ROBOTS -- START YOUR ENGINES!



INTRODUCTION:

The purpose of this website is to provide technical advice/resources for Electrical Engineering students at Texas Tech who are working on Mobile Robot or related projects in the EE Design Labs. This site is currently in its infant stage, but will be further expanded and improved as time goes on. The intent is that eventually many EE faculty and students will make contributions/corrections to the contents of this site.

A primary goal of this website, which differentiates it from many others, is to promote practical advice about areas such as circuit construction, wiring techniques, component selection, sensor techniques/algorithms, batteries etc.. In the near future, it is expected that many active links to related web pages will be added to this site.

HELP ME GROW

We eagerly invite faculty and students to contribute to this site. Please feel free to contribute ideas, designs, PCB layouts for common components, references to useful sensor/control components, or any other information that will enhance the usefulness of this website. Please direct inquiries, comments or suggestions to:

    Miscellaneous

    Need Scientific Graph Paper? The following adobe acrobat files can be printed using Acrobat Reader. Included are simple unadorned linear, semilog, loglog and polar plot forms. These were originally created by D. J. Mehrl using Post Script code, so there should not be any "copyright" issues associated with use of these forms, as long as you do not distribute any of this material to others and do not use it in any way for financial gain!
  • Linear Plot Form (Engineering Paper)
  • Polar Plot Form
  • Polar-Log Plot Form
  • Semi Log Form
  • Log Log Form (for Bode Plots)
