11/23-11/30

This week we prepared for final presentations and worked on the rough draft of the sub-team report. We did not meet until Tuesday as it was Thanksgiving weekend, all work was done online.

Craig finished printing models of the gears we plan on using for our propulsion. A mock-up of the motor was printed as well but there were some difficulties in completing the second half. The purpose for our prototype is to asses the space limitations our current design has with the dimensions provided.

We completed the Bill of materials and are hoping to get funds to at least cover the motors and most of the cost of the gears. Craig plans on using parts from his fathers shop for most of the braking components, which we are continually working on. We are planning on completing the braking design and part of the build over winter break.

11/16-11/23

During this week we brainstormed on ideas for redesigning braking. So far we have went through brake disks, band brakes, and motor braking as possible options but spacing of our current design will not allow for band brake or disk brakes. Additionally considering motor braking we concluded to not risk damaging the motors as they are expensive.

We spoke to our advisers for possible options and are looking at modifying a brake caliper to come in contact with the rail for braking.

Design of propulsion is complete. Plan on 3-D printing the gears to attach to model being built by steering/bogie team.

11/09-11/16

This week we worked on beginning a draft of the final report and organizing information in preparations for presentation 3.

Braking continues to be a problematic issue within our system. We were able to find a band brake that could fit with the current design of driving shaft, however we have yet to determine if brake will be sufficient to stop the system. Additionally we are working on using motor braking as another option. We plan on working closely with the Mechatronics team in further progression for motor braking.

11/2 - 11/9

This week we worked on assembling a list of parts needed for next semesters build of propulsion and braking systems. We received a quote for motors that we plan on using for propulsion.

We plan on using spare parts from the assembly of the bogie in order to create the proper mounting for propulsion.

We continue to work on braking. We planned on using one actuator for both band brakes, but mounting in the middle of the entire bogie can prove to be difficult. We plan to discuss this more at length with steering and professors as we go forth.
