effector will be powered by a Denso motor; the lift will be powered by a Fisher-Price motor.

•All 8020 components may be found on the website, www.8020.net.

FLOOR LOADER

Design and CAD the floor loader – determine what & how many materials, hardware, fasteners, connectors are needed.  Determine the weight of the structure, precisely how it will “unfold” and grasp the game pieces and place them on the end effector, how the motors will be mounted, and how the mechanisms will mount to the drivebase.  Work with the Controls team to determine what sensors are necessary and where they should be placed.  Create a Bill of Materials that outlines what parts need to be ordered/manufactured to create a complete assembly.

MINIBOT

Design and CAD the minibot and deployment system – determine what & how many materials, hardware, fasteners, connectors are needed.  Determine the weight of the assembled structure, how the mechanism swings out and engages the post, how the motors and actuators are mounted, and how the mechanism will mount to the drivebase.  Work with the Controls team to determine what sensors are needed and where they should be placed.  Create a Bill of Materials that outlines what parts need to be ordered/manufactured to create a complete assembly.

CHASSIS

Work with the Floor Loader, Minibot, and Lift teams to make sure there are areas to mount the systems and enough space to fit everything together.  Work with the Controls team to make sure all the electrical components are secured and placed correctly.  Design and manufacture bumper mounts.

CONTROLS

Work with the Floor Loader, Minibot, Lift, and Chassis teams to make sure there are correct numbers and proper placements of jaguars, victors, spikes, and pneumatic components.  Make sure the parts are correctly placed and secured, and that the wiring is correct, organized, and complete.  Mount and wire the necessary sensors, both for the subsystems and for line-tracking/field element targeting. 

CAD

Work with each subteam to ensure all components are properly designed and, if necessary, ready for fabrication.  Complete the field.

AWARDS

Continue work on all awards as well as marketing and outreach programs.

This morning when the lead coach came in the workshop, there were a lot of clean tables, rearranged field carpet, swept floor, and clearly labeled drawers.  The mecanum wheels for the practice bot were assembled (since we don’t have another set of hubs, we’re doing chain-and-sprocket at a 1:1 ratio from ToughBoxes). 

Perhaps the lead coach should be gone more often …

The 8020 guy is scheduled to drop by this evening; it’ll be exciting to finalize our lift design and get the parts ordered. 

Our McMaster-Carr order ought to be delivered today – aluminum tubing, bushings, and a tube bender.  We can make our floor loaders.  Allison Babcock will be proud.
