Provisional Pivot Drive Chassis Drawings - 1-January-2010 - Clem
A body of Drawings have been created using AutoDesk Inventor based upon a provisional Pivot Drive design. pdf versions of these drawings are provided below.
- Chassis (mk VI r4) Drawings - Basic Chassis Drawings
- Pivot Fabricated Parts - Fabricated Parts required for the Pivot Wheel Assemblies
- Pivot Assembly - Pivot Assembly Drawings
- Frame Weldment Drawings - Chassis Frame weldment drawings including all weldment parts
- Frame Welding Template Drawing - Welding Template for the Chassis Frame & Chassis Frame Form
- Pivot Plate Drawings - Pivot Plate drawings
- Chassis Frame Form - The Chassis Frame Form is a substitute chassis which enables the parallel scoring systems development and construction (on this Chassis Frame Form) while drive software, tactics and skills are developed using the actual chassis. The Chassis Frame Form is a workflow tool.
In addition, there are a couple useful excel worksheets
BUMP traverse analysis & Proposed Drive-train/Chassis - 13-January-2010 - Clem
Read Over the Hump, an analysis of a proposed Drive-train / Chassis (4-wheel Pivot Drive with 4" wheels and 28" wheelbase) traversing Breakaway's BUMP.
On Monday, 11-Jan, we decided on:
- Using 4wd
- Pivot is our 1st choice in drive-train. If this is impractical, we would use Mecanum drive or would fix the Pivots and drive as a Tank.
- Robot frame needs to avoid ball entrapment
- We want to be able to go over bumps and through the tunnel
- We want to hang from the tower. If we need to decide between hanging and going through the tunnel, we'll select hanging.
- In Autonomous, we should
- Score 1 ball if in the alliance zone & clear the goal area
- Score or move-to-alliance-zone 2 balls if in Mid Field
- Move 3 balls to Alliance Zone or Mid Field if in Opposing Field
- We could have a Herder/Pusher and a Kicker. Maybe on opposite ends (or not)
- We need to begin prototyping Kickers / Herders / Pushers
- Need a Chassis / Drive-train design fast.
- First field element priority of the BUMP. Second is GOAL & VISION TARGET. Then TUNNEL & TOWER.
My stream-of-conciousness first-thought slides on Breakaway and DEWBOT VI are posted here.
2010 Kit of Parts Motor Curves available (xls format).
Drawings Posted - 17-January-2010 - Clem
Fabricated Pivot Parts drawings are available. These take into account both the experience with the prototype and the requirements of Breakaway.

Crossing the Bump - 5-February-2010 - Clem
Running the Bump - An analysis of DEWBOT VI climbing the bump in "Landscape" (y) orientation, then pivoting wheels to drive along the bump in "Portrait" (x) direction. This doesn't work.
Over the Hump (reprise) - An updated analysis of DEWBOT VI crossing the bump in "portrait" (x) direction. This analysis includes the current design's Center-of-Mass.
