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...

This zip file contains all the information about the 2002 ThunderChickens CCT. It contains a Word document describing the theory and math, an Excel document with the Bill of Materials, AutoCad 2000 drawings, a STEP solid model of the assembly, SolidWorks 2001Plus native solid models, assemblies, an...
Team 716, the Who’sCTEKs would like to share our 2002 dual motor gearbox design. The drawings are in AutoCAD R14 and are in a self extracting zip file. This shows a simple way to couple two motors using gears and sprockets. Key factors are shaft center distances and matching motor speeds.
