Overview:
I am planing to use STM board to control shoulder massage helper, basing on control the speed of Robot Arm Clamp Claw. And use joystick to control the strength level of it. I will use the button on LPC board to save the user’s using history, and be able to recall the strength changing.
Peripherals:
Robot Arm Clamp Claw
micro servo 9g sf0180motor x2
STM board
External clamp claw(to massage more area) Didn't find
TM74
Joystick
9 v alkaline batteries and battery chip
power supply module for breadboard
​
Software Design
I am going to use I2C to connect the motor to GPIO pins of STM board. The pin would generate PWM signal trigger by interrupts to control the strength. Joystick would be able to change the strength by moving left and right, up and down would be able to recall one changing process,up set favorite, and down recall favorite.
Goal:
Fully connecting the arm clamp claw to board with low delay.
Increase the upper bound of strength, and can make it as fast as possible.
Modifying the claw to make user’s experience more comfortable.
Add more massage function if time available.

Weekly update
-
2/21 Assembly the gripper kit and decide to use glue gun to make the peripheral part of gripper.
-
2/28 Setting up basic I2C and Uart initionalization.
-
3/5 Set up PWM signal and joystock interupt.
-
3/13 Make the gripper can work automaticly and left right button can increase or decrease the frequency, set initial version for remember and recall.
-
3/19 Finish TM74 , fail to use ultrasonic sensor by it need too much TIM, which would affect other function, and the project is done.
