This week marks the end of building our simulation and the start of analysis. Claire and I both finished the chassis and Z-axis parts and I integrated the parts. Below is our completed robotics system: I started looking at the possible analysis we can do for some trade studies. The first design decision is the choice of material for our vertical support rods. I first applied the appropriate materials to all the components on the gantry and used Fusion 360…
This week Claire finalized the Z-axis components and started integrating it with the gripper. She has also been working on simulating motion for the two components. Next week, she will finalise the details of the gripper. Arka has continued to work on his colour classification code, and fine-tune his object detection code with the higher quality photos we are now using for our data set. I (Maxine) has finalized details on the chassis. She has also begun integrating Claire’s components….
This week I worked on the rest of the timing belt assembly for the Y-axis, and the full chassis frame. I added features such as the camera mount, the lights for a stable lighting condition, and the compartments for the sorted resistors. I have also begun to integrate the Z components that Claire has been working on. Here is the progress I’ve made so far: Since I’ve had a lot of time to work on capstone during this quarantine, we’ve…
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,…
This week our team has made significant headway on the new direction our project has taken. Arka worked on fine-tuning his edge detection code and gathered more datasets to test his object detection code. He is still missing the cable to set up the new RasPi so he is currently testing on his computer. Next week, Claire worked on the Z-axis component. She has now built the rack-and-pinion and motion linked the components together. She has also started working on…
This week I continued to work on the XY gantry simulation. Being more familiar with Fusion360 now, I worked more on simulation movements and enforcing joints. I now have fully completed the X components along with the timing belt and steppers. The gantry currently totals to 55 components with 131 bodies. Here is the animation of moving along the X-axis. And along the Y-axis: Per the schedule, I am on track to finishing the gantry this week and I will…
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…
Past Week To Do: Embedded: Reset up Rpi Computer Vision: Work on edge detection to find color bands on each resistor Work Log: Embedded: Need to place order for the right cable to connect Rpi to my computer Computer Vision: Working on playing with different edge detection techniques to get best result at color band detection Next Week: Embedded: Set up Rpi and get back to the point pre-Corona Crisis Computer Vision: Figure out a decent edge detection technique that…
This week our team has settled back into our respective homes and had more time to explore the adjustments to our project after switching to remote. Claire and I (Maxine) worked on Fusion360. We both started with basic tutorials to learn the fundamentals of the software. The current goal is to do our best to simulate the implementation plan we had previously. We thought about switching to a robotic arm since there are more online resources on how to build…
After settling back in Hong Kong with my 14 day quarantine, I had some time to do a more in-depth exploration of Fusion360. I followed several tutorials and started to get the hang of Fusion360’s fundamentals. Claire and I had a discussion whether we should switch to simulating a robotic arm instead of the gantry approach for a few reasons. The gantry approach was what we were going to do in implementation before the virus hit. We were familiar with…
