This week, I prepared the final presentation and gave speech. Also, I tried to debug the github issues we were having with Ritu and wired the ultrasonic sensors to count the number of items we are collecting. Finally, I installed the motor on the roller and cut the hole on Read more…
For two weeks, I have been mostly working on motion control. First, as our original motors had low torque for our robot base, we switched to motors with higher torques (6.5 kg*s/m). As soon as it came, Hirani and I put the motors in and tested them, which turned out Read more…
This week, I have mostly spent my time trying to debug dc motors. On Monday’s interim demo, we found out that the robot cannot move when it is on the ground. Plus, some of the motors would not run at all. We thought the battery was an issue, but, later Read more…
This week, I spent a lot of time finishing up the build for our robot. First, Hirani, Ritu, and I were able to attach the motor mounts on the robot base for our pick up mechanism. Then, Hirani and I tested out the raspberry pi hat with DC motors and Read more…
This week, overall, I spent more than 12 hours to work on the capstone project. First, I finalized all the parts for the conveyor belts. I’ve decided to use 12v DC motors mounted on the bottom aluminum extrusion with 20:48 teeth pulleys. I chose rubber strips as a belt since Read more…
This week, I spent most of my time working on building a robot base with Hirani, ordering additional parts, and researching Simultaneous Localization and Mapping (SLAM). During building sessions, we cut aluminium extrusions from metal shop at TechSpark after finalizing dimensions of our robot. Then, we waited a few days Read more…
From February 25th to March 9th, I’ve completed a number of tasks so that I could be prepared to build the robot after the spring break. First, I’ve created a CAD model of our robot. This will be the guidance to building our robot base and was added as figures Read more…
For this week, we had a design review presentation on Monday and Wednesday. Due to the absence of work sessions within classes, we had this week to be somewhat flexible for the parts ordered to come and identify any potential issues with Jetson Nano and robot base designs. My original Read more…
This week, there were many tasks I personally accomplished on the project. First, I worked on design presentation slides and then did some research on a camera module compatible with the Jetson Nano Orin Developer Kit as the following: https://docs.google.com/document/d/1qags4xzWa6l6wguN0HfArgNEiNxMWlKxdvZhU5k9h0o/edit?usp=sharing There were many great options suggested by Nvidia, and E-CAM50_CUNX Read more…
This week, I primarily researched different pick up mechanisms for our garbage cleaning robot in order to finalize our parts ordering list. Hirani and I are collaborating on a design sketch for the upcoming design presentation. Along with the process, we became uncertain of using a scoop mechanism to pick Read more…
