This week I created a BoM for our project. Specifically, I focused on researching motor chassis options for our project to make sure we choose something that meets our load, speed, and size requirements. After comparing different platforms, we decided to use the Hiwonder Large Metal 4WD Vehicle Chassis because it supports around a 5 kg load, has suitable speed for indoor navigation, and is mechanically stable enough for our system. It’s also compatible with Raspberry Pi/stm32 control and supports encoder feedback, which will be helpful for motion control and navigation accuracy. Overall, it seems like a strong fit for both our technical needs and our integration plan.
I also worked on the design presentation slides, mainly focusing on the motor implementation section, test/verification section, and the project management portion. I outlined how we plan to wire and control the motors, what components are needed for integration, and how testing will be staged once the hardware arrives. For the planning section, I helped organize our timeline, task breakdown, and milestones so we have a clearer roadmap for the next few weeks.
Right now we’re on track with our schedule and haven’t run into any major blockers. All required components have been ordered, and once they arrive, we’ll begin testing immediately. The goal for the next phase is to verify motor control, load performance, and basic mobility before integrating sensors and camera. Really looking forward to working on the motors!
