The workbook illustrates motor performance on a single graph and allows you to see where your motor is operating at. It is key to finding your optimum gear ratio to meet you system requirements.
"Techniques in Robotics Programming" presentation by Daniel Katanski (Team 240) and Steve Martin (Team 470) at the 2006 Kick-off meeting in Novi, Michigan. This session discussed a variety of software and electronics related topics which include: using the EEPROM, simple diagnostic scree...
Due to some recent confusion on how to change the channels on the OI for practice situations, I put together this quick whitepaper that hopefully explains everything.
This was posted on a technical discussion thread a while ago, but I don't know how many people saw it. We had busted a 120A Bussman circuit breaker and wanted to know both how it broke and how it worked. this is our results
This paper documents Team Ford FIRST's stand-alone IR beacon and IR sniffer. It was designed to free up the Edubot from field beacon duty, it operates from almost any supply ("wall-wart" or 12 volt battery), generates either TYPE 0 or TYPE 1 signals, or if paired with another identical ...
In 2003, Jay Tenbrink of the Martians asked me to write an article about batteries for their team. This is the article with some updates for 2004. It contains info on common problems with electrical design and discusses in depth the SLA battery used to power FIRST Robots. If you ever have questio...
Instructions for building a battery changer cabinet. Cabinets holds up to 6 batteries and chargers and has optional panel meters to monitor the health of each battery and a battery load tester.
This document contains the entire code for team #115's Global Positioning System, which uses four IR sensors mounted on servos in order to determine the robot's exact position and orientation, along with an error function which gives an estimate of the confidence in the given values. The walkthro...
This is a list of all the materials you will need to build a battery cart. Solidwork Drawings will be posted in the next few months. If you have any questions and please feel free to PM I and I will help you with anything I can. Hope every team has one of these HOT battery carts next year!!
" While initiating tests with the infrared, we realized that a 40 kHz
generator was needed to be adapted into the infrared emitters. But thinking about the adaption of this disposition on the field of tests, we felt it was necessary to develop a similar generator, ...
Attached is a File pictorial for the new Joystick.
The large center button sends different OHM values for its 5 potential positions, and it is connected to the same pin numbers as the P1_wheel was last year.
This is in answer to my question:
1) Is there any electrical information on the p...
Since a lot of people have been having difficulties with their IR sensors over on the Programming and Electrical boards, I decided to write this flowchart that helps teams find out whats wrong with their IR systems. If you're having troubles getting your IR to work with the default IR code, take a...
(Copied from a thread I created to here, so it will be easier to find in the future. Also updated the code to correct a typo in the comments that described the available variables in user_routines.c.)
I'm hoping this may be of use to some teams out there who'd like to be able to control their ne...
It is possible to gain additional resolution from an A/D converter thanks to the noise inherent in the signal. This paper explains how this happens, as well as how to use this to your advantage.
Our Northrop Robotics' Engineer and his fellow mentors are teaching this course each Sunday, open to FIRST teams.
"This document is written to accompany a course of instruction in robotics fundamentals for high school students participating in a competitive robotics team. Our intent in prepa...
