Problem Statment

Design a cart that is safe, resilient, low-cost, low-weight, and user-friendly. The cart will be resilient by being strong and durable that can perform in multiple environments, extreme temperatures, absorbs impact and safely clears the ground. It will be user friendly by having free spinning wheels and will have a safe and efficient way to slow down and stop the cart. It will be light weight enough to be easily lifted, transported and collapsible. It will be safe enough for the riders, the dogs, and the bystanders. It will be single operant and be able to hold 2 average-weight people while being able to travel at speeds up to 30 mph.

Manufacturing in Motion

Team members Jose and Ryan with their work of art.
This week, manufacturing for several components were started:

  • Digger brake
    • drilling of digger plate
  • Spindle
    • material was cut
  • Mounting bracket
    • drilled
    • mounted (as shown in picture)
To be done:
Tap upright and thread front axle to have spindle ready for welding.
Receive remaining material and begin prep work for welding.

Steering design Completed

Steering for the cart has been completed, allowing integration of the rest of the cart's components to be possible.

To-do:
Use the updated bill of materials to purchase materials for:

  • Steering 
  • Suspension
  • Top frame

Moving forward

This week was very informative as we conducted analysis on our spindle/axel set up. Further test will be done to confirm our results.
As we move forward, completion of the rear wheel assembly is needed in order to finish welding the base of our frame. 
Below is an image of a new bracket needed to complete this design.

Updated Gantt Chart


Welding Setback

This week, the team was set back on welding due to design. A few of the cart's components must be redesigned in order to continue welding:
  • spindle
  • suspension arms (possibly)
  • reinforcement of front wheel (new design)
To-do:
Finalize design for mentioned components and run through our machinists (Mike and Joe) in order to proceed with welding.
