Rodney the skateboarding robot :: Robotics

Rodney the skateboarding robot My project is Rodney, the robot skateboard, targeted at kids who want a cool skateboard accessory, and parents who would most likely buy one for their kids. Similar designs are a handle-like device with wheels that pulls a skateboard or roller skates, and the Segway. I have studied these designs, and a brief history of skateboards to better my understanding of how to make my robot work. The first design has a forward/reverse options for the motors and is turned by turning the board or roller skates. It is practically just a way to use the skateboard without using much energy. Segway ® Human Transporter (HT) can self-balance because of a technology called dynamic stabilization. Dynamic Stabilization works by using solid-state gyroscopes, tilt sensors, high-speed microprocessors, and powerful electric motors performing to keep it balanced. The skateboard originally in the 50s was conceived as a way to surf on land, whenever there was bad surfing weather. It started out as roller skates nailed to a wooden base. Then a bicycle company in the early 70s built better boards with flexible mounts for the wheel axis, and thus was born the modern skateboard, with grip tape for more maneuverability and painted designs and logos on the bottom of the board. Rodney is a two-part robot, one is the controller for Rodney and the other is Rodney himself, the maneuverable part. The controller consists of flat platforms with four walls of beam pieces. It has a RCX 2.0, and three touch sensors. The Rodney also RodneyBeta the skateboarding robot has an RCX 2.0 and four motors in a car-like design. He has beams and panel pieces connecting the motors together for additional stability. Rodney was successful at pushing my skateboard forward, reverse, and even turning. He could move the skateboard by itself at around 5mph and slightly less with added weight. The maximum weight that it can hold is about 2lbs. The remote controller has a range of around 10fts, and when it is out of range Rodney continues doing the same function that it was doing previously. I found that sometimes wheels may fall of Rodney, and occasionally he slides out from under my skateboard. I see that the alpha form of Rodney can that at least three forms, one being the

American Military Might

Present American military and law enforcement agency might has been put to a test both internally and externally in recent years. With the creation of the Department of Homeland Security, which was born, in large part, in response to the events of September 11, resources for battling terrorism have increased. Nevertheless, the wars in Afghanistan and Iraq have shown that the United States is not adequately equipped militarily to confront and defeat sophisticated terrorist operations.While there has been a decrease in  terrorist acts occurring in the United States, acts of terrorism abroad have not decreased. Clearly, the adequacy of military planning and military preparedness has been called into question. Douglas Bodero (1999) has identified four major theological extremist areas. These four groups are apocalyptic cults, Black Hebrew Israelism, the Christian Identity movements, and white supremacy religions. Doomsday cults believe that they must take offensive action in order to b ring about the end of the world (White:2002). These beliefsform the basis and justification for the use of violent methods which are often directed at the United States. â€Å"†¦ (T)errorist weapons are increasingly sophisticated and deadly. † (White: 2002). Osama bin Laden excluded, intelligence agencies in the United States have been highly successful in locating and identifying terrorist group leaders. Unfortunately, the failure to obtain intelligence from Middle East sources before terrorist acts occur has often been a challenge for the United States military and law enforcement agencies.This -1- is demonstrated by the failure to win battles in the Vietnam, Korean, and Iraq Wars. While the United States certainly has a tremendous military advantage with highly technological weapons, including nuclear weapons and satellite surveillance, access to nuclear weapons has no advantage unless the United States is willing to use such weaponry. Treaties with the United Nations have outlawed the use of nuclear weapons by any country. By doing, the United States has no ability to use such military might.In the countries previously described, ground war tactics and guerrilla warfare have proved a match with American troops (White:2002). The unpopularity of the military draft, which originated in the Vietnam era, has prevented the United States from building sufficient troops needed in fighting terrorism and state-sponsored terrorism. Clearly, the United States simply has insufficient troops to battle terrorism occurring abroad. An increasing trend comes in the form of state-sponsored terrorism. Libya, Syria,and Iran are but some of the many countries which finance and provide weaponry and safe havens to terrorist groups. In the past, terrorist training camps located in Afghanistan have assisted in training aspiring terrorists from all over the world, including the Palestinian Liberation Organization (PLO) (White:2002). In order to make a dent in preventing terrorism, the United States must recognize that a policy which publicly states that â€Å"We will not negotiate with terrorists† is often an impossibility. Certainly, the British initially believed that rogue colonies in the AmericanRevolution were terrorists and Britain used that policy to no avail. The policy which is advanced herein ignores basic crisis negotiation tactics. Just as police must negotiate with -2- kidnappers and hostages to prevent harm to citizens, it is asserted here that the major conflicts could be mitigated and prevented (to some extent), with a different ideology in dealing with the â€Å"terrorists† and terrorist groups involved in the Iraq Civil war.
