Lego Mindstorms Tug Of War

In the LEGO Mindstorms Tug Of War Challenge, teams had to create vehicles that would be able to win a game of tug of war against other teams' vehicles. Most teams built wheeled vehicles, but I constructed a vehicle with treads. Initially I built a two-tread vehicle with two motors, and this succeeded against a number of teams.

After losing to a team, however, I resorted to adding a third motor and four more sets of treads to my design. I also utilized a gear mechanism in order to derive more power from the motors. This did not prove to be much of an aid, however, due to the lack of friction on the classroom floor.

In a final effort to derive more success from my robot, I strengthened the back bracket securing my rear drive block. This ensured connection between gears, and helped it do a bit better. I also competed with other robots outside on different terrain to much better results. Outside, I won one race and tied most others.

Ping-Pong Gap Design Build Challenge

For the Ping-Pong Gap design Build Challenge, my group and I constructed a ramp that we used to propel our ping pong ball over the predetermined gap. Some constraints we faced in our build was a limit on materials due too predetermined selection and monetary limitations. Contrary to the bridges that other groups built, we constructed a ramp with which we propelled our ball across the gap. While we were able to successfully clear the gap, it was only once every few tries, leading to a low, but present, success percentage.

Superadvertising 2014: Jamie Casino Personal Injury Attorney

 - The commercial that caught my attention the most this year was a two-minute advertisement for Jamie Casino Injury Attorneys that ran during halftime. It tells a story about lawyer Jamie Casino, and his turn from criminal defense to personal injury attorney.
 - What made the commercial memorable was its sheer length and ability to tell a story. This ad ran for a full two minutes, much shorter than other ads which might only run for 15 or 30 seconds. This length of advertisement allowed for the telling of an in-depth story, which was much deeper than the commercials from major corporations.
- Commercials in the Super Bowl this year cost roughly 4 million per 30-second slot. This advertisement for Jamie Casino was aired on a local broadcaster however, substantially reducing the cost, although the network did not disclose the cost.
- Aside for paying for airtime, many other expenses ar included in the production of a commercial, including:
     - Actors (a couple hundred to low thousands)
     - Equipment (low thousands if purchased, high hundreds if rented)
     - Crew (high hundreds per person)
     - Catering (low hundreds)
     - Location Use (low hundreds)
     - Prop Use (very low hundreds)
- As the advertisement was for a personal injury lawyer, where service fees can fluctuate by thousands of dollars per case, the amount of "widgets" or services that must be sold to compensate for the ad is effectively impossible to calculate; however if we use the general cost of 5,000$ for a single service, and place the cost of the advertisement around 100,000$, The law firm will have to provide roughly 20 services in order to make up costs.
- Shortly after the superbowl, the Jamie Casino advertisement went viral online, reaching many more people for no extra cost, and sending the law firm very high very quickly in public status. This should provide an influx of requests for services, and it seems very likely that this ad will cover its costs directly, and will also have the added value of creating a popular image for Jamie Casino.

LEGO Mindstorms Robotics

Intro:
     In the days that we spent on LEGO Mindstorms robotics, members of the class were able to construct a LEGO Mindstorms Robot and program it to operate autonomously. Groups were tasked with having their robots complete courses by building an effective chassis and programming it with precision.

*NOTE: Due to my absence for the ending portion of the challenge, I was unable to capture photos of certain parts of the challenge, but was able to retain screenshots of my programming, and was able to capture certain photos after I returned.

Challenge Review:

     Challenge One - straight course

          - In this challenge, the teams' robots had to move forward in a straight line, covering a predetermined distance. Most people were able to utilize the NXT Brick's built-in programming suite, but a full-suite program was also possible, as shown in the photo included.

           - The robot I constructed featured a two-wheel system where the robot moved with two drive wheels and a back caster to provide balance. This allowed for an operation similar to "tank drive" where each side can be operated independently, allowing the vehicle to make sharp, in place turns. This, in tandem with a simple program (above) was able to complete the challenge with ease

           - Overall, the challenge was quite simple and i thought that it was a good start for the LEGO Mindstorms segment. My robot performed well and no changes to it or the programming seemed necessary.

     Challenge Two - "Bent" Course

           - The course provided would require a robot to turn at a sharp angle, but due to my two-wheeled system, my robot did not need any build changes to successfully complete the course

           - Using my robot's ability to turn at a fixed point, I constructed a program that would capitalize on that ability. I was able to send my robot into the bend, and have it turn in place to face the end of the course, and then simply move forwards. this simple program allowed me to complete the challenge very quickly.

           - The challenge seemed to be a good step up from the simple straight course from before, requiring builders to modify their vehicles for turning. My robot worked well on the course, and due to the lack of issues, I would not make any immediate changes to its construction.
