The Michigan Daily Vol. XCII, Ann Arbor Michigan--Saturday, July 17. 1982 Ten Cents Twelve Pages student's robot Computers meet robots in unique student-built robotic system By SCOTT STUCKAL It's small, shiny, has one mechanical arm, and. is made by University students. Brave new world come to campus? Not exac- tly, but it is one of the first student-built robotic manufacturing systems in the country. The system was assembled as a project of Prof. Yorem Koren's Mechanical Engineering 483 class. THE CLASS normally builds individual machine parts using a computer-controlled cut- ting tool, but last year Karen decided that students should use the parts to build a robot. "Instead of just making parts that nobody needs, why not go on to a project and try to make IT'S NOT A new type of weapon. It's the manipulator arm of a. a practical robot system?" Koren said. computer-controlled robotic system built by students in Prof. The class designed parts for the robot Yorem Koren's computer control of manufacturing class. manufactured it, and assembled it in the course Polish heads quit in part shake up of several terms. The robot, which has a mechanical arm known as a manuipulator, is then connected to a computer that controls its actions. Students said they enjoyed the oppor- tunity to build, rather than merely study an ac- tual robotics device. "WE WERE enthusiastic about the robot in the sense that it was practical," said engineering graduate student Jerry Raski. Mechanical engineering student Jim Randolph said that when he learned a computer-controlled robot would be constructed in the class, he decided"this is the one (project) I want to do. Robotics is pretty much an up-and-coming field." Koren said a major problem with current robotics instruction offered at the University and across the See STUDENTS, Page 5 WARSAW, Poland (AP)- Several prominent Communist Party officials quit yesterday in a major leadership shuffle that appeared to strengthen martial-law chief Gen. Wojciech Jaruzelski's grip on power. Leaders also expanded the party's top ranks. The changes in the Politburo, the policy-making Central Committee and the Secretariat, which administers the party apparatus, were the most sweeping since martial law was im- posed Dec. 13 to crush the independent Solidarity trade union movement AMONG THE resignations reported by the official PAP news agency was that of Stefan Olszowski, a hardliner who in the past had been considered a major contender for party leadership. Olszowski, who was responsible for ideology and the news media, resigned from the Secretariat but kept his Polit- buro post, PAP said. The unexpected resignations of Olszowski, another Central Committee secretary, Hieronym Kubiak, and Politburo member Jan Labecki came at the end of a two-day meeting of the 194-member Central Committee on the problems of youth. THE LEADERSHIP changes recalled the turbulent party meetings last year during the labor crisis sparked by the birth of the now-suspended Solidarity union during shipyard strikes in Gdan- sk in August 1980. Among those who rose to power during the period were Labecki, Com- munist Party chief in the Gdansk shipyards, and Kubiak, a liberal from Krakow who ran the cultural and scien- tific apparatus. PAP said Kubiak retained his post on the Politburo. A fourth Central Committee secretary to resign, Marian Wozniak, was made a full member of the Polit- buro, as was Stanislaw Kalkus, a newcomer who is a foreman in the Cegielski Works in Poznan. THE ADDITION of Wozniak, elected Warsaw party chief last month, and the election of Gdansk party chief Stanislaw Bejger as an alternate mem- ber of the Politburo appeared to strengthen Jaruzelski's hand, obser- vers said. Bejger was named Gdansk party chief in January, replacing liberal Tadeusz Fiszbach who had been closely identified with Solidarity. Although little is known about Kalkus, he appears to have been elec- ted in response to demands of workers of the Cegielski Works who objected to the removal of the Poznan party chief earlier this year.
