Is this DEWBOT IX?? Will we give up pivot drive for legs? Where do the bumpers attach?

2TrainRobotics Engineering Mentor:
From what I remember, [my] frisbee launcher [senior project in college] was consistent to within +- 3 inches at 30 feet distance between 3 and 10 feet off the ground (when shot from around 3 feet). We used an 11 inch wheel connected to a CIM motor that was spinning at 1000 rpm, and we'd put in a new frisbee in each time it was back up at 1000, which was within 2-3 seconds. The keys were putting a groove into the spinning wheel to grab the frisbee, covering the wheel with rubber foam, and then having a rigid outside wall with a straight path at the end, so that the frisbee would go straight when it left the launcher.


Pancake Breakfast

Our AppleBee's Pancake Breakfast on 21-October-2012 raised nearly $1,000 for the team.

DAR FLL Tune-up

The team hosted its first FIRST event, an FLL tune-up, on 3-November-2012 at Downingtown Middle School.

Downingtown Area Robotics-Penn FLL Qualifying Event - 8-December-2012

Downingtown's first annual FIRST LEGO League Qualifying Event was held on 8 December, 2012 at Downingtown Middle School in Downingtown, PA. This competition was hosted by Downingtown Area Robotics to allow area FLL teams to compete and qualify for the Penn FLL Championship in this year's game, Senior Solutions!

Move to Oscar Way - 21-29 December 2012

After 16 months, we bid a fond farewell to 427 Creamery Way with many thanks to Waterloo Gardens for the use of this property.
We've moved to 122 Oscar Way, Chester Springs, PA (Eagle), very generously provided by Eagle Nurseries.
These moves are definitely not getting any easier with time.


FRC 1640 mentors support MOE at Fundraiser - 1-December-2012

Ben and Ellen Kellom, Clem & Faith McKown, Mike Rizzo and Siri Maley showed their support for FRC Team 365 at their annual wine tasting fundraiser.

Joe Morganto and Clem McKown visit Team 3123 - 15-Dec

Kevin Constable FRC Team 3123 Head Mentor
Joe Morganto organized a meeting with FRC Team 3123 WildCogs on 15-December-2012, also attended by Clem McKown. The meeting was set up with the purposes of learning from each other, understanding each others capabilities and how we may help each other, and to establish a basis for collaboration.
As a next step, we will hold a strategy review between the two teams at the end of the first week of build season. We'll be looking for point for cooperative and complimentary design and/or tactics.



We're in the process of selecting a new logo and motto, among other items, to unite around a stronger team brand. We're keeping our name and colors (and our award-winning performance, of course!) to stay recognizable.

Shop Organization

Okay. Shop organization has not hitherto been a strong suit for Team 1640. But things change. We spent far too much time looking for things last year.

Wheel Friction Coefficients

FRC 1640 has had a drive-train mathematical model since 2008. Wheel-to-floor friction coefficient is (not surprisingly) an important variable in this model. We've also got a pivot drive-train which provides both agility with traction and enables the use of high traction wheels without sacrificing agility. So friction coefficients are important to us and can provide a competitive advantage (with pivot). But we haven't measured friction coefficients since 2009 (Lunacy). With a new range of wheel options available, it was time to generate this important data.

6WD Testbed

We built a 6WD chassis as a testbed and a OPFOR robot. Why? Because:

  • pivot's not always the answer and we need to keep our eyes & minds open;
  • You can't be too rich, too thin, or have too many robot testbeds;
  • Our last/only 6WD robot was DEWBOT V (2009) and we've lost all driver-relevant institutional knowledge concerning 6WD drive-trains;
  • Most of our allies and opponents will be using 6WD (or 8WD,...);
  • Our drivers should know how 6WD robots drive; and
  • How to work with or against them in competition.


Skill-set (discipline) Qualifications

Skill-set, or discipline training and qualifications exist for the purpose of developing skills and knowledge within a specific arena (or discipline). Qualified students are better able to contribute to the robot's design and construction. By the way, you'll likely find these skills useful more generally than just to build DEWBOT IX. Students are allowed and encouraged to qualify in more than one Discipline. Discipline qualifications are mentor-driven, but highly-qualified students may lead training.


Team Sab-BOT-age is what it is only due to the efforts of the people involved. DEWBOT VIII's success will be in the hands of the students, mentors and parents engaged. The team's very existence is possible only through the gracious generosity of our sponsors.
