Accomplishments this week 1. Prepare for presentation Edit slide and draw block diagram 2. Add CAD Simulation of Book and music stand 3. Integration Research on using AWS to transfer signal to Raspberry Pi, needs to look more into that to learn how to integrate with software 4. Additional Feature Implemented button Read more…
Accomplishments this week 1. CAD Simulation Reverse flipping CAD simulation 2. Integration Implemented button control on Raspberry Pi to control motors Research on using AWS to transfer signal to Raspberry Pi, needs to look more into that to learn how to integrate with software Progress for schedule: On schedule Deliverables I hope Read more…
Accomplishments this week 1. In-lab Demo Prepare in-lab demo Get feedback from in-lab demo 2. CAD Simulation Through the in-lab demo feedback, I slightly updated the CAD simulation so that the flipper does not interfere with the book at the begin and end stage. Implemented reverse flipping CAD simulation Progress Read more…
Accomplishments this week 1. Electrical Component Rewrote the hardware code to turn servo and stepper motor code in order Able to do position control on stepper motor in both direction Still working to do position control on servo in both direction Code Link 2. CAD Simulation Initiate CAD Simulation by Read more…
Accomplishments this week 1. Setup Electrical Component Plug-to-wall DC voltage source is delivered on Wednesday, along with the entire hardware items left in the ECE lab before spring break. Spend some time check and re-wiring the circuit. Then set up the Pi again on local WiFi network, similar to previous Read more…
Accomplishments this week 1. De-scoped Electrical Demo Without the lab equipment (voltage source, multimeter, oscilloscope), I am unable to test if I am outputting the correct pulse signal to the stepper motor. Decide to use the Raspberry Pi to control two stepper motors and one servo to do the intended Read more…
Accomplishments this week (Including spring break) 1.Setup Raspberry Pi Setup the Pi’s network with CMU Device and finally able to ssh into the Pi Test transferring file in and out from Pi with scp Enabled I2C and install adafruit-circuitpython-motorkit following the Adafruit stepper motor tutorial 2. Control stepper motor with Raspberry Pi Read more…
Accomplishments this week 1.Updated CAD Shaft The CAD shaft has left end height 10mm, right end right 30mm, and length 200mm. The left end from the figure below is where M1 lift the shaft. The right end is where the servo will be assembled to control the wheel. The extrusion is Read more…
Accomplishments this week 1.Change M2 from stepper motor to servo When searching for appropriate M2, the limited torque M1 can bring is my big consideration. A searched for many stepper motor models, but all has large dimension (around 40mm * 40mm) and large weight (around 350g). In order to flip Read more…
