Gear ratio selection is typically based upon theoretical top speeds or pushing power, but oftentimes, this isn't the criterion, and is a poor model for actual events. Sprint distance can play a much bigger factor for agile defense.
In this, we'll take a look at how to optimize based on reaching a certain point first, rather than being as "fast" as possible.
Following in the footsteps of many other spreadsheets, this presents the motor curves with an analysis of the electrical series resistance of the 2014 Control System.
This short paper describes the mechanical design of Cyber Blue’s 2014 “winch” to play the Aerial Assist game. We are publishing this paper in an effort to help teams that may be struggling with this part of their robot design.
Cyber Blue completed acceleration and top speed testing on 3 gearbox reduction ratios to determine and compare the acceleration rates and top speed using each. Gearbox ratios of 5.3:1, 6.0:1 and 7.0:1 were used.
The quickest way to select a VEX gear ratio. This workbook quickly determines the best 1 or 2 stage VEX gear box needed to reach the desired gear ratio.
This presentation introduces the concepts needed to effectively manipulate objects. It discusses various object considerations as well as various lifting techniques.
This presentation gives an overview of the various types of bases used in competitive robotics. It covers stability, center of gravity, drive train configurations, and system requirements
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.
