Day 9 - Vex Programming

Today, we took out our square bot and started to program it
first we will need to plug the cable into the PC

And you might need to download the prolific driver for the cable


plug the other end  to the serial port of the vex car

clear the memory in the car and you are able to start the programming

Our first goal is to get to the red box

The first method we are going to use is just estimate the distance and guess the amount of the the car will need to travel each section

we just need
power of the motor * amount of time it turns

this method is not really accuarte
for most of the student
the card is not even on the track but going all over the places


After done with this one
we were partner up with one other person
my partner is JOSE
and we will modify his vex car to do the next experiment


we will extend the front wheel axis so we are able to put the roataional sensor in

The red part is the sensor

and this time we will use how many rotations turn inorder to calculate the distance it travels

That is how our car goes
We were kind of out of time
so for few sections we just guess the number of roataion
and that cuz the car went wrong in the middle
