This is a copy of Peter Jaffe's notes, combining what happened during the day and the design criteria. Tried to keep faithful to the original.
I. Introductory Notes and Administrative Notes
A. SPI Registration Needed
1. Russell is the Materials Head
2. Needed to ship additional pieces
B. Rules Test in Johnson's Room (Tuesday, 6pm)
1. Two updates on the websites
C. Upcoming Schedule
1. Week 1: Brainstorming
2. Week 2: Design (PDR, CDR)
3. Week 3: Build Subsystems
4. Week 4: Build Subsystems
5. Week 5: Integrate
6. Week 6: Test, rebuild, train, prepare for ship, rebuild, test, panic, rebuild
go back to week 2, ship
D. Tripp's Notes
1. People need to show up always and on time (attendance)
2. Dave's [Tripp] handling too many pieces of paper... poor guy
(Things don't go through Tripp!)
3. need people to work on finance and travel: somebody at every meeting,
(see attendance above)
4. Time to TAKE RESPONSIBILITY for logistics and administrative jobs
E. Jacob's Notes
1. Need to take responsibility as students as members of the team:
this is a team of students, not engineers
F. Dave's Notes
1. In response to being behind on the field, we need to stay on schedule and
do what we say we will
G. Parent-Link System for Robotics
1. 810-2296 ex. 2108
2. Used for inclement weather and other random stuff
II. Design Selection
A. Initial Concerns
1. Let go of ownership
2. Be respectful of feelings and do not attack: constructive criticism
B. Design Group 1: G1 (George)
1. Drop down ball grabber-basket
2. Drill motor mobility tank drive
3. Protection wheels on top, back in case of knock-over, weight however on
front, but bar attachment on the top
4. Total height: 35 inches
a) No attempt for bar underpass
b) Moderate center of gravity
5. Fairly wide base
6. Bumpers for shock absorption
7. Aluminum construction for frame
8. Basket holds six balls maximum
9. Wold have few defensive devices for knocking out balls
10. Score: 38
C. Design Group 2: God-Inchworm
1. Angled and flexible base
2. Two baskets with fold-down sides
3. No elevators on hooks--spread out base to get off ramp
4. Normal running mode: 5 feet
5. Possible chain or belt drive
6. Score: 58
D. Design Group 3: Fred
1. Arm on the top of the net, kicks balls around, pushes ball from trough
2. Batteries on first level in the back, control systems on second level
3. Backboard for human player interaction
4. Scissor lift elevator system
5. Spinning end effector ball gathering mechanism
6. Score: 47
E. Group 4/5: Great White Elephant
1. Direct Drive mobility base in U shape
2. Internal-conveyor ball channel with launching capabilities, folds up, holds
a hook and puncher
3. Hook extension attachment capabilities
4. Can acquire balls one at a time at full speed and movement
5. Positive ball control
6. Simplistic: designed under specialized robot philosophy
7. Score: 49
F. Group 6: Cage
1. Sweeper acquires balls
2. Uses full dimensions at start of match
3. Ten or twelve ball maximum
4. Channel starts at four feet, folds down and in two
5. Center wheel drive
6. Score: 49
G. Group 7: The Angry Dwarf
1. Two hooks to grab onto bar, two degrees of motion
2. Tank drive system
3. Bumpers on the sides
4. Screw mechanism for depositing and lifting balls
5. Score: 41
H. Group 8: Jacob's Dolly
1. Scissor lift with lead screw
2. Hook through the chamber
3. Falls down for five foot length
4. Botball-like baoll acquisition system
5. Can get under the bar
6. Score: 59
I. Group 9: Jack's Thing (disregarded for time factors)
1. Four-wheel drive by two drill motors
2. Battery towards front
3. Roller falls forward at beginning of round, drives over balls and
suck them in
4. Actuator Arm
5. Bumpers along entire robot
6. Basket to hold balls, dump truck abilities, basket expands by rotation
of top netting for human interaction
7. Telescoping elevator with ability to manipulate angle by 15 degrees
8. Short enough to go under bar
9. Servos to alter speed of robot
J. Vote between Inchworm or Dolly [done on the next Monday]
1. Inchworm: 0
2. Dolly: approx. 21
3. Winner: Jacob's "Dolly Llama"
III. Subsystem Selections
A. Mobility Base
B. Control System
C. Integration
D. Scissor Lift and Hook
E. Ball Acquistion
F. Basket (Closely Linked to Push-Over System)
G. Pushover System (Closely Linked to Basket System)
