A line follower

Xem 1-20 trên 123 kết quả A line follower
  • What is a line follower? Line follower is a machine that can follow a path. The path can be visible like a black line on a white surface (or vice-versa) or it can be invisible like a magnetic field. Why build a line follower? Sensing a line and maneuvering the robot to stay on course, while constantly correcting wrong moves using feedback mechanism forms a simple yet effective closed loop system.

  • This practical has been established to provide the microcontroller course at the Vienna University of Technology with an autonomous robot. The robot should be programmed by students participating in this course. The goal of this practical is to develop a working prototype suitable for teaching purposes. Line following is the ability of an autonomous robot to follow a line marked along the floor. This primary objective should be accomplished in the least amount of time.

  • Without a consistent focus on simple, fundamental prospecting and sales activities, any program or cultural change initiative is bound to fail. More than any program workbook, seminar or delivery method, it is the ongoing follow-up, the personal coaching and the manager’s ongoing support that will largely determine the ultimate success of any sales culture transformation and sales training initiative. This has proven to be the winning formula for achieving sustainable results for banks. Now let me explain how we deliver this proven formula. ...

  • In this paper I will show that it is relatively consistent with the usual axioms of mathematics (ZFC) together with a strong form of the axiom of infinity (the existence of a supercompact cardinal) that the class of uncountable linear orders has a five element basis. In fact such a basis follows from the Proper Forcing Axiom, a strong form of the Baire Category Theorem. The elements ∗ are X, ω1 , ω1 , C, C ∗ where X is any suborder of the reals of cardinality ℵ1 and C is any Countryman line. This confirms a longstanding conjecture...

  • Near-Surface Geochemistry – Near-surface geochemistry methods can be used to detect shortterm rapid loss or long-term intermittent leakage of CO2 from GS formations. These techniques are routinely employed in the environmental consulting industry and include monitoring soil gas and shallow groundwater. In general, both consist of purging the monitoring point and collecting a sample, followed by analysis and interpretation. Soil gas can be collected with sorbents, sample tubes, or Tedlar bags, depending on the compounds expected and the detection level.

  • In following the hero of this story through the last Afghan war, you will be improving your acquaintance with a country which is of supreme importance to the British Empire and, at the same time, be able to trace the operations by which Lord Roberts made his great reputation as a general, and a leader of men. Afghanistan stands as a line between the two great empires of England and Russia; and is likely, sooner or later, to become the scene of a tremendous struggle between these nations. Happily, at the present time the Afghans are on our side. It is true that we have...

  • In this volume I present some examples of line integrals, cf. also Calculus 2b, Functions of Several Variables. Since my aim also has been to demonstrate some solution strategy I have as far as possible structured the examples according to the following form A Awareness, i.e. a short description of what is the problem. D Decision, i.e. a reflection over what should be done with the problem. I Implementation, i.e. where all the calculations are made. C Control, i.e. a test of the result. This is an ideal form of a general procedure of solution.

  • For centuries the human race has noted and recorded for the following purposes: memory; communication; problem solving and analysis; creative thinking; and summarisation, etc. The techniques that have been used to do this include sentences, lists, lines, words, analysis, logic, linearity, numbers, and monotonic (one colour) usage. Good though some of these systems seemed, they have all used what you know to be the dominantly 'left cortical' thought modalities.

  • The passive components used in electronic circuits all make use of one or more of the three fundamental phenomena of resistance, capacitance and inductance. Some components depend for their operation on the interaction between one of these electrical properties and a mechanical property, e.g. crystals used as frequency standards, piezo-electric sounders, etc. The following sections look at components particularly in the light of their suitability for use at RFs, and at how they can be inter-connected for various purposes....

  • Sectoral differences in core business activities and risk exposures are well reflected in the balance sheets typical of firms within each sector. In order to illustrate such differences, stylised balance sheets for institutions from each sector are presented in Annex 2 of the report for explanatory purposes. These stylised balance sheets suggest the following broad patterns. The majority of a bank’s assets typically consist of loans and other credit exposures, while the majority of liabilities consist of deposits payable on demand and other short-term liabilities.
