The Biological
Locomotion of
Snapping Turtles
Hunting
• Snapping Turtles hunt their prey
by opening their mouth, and
wiggling their tongue to lure
prey into their mouth. They then
powerfully clench their jaws
around their prey.
• They clamp onto their prey with
a force of about 1,500 Newtons.
• The average human's biting
force is around 1,100 Newtons
How My Robot Relates
• The Lego Robot I have created
performs a similar task. It awaits
with a raised “jaw” for
something to set off the
ultrasonic sensor. Once
something passes through, the
“jaw” closes.
The Simulink Function
• I’ve attached my Simulink model
to show how it runs. It’s fairly
simple, when the ultrasonic
sensor detects something that
decreases the distance between
it and the ground, the motor
begins turning which closes the
jaw.
More on my simulink function
• The motor speed it set to –100
when the conditions are met
• The encoder turns an average of
75 degrees to fully close the jaw.
• It hurt
