mechanical mechanisms
cams and followers
converts rotational motion to linear motion
straight line movement
many shapes
shapes determines movement of follower
follower shape determines accuracy
speakers
piezo
ideal for single tones
micro speaker
plays tunes
buzzer
one sound
motors
gearbox
set speed
inline
ideal for weels
rotates 360 degrees
cheap
ratio 120:1
servo
high torque
rotates through 180
stepper
expensive
used in cnc
3v motor
small
ideal for fan
pulleys
reverse pully
change direction using the belt
stepped pully
change speeds
regular pully system
pulleys rotate in the same direction
idler pully
allows for tension on pully belt
linkage
parallel linkage
transfers motion from one point to another
gears
spur gear
different sizes
bevel gear
rotates through 45 degrees
rack and pinion
rotation to linear motion
chain and sprocket
rotates in the same direction strong
idler gear
used to change direction of rotation
used to fill in gaps between
driver and driven gears
compound gear train
gear sizes determines speed
worm and worm wheel
high torque
very slow
ratchet and pawl
only rotates in one direction
