This year, Trinity Dragons Robotics has reached for the stars. Our innovative designs have brought us to a competitive level on a world stage. As the Starstruck season was unveiled, we knew that to achieve a competitive skills score we would need high hanging capability. Understanding that the 12 points available would be crucial, we set to work designing our robot around this element. Consequently, two major aspects of our robot, T.R.A.S.H. and the Dragon Drive, were created specifically to assist our hang.
To begin with, we designed and built T.R.A.S.H. to assist our hang. As this year’s game requires our robot to have the capacity to throw large clumps of stars and cubes, we needed lift assist in the direction of our throw. However, this creates force that opposes the direction of our hang. Understanding this, we determined it would be wise to implement a “Tension Release Allowing Successful Hanging.” We wrap rubber bands around the four-bar in such a way that the lift is assisted. Next, the loose ends of

At first, we tested an x-drive to evaluate its effectiveness. Sadly, this specific drive proved incredibly difficult to run in autonomous. Additionally, it was not nearly as fast as we needed it to be. With this knowledge beneath our belts, we created what we call the Dragon Drive. While it is more commonly known as a U-drive, we had never seen one before as they are not used often, and so we renamed it. The Dragon Drive consists of two rear wheels in an x-drive shape and two front wheels in the tank drive configuration. After evaluation, we determined that this drive was as fast as a tank drive, but had better turning efficiency. Additionally, and more importantly, the geometry of the back of the drive lines up perfectly for hanging. This design enabled us to line up and hang quickly in autonomous and driver
The concert that I attended was a charity concert, which was organized in Boston at a local university there. The South Asian Student Union of Harvard University organized the concert. I happened to be in Boston and this particular concert was organized for benefit causes such as using the proceeds of the concert to fund a number of poverty alleviation projects in South Asia. The concert was organized in a rather big room, which had a very big podium, as well as at least 500 seats that had been placed in it. Therefore, the overall hall where this concert took place was a typical auditorium setting with seating and a stage at the front. The concert promoters talked about different cause benefits related to alleviation of poverty in South Asia and that’s why the concert was organized. The organizers also informed the audience that the musicians wore traditional clothing so that the audience members could also have a good insight and understanding of the South Asian culture. All of ticket revenues for this concert were then given to a number of charities which then would use those funds to assist the different poverty alleviation programs in the larger South Asian region.
On November twenty-ninth, I attended APSU Student Recital at the George and Sharon Mabry Concert Hall. The performance consisted of only three pieces, yet both were met with enthusiastic applause and praise. When I attended the performance I hear and seen exactly what I expected which were student performing amongst their peers. This particular performance was different because I never experience a student recital. I was very pleased by the performance I thought it was very entertaining and interesting.
For this quarter, I watched the top band at Highland Park play. They were playing because they were invited to play at a competition in Peoria and they wanted to practice playing the three songs to an audience without any breaks just like they would in the competition. I thought it would be an excellent opportunity to hear a really good high school band perform. I also knew many of the performers from an orchestra I play in called Symphony Orchestra at Midwest Young Artists. The band played very well and the experience taught me many different things that I could improve with my ensemble playing.
Last April, I and my husband went to watch the concert by Tedeschi Trucks Band because my husband's cousin was a back volcal of the band. He gave us a backstage pass and introduced us to the members of group. It was such an honor to meet the grammy award artists! The show was awsome. Susan Tedeschi was the main vocal and her voice was so powerful and soulful and her husband Derrek Tedeschi's guiter technique was amazing. Of course, my husband's cousin Mark's voice was great also. He has been telling me about Mark's voice and now I know how great his voice
Making the car and wheels too light caused problems, though, that’s why I paid close attention to the way my car was proportioned and chose four wheels on each axle all the same size. The reason why I chose four wheels all being a large size for each axle is because larger wheels cover more ground than what smaller wheels can do in the same amount of time.But, both sets of wheels will not affect how a car does at rest. When an object at rest (The car) will remain at rest, the more wound up the string on the mousetrap car is the more force that will be produced on the impact of the hatch releasing causing more acceleration, the reaction to the string causes the force to fly forward. But I also didn’t interpret the way I built my car the way everyone else had, originally my car would need the arm to be set to actually accelerate so that when you pushed down/load the arm, the string is would be compressed, causing the vehicle to accelerate forward. But that changed because of the reaction my car would have with the original setup, spinning in random directions because of how light my car was my second test
On October 31st, we finally shot up our rockets. Some of the rockets went well as we predicted; some others did not. Our rocket was launched three times in total, and out of all three, only one launch managed to get the parachute out when it was needed. In this report, I am going to write about what relationship the rockets have with Newton’s three laws we have been studying lately. I will connect each of Newton’s three laws with the rocket launches we had.
Our prototype car did perform as desired. So we made improvements by, making the vehicle longer, replacing a crayola pencil with a fishing rod, and creating a wall to store more potential energy by bending creating a spring-like motion with the fishing rod. We put the aluminum tubing inside the wooden frame. Then, we put the graphite in the aluminum tubing and put the axles in the tubing with the
Along with Eaton and Cummins, Dana has engineered what is touted to be the fastest, lightest and most efficient drivetrain to help fleets maximize the benefits of
This innovation offers numerous points of interest: less demanding lifts, smoother drive, and diminished wear on the motor, gearbox, and power through pressure. Quick moves, with high effectiveness. Less power is required for lifting while more power is accessible to move the truck, bringing about lower fuel utilization and less wear'.
Surprisingly, during the song “Yonsei,” I noticed that there were 7 female performers and 3 male performers. Having done some background research before attending “Setsuna,” the Kyodo Taiko Spring Concert, that taiko drum playing was used as a “battlefield instrument used to intimidate or scare away the enemy,” or at “appropriate religious events” (Taiko Resource). By the 1500s, while in combat, a single taiko drum was used to authorize orders and communicate movements (Taiko Resource). An individual soldier would support the taiko on his back while two other soldiers perform various rhythms to execute commands on the battlefield. Apart from the military application of the taiko drum, taiko drum performances were considered a luxury among “imperial
The industrial robots are applied in all branches of the industry. The highest level of application is in the automobile industry, but the number of installed robots is increasing in other industries as well (Karabegovic, Dolecec, Husak, 2011).
Recently DBR released their advanced robotic prototype at an international tradeshow. Industry experts have termed this prototype as the most advanced robotic system and also suggest that this prototype is at least 5 years ahead of what DBR’s competition has to offer. Because of this reason, DBR fear that their competitors could try and steal their
The task is to tug the tail within the body of the robot, preserving the normal reaction force with the ground and then releasing it as it produces the energy to lift the robot body off the ground.
Abstract- In this paper, the results of the work on the development and implementation of steering mechanism is presented. The proposed approach is to construct a vehicle with 90 degrees turning wheels through "changing pinion over the rack" steering mechanism. The steering mechanism uses rack and pinion in defined gear ratios.
This wheel absorbs the kinetic energy from the differential through this mechanism, hence retarding the vehicle.
