Teams that are consistently designing and end up with weight problems need to look at their design process and make corrections in "Weight Management". - Mike Martus [more]
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.
Our ME redesigned a gearbox using the Fisher-Price gears, but removing the final stage to increase the speed.
We're using these on a ball conveyor and a ball collecting beater bar.
This paper details the development process of a gearbox for the Gearheads 2009 robot in dirty iterative detail. It also serves as a mechanism to capture team intellectual property.
This paper covers how to interface FIRST legal motors (the Chiaphua, Fisher Price, and Globe motor) to the commercial off the shelf Dewalt XRP 3-speed transmission. It includes detailed instructions, pictures, drawings, costs and a good source to get a small amount of machine work done. This lightwe...
Attached is the complete design for the Killer Bees' 2004 Four Speed transmission design. Included are a full set of detail drawings, part CAD files, assembly files, a technical writeup and supporting engineering data. All design work was done in Autodesk Inventor.
Unfortunately, the files gener...
This report details the design, construction and performance of (team 188) Woburn Robotics' 2004 drivetrain. It featured six driving motors (Bosch, CIM and Fisher-Price) and a two-speed transmission (using pneumatically actuated shifting dogs). The robot, Blizzard 5, was capable of a top speed of a...
This is a conceptual single speed gearbox design from team 179 (Dan Quiggle). It combines the CIM, Drill and FP motors. The intent was to minimize fabrication and cost. I'm posting it for some professional feedback, but also to inspire teams to consider making their own vs. buying pre-made gearbox...
Description:
The Who'sCTEKS present their 2004 Dual Speed Dual Motor Gearbox. This design is a refinement of their 2003 Dual Speed run during the 2003 off-season. It uses the CIM and Bosch Motors and can be built as a single motor gearbox.
Enclosed are our updated designs for a dual-motor, dual-speed robot transmission system, as developed by Team Epsilon Delta (Team 116). After examining a few successful gear-shifting transmission designs during the 2002 FIRST Robotics Competition, we decided to implement this capability for our robo...
