Schedule This week we are scheduled to work on integration. Progress This Week This week Maxine and I were able to integrate the gripper with the gantry. We then decided we wanted to get a head start on the design document and analysis. Since I was originally responsible for the motors, I took on stepper analysis for the 6 steppers we used in out system. This included how XY distance would be moved with each step, how a half-step might…
Schedule This week’s task was to work on the Z rotation. The gripper was originally offloaded across these 3 weeks, but this week I had some additional time to work on it. Progress This Week Since Maxine and I looked into how to integrate this week, we realized that integration with how we split up the work was going to be quite seamless. She looked into how to mount the bracket on my rack and pinion structure, and with that,…
Schedule This week’s task was to work on the Z linear motion, and along with Maxine, finish the gripper. Progress This Week This week, Maxine and I made a couple adjustments to the schedule. Since the gantry turned out to be a lot more components than we expected, I’m now responsible also for the gripper. I was able to finish the Z linear motion. First, I made a rack and pinion structure. And since I found it likely to be…
Schedule The newly updated schedule can be seen in our weekly team meeting. From this updated Gantt chart, this week’s focus is scoping and learning about Fusion 360 and seeing if it can work. Progress This Week This week, I was able to accomplish what our Gantt chart set out. I set up Fusion 360 and tried to follow a few tutorials. I realized that creating each component from scratch was going to be very time consuming and quite difficult….
Schedule Throughout Spring Break, COVID-19 hit hard, and while I was on my last days on break, we received word from the university that there will be no academic reason to come back to campus and we were strongly encouraged to go home. This is going to be a pretty big hardship in our hardware-based project. Progress This Week This week, I packed my bags and moved out of Pittsburgh and back to Taiwan. Besides that, our capstone has been…
Schedule Per our Gantt Chart, this week I was supposed to set up the servo motors. However, I’m lagging a bit behind this week, partially due to the short week, but my other classes are also taking up much more time than expected. Progress This Week This week I was able to work more on the stepper motors. I wrote some python code for the servos but have not tested with the Raspberry Pi (will have to coordinate with Arka…
Schedule Per our Gantt Chart, this week I was supposed to set up the stepper motors. I was able to do some of it, but a lot of this week was focused on the Design Proposal. Progress This Week This week, besides working on the design proposal slides, presentation, and report, I was able to obtain the stepper motors and drivers and check whether or not I could interface them with an Arduino Uno. Using an Arduino Uno allows me…
This week I did a lot of research into part purchases with Maxine. I looked into the motors, and how to control the different parts of the mechanical system. We knew that we wanted 3 stepper motors to control the XY motion, some way of gripping, some way of rotating the gripper, and a way to control the Z motion (as mentioned last week). After research, we decided on a NEMA 17 with a A4988 stepper driver for ease of…
This week was the first week we began working on our project. After our proposal presentations, we received some feedback about our confidence level with the robotics portion. We are excited to tackle the challenges, but as we mentioned in our proposal, we are definitely not familiar with robotics. We (Maxine and I) wanted to start planning the 2DOF XY movement portion while doing some more research into the gripping mechanism. (Jiaqi had suggested a prismatic joint for our claw…
