VEX Unit 2 Part Deux

Navigating blindly and based only on direction and speed is called?

• Dead Reckoning

• Loran navigation

• Best guess reckoning

• Best guess navigation

A robot with no feedback sensors using only program settings to navigate would be ?

• Dead reckoning

• Alive reckoning

• Car wreckoning

• I really don't know sorenson

What is empirical data used to program a robot to dead reckon?

• Time of travel guessed

• Time of travel measured with a stop watch

• Distance traveled guessed

• Distance traveled with a meter stick

Why is dead reckoning a poor way for a robot to navigate, especially over long periods of time?

• Motor speed drops as battery drains

• More opportunity for surface slip

• Gears loose mesh over time

• Inaccurate empirical data amplifies over time

If you know you are going to program 24 centimeter straight lines, a good option to make it easier is to create:

• User functions

• Multifaceted code

• Promo codes

• User modalities

What will the code shown cause the bot to do?

• Go Forward 3 seconds

• Go in a circle for 3 seconds

• Go forward for 5 seconds

• I have no idea Mr Green Jeans

Which line would you change to make it go forward for 9 seconds ?

• First Wait command

• Motor commands line 2 and 3

• Second Wait command

• Run a 'what if statement'

When programming straight line runs, what does DCONSTANT mean?

• Time/distance to travel

• Data rate constant

• Distance to target constant

• I can't make nothing else up

What is it called when the bot must make a decision or react?

• Branching

• Dancing

• Making Oatmeal cookies

• Looks complex sorenson

When we need the bot to react, we use what kind of programming statement?

• Conditiional

• Recreational

• Adversarial

• Demonstrable
