Week 7 - Journal
Mini Robotic Arm
Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)
Title of Media
I see this project on YouTube and I'd like to do as it nearly like to the concept of mechanism of my final project bionic hand
Tool Chain
Which software/machines/materials did you use in the assignment? Why?
Software used:
TINKERCAD to design & simulate circuit.
Arduino IDE to upload the code to the Arduino
Components:
Arduino Uno
Servo Motor
Potentiometer
IR sensor
Jumpers
Breadboard
wires
Design/Preparation Process
Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?
2022-04-02 03-31-51.mkv
When the value of resistance of potential meter is greater than 512 ohm
first servo rotate with angle 90 degree
if less than that value the second servo will rotate with the same angle
Development/Implementation Process
Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?
If IR sensor detect object servo 'll rotate 90 degree to contract hand.
else servo 'll rotate 90 degree to extend hand .
Conection..
5 v Adaptor--> negative side to same line of breadboard which connected to the negative of Arduino uno
positive side to lower positive line of breadboard
servo_1--> connect the brown leg to negative line in breadboard.
connect the red leg to lower side positive line of breadboard
connect the orange leg to pin2 on Adriano uno to control servo
servo_2--> connect the brown leg to negative line in breadboard.
connect the red leg to lower side positive line of breadboard
connect the orange leg to pin4 on Adriano uno to control servo
IR-->VCC to upper side positive line of breadboard
GND to same negative line in breadboard.
O/P to pin3 on Adriano uno to
Potentiometer-->VCC to upper side positive line of breadboard
GND to same negative line in breadboard.

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?
During Monday lecture
Relay connection confused me but finally I used it

Overcoming Challenges
When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?
I didn't have straws to as tube for wires as finger tips so I used the inner cavity of cardboard

Final Project
How can you use the skills and knowledge that you've acquired this week in your final project?
This weak help me to connect servo motor and understand the mechanism of hand
