156B Week 9

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

We updated the code to run for 3 fingers. the global reference frame function is implemented however still need to be calibrated and tested for 3 arms. on the mechanical side, the limit switch is placed, added extra support, and created the whole circuit on a breadboard. PCB has been ordered and will take a week to arrive. the new Motor Driver has been tested and we will be using 12V for the stepper.

Accomplishments from Previous Week

• Code for 3 Fingers with Global Reference Frame

• Calibration & Position Reset Button on GUI

• PCB designed and Ordered

• Full circuit assembled

• New Motor Driver tested

• Added support to the full assembly

• Installed the Limit switch

Goals for This Week (list names after each item). Use specific and measurable objectives.

• test full 3 finger code

• install the PCB and finalize the circuit

• add voltage divider for servo and limit switch

• calibrate all motors to be as precise as possible

Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate the date of comments and if via email or in-person)

• Create a step by step instruction on assembling the robot

Risks and Areas of Concern:

• Timing Belt Slippage

• Voltage difference between Servo and Stepper motor

• Calibration Method

Budget
