Letβs discuss the requirements of the vehicle in chapter 2:
- two sensors and
- two motors and
Possible alignment of the motors and the sensors: a) motor and sensor are in the same side b) motor and sensor are diagonally placed c) both the motor have the sensory input of the both the sensors
But c) is pretty much vehicle 1. Why? because, the direction of the source doesnβt have any affect on it. So, it will run based on the intensity of the sensory input. (i.e. light, temperature). So, basically it is same as vehicle 1 with an extra motor and sensor.
Instead of writing The Vehicle 2 (a) or (b)
over and over again, I will be calling The Vehicle 2(a)
as Tony
and The Vehicle 2(b)
as Billy
But a) and b) have some interesting feature. Based on where we put the sensor they acts very differently. In
a) Tony moves away from the source: as Tony moves away from the source the speed decreases
b) Billy moves toward the source: as Billy moves toward the source the speed increases
Why does it happen? The underlying concept is related to circular motion and centripetal/centrifugal force:
If the two wheels are rotating at a different speeds, then it will create a turning effect. Our
Tony/Billy
will move in a arc with different radius. Because, the difference in rotation will always causes it to move toward the slower wheel
Lets try to put it into equation (The physics is not strong with this one! π«£):
We have for proportionality constant ,
(i)
(ii)
and the overall velocity should be
But the turning radius will be,
or,
So, in conclusion,
a. Tony
will always move away from the source. Until he reaches far away from the vicinity of Source
he will be restless. Hence, he is a COWARD. If someone disagrees with the authors analogy, I guess if Tony
were to scream Oh no! Oh boy! Oh boy!
. Seeing this one could comment,
The only thing he chases is away!
But in case of Billy
,
b. Billy
will always run toward the source. As he moves toward the Source
his speed will increase. Hence, he is a AGGRESSIVE. If someone disagrees with the claim, we could put some insulting
line in to the Source
, like: Oh you think you can catch me...! comeon...! comeon...!
and when he bangs on the source, one could say,
When people said βface your fears,β they didnβt mean
headfirst
!
N.B. There are people who donβt hide from their fear. They march on. Cowardice is really just a refusal to confront discomfort and push limits! (I took it from David Goggins). You hear that Tony!
