Last Day - Presentation

The last class for Electronics 10

We started with how to buy electronics parts online or in local store

we can get the list on professor mason's web site

we might need it in the future when we are doing more complicated electrnoics class

later, we did the presentation on our robot baby scropion

and it went pretty well

 The last thing we need to do for the class was to organize all the stuff we have and reture it

 We spent lots of time to break down the robot and put all the parts into the vex kit

and we just waited to be evaluate

That was all for electrnoics 10 class

hope everyone enjoys the class

and thanks to Professor mason for teaching us very valuable knowledge that we can use it in the future life

Day 18- Prepare for presentation

Last week of the class

We were told to prepare a presentation about the robot

The main three point is

• Big Fonts
• Dont put lots of the work
• Need to pratcie for the presentation

 And we left early to do the powerpoint at home :D

Day 16 & 17 - Competition Day

Day 16- Friday
Professor Mason gave one extra day to work on the project

We programmed more stuff in our robot
and we also make some change of the design of the robot


Day 17- Competition Day

We met at Cal State Fullerton fort the competition

We tried to make everything perfect and thought about lots of new ideas

But at the end

We change the program to the original, which is really simple

and the result was very surpised


that we got the right color and the position of the can was just fine

 and the can got stock into the car and the car drove to the correct place

Day 15- Finishing the final project

Last day for the project

We were suppose to test our robot today

But there are so many problems to be solved in our robot

We used most of the time to figure out the programming in our robot

Since we were so focus on the robot, me and my partner Jose forgot to take pictures

Our squarebot and search for the can, go towards to the can, and grab the can

but everything we test it, the robot rejects the right color of the can

and we used the entire four hours to do

But the good news is

Professor Mason gave us another day (Friday) to work on the robot

Hopefully we can finish the robot on time

Day 14-Vex Bot Project- Programming

Today's agenda was to write the program of the bot
we got the line sensor works, but at the end of the class
for some reason the car keep stopping at the same point, which mean the program ended


but for one time it work pretty good
and it actaully searched for the can and stop infront of the can
but it is unfortunate that we did not record the video

We hope we are able to finish everything on the testing day

good luck to us

Day 13- Vex Bot Project -Bulding Bot

This week is a critical week since we only have this week to finishing building and programming the robot
Today's schedual is to finishing building the robot
it took us to figur out how to put everything together such as the color sensor and the claw

We put a motor on the bottom inorder to turn the color sensor point to the ground or to the can

We also try to make some change to the claw so it is lighter and mor stable

The sensor and the motor all work as we tried

Now we just need to program the car to move, detect the color of the can, grab the can, and carry the can to the correct zone

Day 12 -Project Planning

Today, we were introduced a new mothoed of how to improve the efficiency of doing a project
After finishing the Gantt Chart
we started to do the work
first, I tried to figure out how the sonar sensor works

And we tried to make a claw to crab the cans
but we were not able to finish taht
so, we will finish it on Tuesday

Day 11

Today, we just need to finish soldering color & line sensor
and professor mason also explained how the competition is going to be

There will be few cans with different color being place in the middle
our mission is to make the robot determine which color the can is and make the can be in the correct section


later, I put the line sensor into the car

and it works!!!

even thought I burned out the one of the emiter

Day 10 - Building Sensors for your Robot

There are two sensors which are line sensor and color sensor
Since we have two people in a team, the work has been seperated
and I chose to make the line sensor


The line sensor is made up by the phototransistor

Phototransistors are phtodiode-amplifer combinations intergrated within a single silicon chip

Follow the schematic

With one of Emitter and one Detector
We will get

The one with the black tape around is the detector and the other one is Emitter
We will not able to see the light came out from the emitter, so we will need to have a camera point at it to see teh light

After finishing the circuit on the breadboard
We went to the fabrication room to solder these component

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
