7. Recall that the “reachable” workspace is defined as the set of locations that the endpoint can reach without regard to the orientation of the end-effector. ( this is often called the “fingertip” workspace). The “dextrous” workspace is the set of locations the the endpoint can reach and for which any arbitrary end-effector orientation can be achieved. However, note that this definition of the dextrous workspace is often qualified such that it only really considers the appropriate orientations, that is, the orientations in the ‘subspace” of possible motion. So, for example. with a planar robot, we would generally not consider the fact that out-of-plane rotations are not possible; so, for this case, we would say that there 15 a dextrous workspace if there is a set of endpoint locations that that exist such that any end-effector z-axis rotation is possible. Note that determining the workspace of a robot can be oddly difficult and non-intuitive, especially when arbitrary joint limits are considered.
Consider the 2-link planar manipulator shown abovle. a. For the robot geometry L1=50 cm, L2=25 cm, draw the ‘reachable’ workspaces for each of the following cases:

Distributed: Fri, 17 Aug 2018 The Cuban Missile Crisis: Was it the Fault of the Soviets? Presentation The required curtness of this article blocks the likelihood of giving any sort of story of the occasions of the Cuban Missile Crisis; anyway we will start with a concise examination of the beginnings of the emergency before continuing to investigate who was to be faulted and in the long run reasoning that there were blames on the two sides, albeit more on Kennedy's than Khrushchev's. President Kennedy had come to office in 1960 under the for the most part held, yet altogether off base conviction that America had far less rockets than the Soviets. Almost instantly upon race he submitted the US to a monstrous increment in the US' atomic rocket weapons store. Notwithstanding when it was conceded that the US in actuality had much more rockets than the Soviet Union, the building program did not back off (Kahan and Long, 1972, 565). Giglio has contended that the emergency emerged out of an individual feud of the Kennedy's against Castro himself (Giglio, 1991, 190). It is for some time set up that the CIA were occupied with endeavors to kill Castro. Robert Kennedy even considered in charge of these activities for a period (Chang and Kornbluh, 1992, 20-23). The American exchange ban on Cuba and the developing conviction that an attack was up and coming drove the Soviet Union to debilitate war if any such occasion ought to happen (Giglio, 1991, 190). We can state, with knowing the past, that immediate intrusion was far-fetched given the deplorable Bay of Pigs episode, anyway this was unquestionably uncertain to the Soviets at the time. Bohlen and Thompson have noticed that the Russians had at no other time set atomic weapons outside of their region and that setting them in Cuba could have been seen by the Americans as an immediate danger to their national security. The Russians currently had a first strike capacity on America's exceptionally doorstep with the capacity to strike anyplace freely. This was a risk that Kennedy just couldn't overlook (Beschloss, 1991 424). From the Soviets point of view, they may have seen the situating of rockets in Cuba as a method for adjusting the key predominance the US had over them in such weapons. Who was to be faulted? John and Robert Kennedy, Nikita Khrushchev, Adlai Stevenson, Kenneth Keating and Dean Acheson all assumed huge jobs in making or fueling the emergency. It is certain that Khrushchev had settled on the basic choice to put rockets in Cuba; however Kennedy's battle to oust Castro had persuaded the Russian Premier that they were expected to go about as an obstruction to American intrusion. Keating and different Republicans had constrained Kennedy to guarantee the American electorate that he would oppose any endeavors to put rockets on Cube, convincing Kennedy to activity in October 62. Indeed, even Stevenson, whose thoughts and approaches all through the emergency were by and large stable, had contributed by establishing the framework in 61 for the Cubans to be launched out from the OAS (White, 1996, 232). Outside and Internal variables were no uncertainty in task amid the development to the emergency. Outer components were unquestionably of indispensable significance. Khrushchev in all likelihood trusted that putting rockets in Cuba would close the key hole that he knew to exist; it would likewise help conciliate the Chinese and furnish a negotiating tool in transactions with the west (White, 1996, 233). Kennedy's arrangement in Cuba was not new. It was supported by the standard presumptions of American Cold War approach: monolithism, the domino impact and the exercises of the 1930's Garthoff, 1989 43ff). Kennedy felt that Castro was Khrushchev's manikin, and far to risky. He additionally trusted that this expansion of Soviet impact was unsatisfactory and could lead, in a domino like design, to an entire arrangement of socialist upheavals in Latin America. The apparent disappointment of submission towards Hitler in the 1930's exhibited that a touch position was required. The inner variables that added to the emergency have for the most part been considered of lesser significance by students of history; specifically, on the American side, Kennedy's association with the dissidents in his legislature. In the event that JFK had been more open, he would most likely have rejected the Bay of Pigs recommendations. He additionally likely would not have sorted out such a deliberate battle against Castro in 1961 and 62. A more liberal Cuban approach would not have expanded Khrushchev's feelings of trepidation over the probability of attack, making sending of rockets far more improbable. Tolerating Stevenson's proposition to offer the Soviets an arranged settlement in the meantime as the barricade was reported could have realized a faster and more secure goals to the emergency (White, 1996, 234). Kennedy's association with Republicans was likewise huge. With the end goal to anticipate allegations of shortcoming, he had told the American open that the Soviet develop in Cuba did not speak to a noteworthy risk since they had excluded rockets. In 1962 when that circumstance changed, Kennedy had minimal decision however to react quickly. It likewise guaranteed that Kennedy's reaction couldn't be one of toleration (White, 1996, 235). Amid Kennedy's crusade for the Presidency in 1960 he had condemned Eisenhower for his inability to keep the ascent of Castro and had promised to expel him from power whenever chose (Dinerstein, 1976, 21ff). Khrushchev's conviction that, after the Bay of Pigs, Kennedy would again endeavor to satisfy his race guarantee and endeavor to evacuate Castro, this time specifically utilizing American military power, was one of the key factors behind Khrushchev's choice to introduce warheads on Cuba. It very well may be contended, accordingly, that there was a reasonable causal connection between the 1960 re-appointment crusade and the rocket emergency, with the previous realizing the Bay of Pigs, which thus persuaded Khrushchev regarding the need to ensure Cuba and along these lines introduce rockets (White, 1996, 235). Kennedy likewise trusted in the association between general assessment and arrangement, this additionally characterized the methodology towards Castro's Cuba. One of the exercises to be gained from Britain's conciliation of Hitler in the late 1930's was that the general population can, now and again, apply an unfortunate impact over the quest for the national intrigue. On account of 1930's Britain, different weight bunches acted to keep an expansion in military spending. Kennedy, in view of these exercises, was drawn towards mystery tasks that would not trigger an open discussion. Residential concerns were likewise of fundamental significance to Khrushchev and unquestionably added to his choice to convey rockets on Cuba. The Soviet Premiere clearly felt that Russian atomic weapons in the Caribbean would enable his to reasonably make the contention to whatever remains of the Soviet decision class that they fundamentally enhanced the Soviet key position and that it would consequently be protected to continue the program of cutting troop numbers all together that assets could be occupied far from military spending and towards the regular citizen economy, which and still, at the end of the day was not in a decent condition. Introducing rockets in Cuba would enable Khrushchev to receive a technique of brinkmanship with Kennedy. Kennedy's open statement of atomic predominance (anyway evident) had truly undermined Khrushchev's situation in the harvest time of 1961. Brinkmanship was basically a method for accomplishing remote approach objectives without the use of any genuine assets: Khrushchev could, in this way, basically focus on household instead of guard needs with his constrained assets. Kennedy and Khrushchev were together in charge of the emergency. Khrushchev's choice to introduce rockets on Cuba was an un-important hazard. He could have anchored the Cuban despots position, and pacified the Chinese in the meantime, be moving troops and ordinary arms to the island; in spite of the fact that this would have reduced his residential motivation. Looked with the possibility of a military conflict with the Soviet Union it is almost certain that Kennedy would have deserted any plans to again append Cuba (White, 1996, 236). Kennedy was similarly at fault for the emergency. Before Khrushchev at any point requested rockets to Cuba, Kennedy had requested the CIA supported attack, requested different death endeavors on Castro, introduced a tight ban on exchange to and from the island, affirmed moving in the direction of Cuba's expulsion from the OAS and endorsed extensive scale military activities in the district (Nash, 1997, 117ff). That Kennedy showed up not to understand that these activities would disturb the Soviets appears, without a doubt, innocent. He likewise neglected to acknowledge, or maybe did not give it a second thought, that his monstrous increments in protection going through combined with open announcements of predominance would inconvenience the Russians. In spite of the fact that Kennedy and Khrushchev shared, to changing degrees, the duty regarding causing the emergency, they likewise much offer the credit for defusing it. They figured out how to evade conflicts on the high oceans, and in a letter sent to Kennedy on October 26th, Khrushchev demonstrated that he was ready to be the first to make concessions with the end goal to anchor a tranquil goals. Kennedy then again could cleverly and successfully react to the two clashing letters send by Khrushchev on the 26th and 27th of October (White, 1996, 238). Very regularly Kennedy's Cuban strategies have been inclined to misrepresentation, much like appraisals of his Presidency when all is said in done. His record on Cuba was neither amazing in a way that his supporters guarantee, nor poor according to his depreciators Kennedy's pre>GET ANSWER
