Every year, we conduct at least two design reviews at which mentors, advisors and professional engineers gather to provide students with suggestions and point out potential flaws in the design. Here are the things discussed at this year's design review:
CHASSIS
Chassis-long w/concave 8" in to help grab the ball
4-wheel drive w/Andy Mark wheels
Finishing wheel blocks
General layout of the electronics
Battery/spool/compressor to be added later
Switch out gearbox to the toughbox
Probably be 3-4 ft/sec faster than last year
Have the ability to go faster
If not enough space for electronics, maybe make a second story
Concave isn't that wide and probably will be able to handle load if bumped
Bumpers at specified heights
ELEVATOR
ELEVATOR WORKS!
Thinking of using Igus parts but chose to use Bosch
6 in spool
Elevator goes 8 ft
Made decision to go elevator
Consider moment of the ball
Consider friction
GRABBER
Forklift
Added joints
Tested on another robot
Picks up six inches off the ground
Dimensions on prototype not finalized
Goes down on the ball
Two prongs run by one pneumatic piston
Putting foot on claw to push the ball out
Tilted upward 5 degrees
Add torsion springs
Use aluminum tubing for prongs
Prototype can lift the ball!
Possibly add rubber coating
Better mechanical stops
Probably things to fail are the prongs
Use setscrews
Look at thick wall tubing or shafting
Prongs may bend
Concentrate on blocks
Calculate F=ma
Can vary speed going up
Maximum possible speed is 7 ft/sec
Maybe put foam rubber
Weakest point is hinge point
Put hinge on both ends so it doesn't get in the way of anything
ELECTRICAL
New Gyro chip, don't know how to do absolute positioning
Training three freshmen
Remote only works for forty-three feet
Maybe hack into remote and get high powered LED
Have not done anything for elevator control
Try to get people trained to do electrical stuff, making good progress
Maybe do gear tooth counter
Gearbox comes with holes that may fit gear tooth sensors
OVERALL
Know what we are focused on
71 members yay
Heatsinks? Motors overheating
Backdriving
