Revision as of 01:07, 10 August 2011
In order that we continue to develop knowledge and skills, Team 1640 is again engaging in a Summer program in 2009. We will meet Tuesday evenings from 6:30 to 8:30 pm at the Downingtown Educational Center starting 23-June through 18-August. We will be meeting in the shop area.
The FRC team will be working on our summer projects to develop new knowledge through prototyping and testing.
Contents
23 June Meeting - Goal Setting
The team's missions for this summer were agreed upon:
- Prototype and test a 4-Wheel Pivot Drive chassis.
- Prototype should allow multi-mode drive:
- Tank - Tank wheels on each side are parallel
- Crab - Crab wheels pairs (front and rear) turn the same direction
- Snake - Snake wheel pairs (front and rear) turn in opposite directions
- Target a ½-scale prototype using Vex parts and follow-through with a hypothetical Autodesk Inventor chassis design in FRC-scale. (12*18" actual size)
- Prototype should allow multi-mode drive:
- Engage in a literature and paper study of arm, gripper and lift systems
In addition:
- Paul K has a Vision control mission.
- Alex H has agreed to learn Inventor.
7 July Meeting
We started building our prototype (for real) at this meeting.
Here are the drawings for fabrication & assembly (pdf format):
At this meeting we:
- Collected the parts we will need
- Identified parts (just a few) which need to be ordered
- Cut all of the metal parts which need cutting
- Started assembling the Pivot Wheel Units
14 & 15 July Meetings
Kenneth joined the team! Welcome.
By popular demand, we are meeting Tuesday and Wednesday evenings.
At these meetings we:
- Built all of the Pivot Wheels Units
- Built the basic frame
- attached the first Pivot Wheel Unit
- Performed some gearbox repair on DEWBOT V
- Replaced missing pneumatic parts from DEWBOT III
21 & 22 July Meetings
Progress:
- Installed all Pivot Wheel Units
- Installed all Pivot Wheel Steering Gears & Drives
- Installed cRIO and Digital Sidecar
- The Prototype is Mechanically Complete
28 & 29 July Meetings
We're (mostly) wired. We made something move (with a motor)!
4 & 5 August Meetings
It's programming time. 'Nuf said.
Posted 9-Aug as a programming tool for Pivot-Wheel:
- Programming a Pivot Drive Robot.
- Pivot Worksheet - based on 0-5vdc Potentiometer Output.
- Pivot Worksheet - based on 0-1024 Potentiometer Output.
11 & 12 August Meetings
Prototype drives in Automobile & Snake Modes.
Carly officially approves of Snake.
We still have some work to do to get this working correctly. Plus there's the whole issue of drive orientation.
Great progress on a technically challenging project, but work to do yet.
18 & 19 August Meetings
Paul (on vacation) & Kenneth have been working hard together on the code.
Crab Mode works. A few small quirks, but basically solid.
Kenneth updated the Automobile & Snake setpoints logic so that the pivot angles are correct (with the inside-of-turn wheels pivoting more than the outside-of turn).
Wonderful progress on a challenging project. The prototype drives beautifully.
