Build Session – Week 4, Part 2

Saturday, January 31, 2015
On Saturday, January 31, MARS/WARS reached a great milestone for the build season, as the team consolidated their fabricated components into a robot assembly. Although the bot is not complete in its entirety, it is currently equipped with a functioning tote elevator and swerve drive chassis. This significant accomplishment by the team is the turning point in MARS/WARS’s season as it means that our energy will now be devoted to evaluation of existing components and determining how our robot can be improved. With the completion of the major systems of the robot, the programming team can develop and implement more specific programs, having distinct indication of the robot’s composition.

As the open house draws closer, MARS/WARS continues to make preparations to welcome the community into its facilities to observe the team’s work. The event has been publicized in the local media, on the school’s website, and in the newsletter and organization of the tour route has taken place. The team has contacted the Mad Hatters, an FLL team founded by MARS/WARS, and invited it to exhibit its Lego Mindstorms robot. The Mad Hatters will also give a presentation about their recently completed season, during which they advanced to the Central Championship Tournament at the University of Illinois. Significant progress has been made with the lower frame of the robot and it is nearly ready to be painted. The first swerve module has been finalized and reviewed and construction of the other three swerve modules has been approved. MARS/WARS is excited about the advancements it has made thus far and the team is able to begin constructing the robot assembly in the next few build sessions.

Build Session – Week 4, Part 1

Tuesday, January 27, 2015
During the Tuesday build session, several team members traveled to the practice field at Metamora Industries where they used more specialized machines to fabricate swerve parts. In MARS/WARS’s primary shop, the mechanical team used welders and the CNC machine to build parts for the tote elevator and swerve frame. The electrical team continued to wire components and contrive the layout of the electrical board.

MARS/WARS began its build session with what team members like to call “Thank you Thursday,” a time during which each person expresses gratitude to someone. Both humorous as well as heart-felt thank yous are expressed, with replies ranging from “thanks for putting up with me” to team members thanking individuals responsible for founding MARS/WARS. Chassis fabrication continues as team members machine the lower housings of the swerve drive with the CNC mill and assemble gearboxes for steering components. As the modeling team continues to develop parts for fabrication, it has become apparent that the team needs a method by which prints will be organized and stored. MARS/WARS team members worked during this build session to develop a protocol for the depository of these documents. Several more prints were drafted during this build session, which included documentation of a barrel lifter as well as a concept for a three wheeled frame.

MARS/WARS is approaching the end of prototyping as they work during their build session on Thursday, January 15. Observation of the modelers would depict the assembly of entire robots, as weight tests are being simulated on the designs. The mechanical team has finished several prototypes, including a claw mechanism and chain to lift multiple tubs. In addition to this, a pneumatics board is being fabricated as the team is considering their usage and would like to evaluate several components of their performance. The mechanical team also restocked the toolbox with soy sauce because they were running low. MARS/WARS found great success with their swerve drive in the 2014 season and intends to use a swerve drive again. Programs for its operation are currently being developed and will be tested in future build sessions. Preparations for driver tryouts are being made as analyses for the driving test are currently in development. Following the build session, a driver practice is being conducted.

3 Weeks to MarsCar Presentation

Wednesday, January 14, 2014

The MARS/WARS junior varsity team continues to meet as they work on the MarsCar outreach project. They conducted a build session for the vehicle on Wednesday, January 14. The bed on the original gator vehicle is unable to be used due to the fact that it is too large. To resolve this dilemma the team is building a custom bed from wood to install on the vehicle. Fabrication of this bed was continued during this build session. In addition to this, modifications to the original drive train has left the gator with a large turning radius. The team also spent this build session working to adjust the steering components of the vehicle and enable it to make sharper turns.
