  Remote-Controlled Garden Seeder   Team 31- Beyza Kural, Syed Hussain, Nawaf Abulhaija Progress Update 03/09/2024 - 03/23/2024             For the work period of March 9-March 23, the team has begun fabricating the main frame of the device which will house all the electrical components and be used as the body of the device. The team began the work period by first constructing the main frame of the body to take essential measurements of any component that may need to be cut or resized after assembly. This initial step can be seen in Figure 1 below and depicts the initial assembly before measurements were taken to precisely cut the metal. Figure 1 : Assembly before cuts. The axle on the right drive-end of the device protrudes out too far to where the motor is not sitting on the right-side frame as it is on the left side. The device was also too long, and it was determined that there was a lot of unnecessary space in between the rear and front tires. The team decided to short

Remote-Controlled Garden Seeder   Team 31- Beyza Kural, Syed Hussain, Nawaf Abulhaija Progress Update 2/4/2024 - 02/17/2024      During the work period of February 4 th  – February  17 th , our team  worked on completing the disassembly of the  children's ride-on toy. We finished taking apart all of the components until we had the two drive motors, the tires, the axle, and the battery separated which are shown in Figures 3, 4, and 5, respectively. As previously mentioned, the motors are already geared to our desired speed so that will save our team both time and cost. After analyzing the aluminum frame of the ride-on toy, we decided that it would be best to use Aluminum 6061 which has high corrosion resistance and will be most optimal for our device's intended uses. We had 4 rods cut to our specific dimensions to make the frame, as shown in Figure 5, and these were purchased from a local metal shop. Since our last progress report, our team considered welding the 4 rods together

Remote-Controlled Garden Seeder Team 31- Beyza Kural, Syed Hussain, Nawaf Abulhaija Progress Update 12/11/2023 - 02/03/2024 During the work period of December 11 th – February 3 rd , our team made some considerable design changes to our project that should help our device be more effective, efficient, and reliable. Earlier in winter break, we sought to find any shortcomings in our device to limit any issues during the execution phase. We began by finding a mentor who was experienced in modifying and building remote controlled devices, had experience in connecting PCB boards, and could help us ensure that the parts we selected were going to be compatible together. We were able to find a mentor, Jarrett Jordan, who’s a content creator on YouTube and specializes in remote controlled vehicles. We met with Jarrett towards the end of winter break since he was out of town and went through our expected parts list. Some of the main issues we found were regarding our motor selection for b

Remote-Controlled Garden Seeder Team 31- Beyza Kural, Syed Hussain, Nawaf Abulhaija Progress Update 11/11-11/25      During the work period of November 11 - November 25, our team has been working on finalizing the design in SolidWorks so that we can have our CAD completed for our Design Review Report on December 2. Our milestones 1-3 are completed and we are now on milestone 4 in which we have the major components of our design finalized. Currently, our team is focused on the smaller details of the CAD such as fine dimensioning and the electrical layout. The electrical components include the power supply, wiring, motors, etc. The figure below shows the progress of our CAD design.  Figure 1. Updated CAD of Garden-Seeder       Based on our initial design concepts, we decided that our "Design Concept 1" would be most effective in meeting our client's needs. After conducting a design feasibility analysis, we were able to rank Design Concept 1 as the highest, in terms of oper

  Remote-Controlled Garden Seeder Team 31- Beyza Kural, Syed Hussain, Nawaf Abulhaija   Progress Update 10/28-11/11: During the work period of October 28-November 11, our team has been working on completing the analysis phase of our device as well as finishing up designing the parts in SolidWorks so that we can complete the full assembly before November 15, 2023. Our milestones 1-3 are completed and we have conceptualized our design with all the parts selected. We completed some preliminary sketches for the design and settled on a design that utilizes a top loaded motorized hopper with an aerator in front. The preliminary sketch of the device can be seen below. The device will include wheel covers as well as a rubber back to smooth out the surface as seeds are distributed. The hopper will be pyramid shaped to create a funnel in which all the seeds can be placed without any issues getting stuck. The hopper will include a small motor which will control the flow rate of the seed

  Progress Blog #2      Beyza Kural, Syed Hussain, Nawaf Abulhaija Major Constraints Technical Goals Size 2x2 Feet Weight Sufficient Motor/Light-Weight Design Coverage 20 Pound Capacity Sensor Range 500 Feet Power Source 30 Minutes of Continuous Use Different Terrains Rigid Structure and Fully Remote Remote Operation Wide Angle Camera Soil Depth Perforate 1/2 Inch Maximum Seed Size Seeds Up to 1/4 th Inch in Length Soil Moisture Optimized for 30-70% Soil Moisture Wheel Type Spiked Wheels Budget $600 The device faces several key constraints in the design that we must consider. First, its size must be compact enough to navigate through obstacles like trees and be stored easily. To achieve this, the target dimensions aim to keep the device's length and width under 2 feet. Weight is another critical constraint, as the motor should handle the maximum load while keeping the design lightweight for efficiency. The device must also minimize seed refills, aiming to hold at least 20 pounds o
