week 3 & 4 update

Posted in The Blog on February 3, 2015 by frc3840
The update this time is for the past two weeks.
WEEK 3:  The solenoids were mounted, wired,and tubing connected to the air supply completing the  pneumatic system.  The team then started the lift design and assembly.  The lift design resembles a fork lift and after realizing that the design was overly complex, the team did some more brainstorming to come up with some ideas on how to simplify it.  The team also learned some valuable lessons when a voltage regulator was overloaded causing it to burn out.
I thought you would be interested in what this year’s cadet (8th grader) and our first girl on the team learned during week 3 in her own words.  This week we got a lot done.  We got our robot to work with the new kind of wheels.  I got to learn how to update the blog.  I learned how to work with the boys.  I learned how to make them go fast on a shopping trip.  That is how the week went for me.  🙂
WEEK 4:  During the week we problem solved the pneumatics by locating and fixing the leaks, and tested the solenoid programming.  Construction on the lift was finished, was mounted and connected to the motor.   It uses two sets of linear slides and a series of pulleys to raise in two stages.  A motor connected to a shaft winds up a rope which is fed through the pulley system.  We are now working on finalizing the gripper design and have started building the final part of our robot.
We hope to be finished building by the end of week 5 so that we can focus on driving practice and program tweaking during week 6.
The robot will be sealed up in a bag on February 17, not to be touched again until we get to competition in Duluth.  We would like to invite you all to come to the competition at the DECC February 26-28.  The best day to see the most action would be on Friday, February 27.
Thank you again for your support, the kids are working hard, learning much, and having fun at the same time.

week 2 update

Posted in The Blog on January 21, 2015 by frc3840
Hello everyone,
We have finished our second week of build and the students have been working very hard.  At this point they have most of the core operating systems finished.
This year it was decided to utilize four omni wheels on the drive train; two aiming forwards and two aiming sideways.  Omni wheels have edges lined with rollers at 90 degrees so that the wheels can roll in 4 directions.  Having two wheels aiming sideways enables the robot to be driven in any direction.  With this system being completed, preliminary drive train testing was begun in order to work out any bugs in the system.
A good portion of the pneumatic system was installed.  This system will be used for the forklift actuator.  Next on the list is to finish the pneumatics and to start building the actuator.  A good prototype was worked on during our first week and that design will be put into use in the final actuator being built and tweaked during the next couple weeks.

Thank you to all of our current sponsors, we would not be able to provide this great educational opportunity to these kids without your help.

Here is the link to the broadcast the team watched on Kick Off.


This link is just the game animation.

We again have 5 students on the team, including our first girl. Of the 5, 1 is an 8th grader, 2 are 9th graders and the last 2 are Juniors who are also participating in PSEO Classes at Anoka Ramsey and University of Northwestern. They are all excited about the game and are working hard at building this years robot. It has been fun watching them brainstorm and prototype this past week. They already have a good start on the chassis and the electrical board.

Again, thank you for sponsoring our team and please forward this onto anyone else in your corporation that would enjoy learning about our progress.

Hello Everyone,
The past month we have don a lot of things. We volunteered at another competition, got together, and planed for this year. At the competition we took twenty-fifth out of fifty. It was fun, and we leaned a lot this year. we are all planing on doing robotics again.

Programmer’s Life

Posted in The Blog on February 26, 2013 by team3840

Hand on the mouse, decisively clicking and dragging to make a program. The programmer’s job on a robotics team is never done. Working quickly to make a program to run a robot, the programmer must be ready to test the robot at a moment’s notice. Quietly waiting for your code to deploy, he can’t wait to see the robot move. Successfully making the robot move is the highlight of the programmer’s job.
