An illustrated example willbe given to demonstrate the development of the proposed algorithm through a simple two-dimensional manipulator.I. IntroductionThe continuously increasing demands for enhanced productivity and improved precision haveimposed special requirements on the control of industrial robots and caused a shift of emphasistowards the dynamic behavior of manipulators. This shift has led to the development of model-based control algorithms, which incorporate the dynamic model of the manipulator in the controllaw in order to decouple the robot joints. The underlying principle is to: (1) design a nonlinearfeedback algorithm that

The ensuing impromptu laboratory experienceconvinced me that every student in the class reacted strongly to exploding components.Thereafter, my basic electronics lab could look forward to destroying/exploding the “Componentof the Week” each Monday. The students utilize a programmable power supply to set up theexplosive conditions. To get different results, the students can program a step function for aquick explosion or a slowly varying ramp to slow-cook the component. The more smoke, themore enjoyable.

The configuration is done prior to running a simulation of this modulation type. The configuration fileonly has to be written once for multiple simulations of the same modulation type.

IntroductionThe use of Internet and studio classrooms is an emerging trend for promoting “individualdiscovery” as a strategy for enhancing engineering education. Here we describe how thesetechniques can be combined with traditional laboratory exercises to create a suitable environmentfor interactive, on-line operation of lab experiments over the Internet, to be used either in theclassroom, in a studio setting, or from a remote location as part of a distance learning strategy.1Central issues in creating a user-friendly and efficient technology for interactive, on

everything so nothing your accomplish getsforgotten. Tie your two roles together. And remember that neither time “in rank” or childhoodlasts forever.I. IntroductionThis paper was prompted by a section of the book, Ms. Mentor’s Impeccable Advice for Womenin Academia by Emily Tooth1. Ms. Mentor received an inquiry about balancing familyresponsibilities with academic career. She titled her reply “A Wife or a Life?” Her basicpremise was that it was practically impossible to be an involved mother and wife with asuccessful tenure career. We believe women faculty can find balance between their many roles,but must be given the freedom to so.We are 1) a single mom and 2) a working mom with the perfect husband (he cooks, he cleans, hespends his vacation days

(2) Students have almost an unlimited amount of time. (3) Each student can obtain help from a variety of sources.Eliminate any one of them and the workshops lose much of their effec-tiveness. The unlimited amount of time is particularly powerful because itallows the instructors to guide the students without telling them the specificsteps to solving a given problem. Instead, one can review generalities, walka student through simpler analogous problems, and ask leading questions.A student eventually learns how to solve the problem, but does

It is always desired to force the magnitude curve’s slope at crossover tobe –1 (log-log plot) or –20db per decade (semi-log plot). This will yield a stable system with a phasemargin between 0 and 90 degrees which depends on the length of the –1 segment. The ideal situation forthe shape of the phase curve is shown in Fig. 1. The peak of the phase curve occurs at wc thus yieldingthe maximum phase margin and creating a system that is robust to plant variations. A given phase margin(PM) specification will determine the length of the –1 slope segment.A more important specification to the user after stability is assured is system

Much of the studio session centers on a set of modules that we havedeveloped locally for use in our undergraduate and graduate heat transfer courses. Whileit would probably be possible to take the next step and teach this entire course in the“studio” mode, as has been done in many courses at RPI and several other universities [1-4], we have not taken so drastic a step as yet.
