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/Drive train
Bumpers, how much concave to help get the ball?
Bumpers, how much concave to help get the ball?
Casters
omni
How much advantage of small side?
RC wheels style?
Omni Wheels
good for positioning
costs!!
WILL GO SLOWER
"gain is much less than what you trade off"
Neat maneuverability features
easier to move/turn
SPEED VS. MANUVERABLITY
Gyro
measure rate
rotation rate
catch change in direction
rate integration
differential drive
if robot starts to turn, the gryo can catch it
control loop
zero rotation rate
gear tooth
Arm
1 pivot joint arm
DO THE MATH
can be more reliable than elevator
KEEP 1 pivot
tip catcher on back of chassis
ELEVATOR
how is the elevator going to be drive?
About 7 fps
the overlap...that much necessary?
width of ball
push ball away by accident
Grabber
- can be changed to have 1 actuator to pull the ball up instead of the grabber going down on it
- have the thing swing around so it rolls the ball across
