Hardware update

Hardware modifications:

  • RPS QR code has been punted
  • Most sensors have been removed
  • Servo and Igwan’s are all that remains on chassis

Remote Control

  • The remote control has been designed
  • The robot moves with XBee wireless signal
  • The robot has become sentient and drives between the elevators doors in a suicidal rage, but the doors did not close
  • I made the robot watch all seasons of American Idol
  • The robot has dissolved into fine particles because of the pain and
  • The robot has erased itself from all of time. All that remains is our memories and this website

We survived

The date is Monday the 18th. 9 days after the final competition. The dust has finally settled and to our dismay, few survived. With blood, sweat, and tears, we crawled out at the bottom of the top. With a near perfect run on our final stretch, we collected our primary points and left with our heads up high. Corrigans Cick-ass Crew shown bright than any other class that day. It was a hard fought battle for all.

Hardware modifications

All of the aforementioned changes were made between 3/26/16 and 3/31/16

Chassis:

  • Side extensions were made to the triangle rear ramp. This allowed the supplies to fall correctly and consistently.
  • Hot glue was add to the forward stern of the robot. This allowed it to not slide near the top and bottom of the extension ramp.

Drivetrain

  • The wheel and axles and gears were disassembled and cleaned.
  • Rubber bands were added to the wheel for superior traction.

Wiring

  • The wires were relabeled for better visibility.
  • Connection broke on the CdS cell. This connection was re-soldered.

Arm

  • The front plate that contacts the fuel button was enlarged and covered with hot glue for better traction.
  • Wedges were added on the left side of the arm to catch the toggle switches in case of mistake.
  • Extensions were made to the primary teeth to catch the toggle switches.

Today Was a Good Day

After countless hours of testing, our robot can complete a perfect run without fail.

We are ready for Individual Competition.

Routine Maintence

Arm:

  • Servo motor is working correctly
  • Wiring is correct
  • Magnets were hot glued to the arm and secured with tape
  • Noted that it is easy to take off the arm, but it must be put on in the correct orientation. We should find some way to ensure that the arm is always replaced correctly
  • Also, the motor should be connected to the wood mount although that is not a problem at the moment.

Sensors:

  • The left bump sensors was replaced and mounted with hot glue.
  • The left bump sensor was rewired.
  • New solder was bought for the rewiring of sensors
  • The right bump sensor was secured with an extra layer of hot glue in key areas.
  • The CdS cell was reattached to wire after falling off on Wednesday. The wires on the CdS cell had the wrong sized shrink wrap, and it was replaced with the correct shrink wrap.
  • The hot glue used was yellow. I did not like this and asked for another glue gun. The salesperson refused. I fear complications in the future involving the staff denying my a cure to my OCD.
  • Kevin Witt’s laugh is unique and a gift from the heavens.
  • The optosensors and the shaft encoders are in working order.

Chassis:

  • Braces were added to the sides of the chassis with hot glue so the robot will not get caught on the ramp

Drivetrain:

  • Gears were tightened
  • Thank Xeno for PID

 

Robot Bumpers for the Fuel Button

IMG_0689

Ain’t she a beaut?

This is what me and many other onlookers thought and said as the fuel button mechanism was completed. The robot’s size remains smaller than the limit. The wooden side plate with the extrusions were attached via hot glue cannon after a small section of the chassis was cut to the said plate.

It should be noted that the wheel mounts have been recalled and will be disassembled and returned promptly.

 

Future work:

  • Return and replace the wheel mounts
  • Purchase new set screws for the gears
  • Purchase wood needed for the main arm
  • Purchase the servo motor and the servo connector needed for the main arm
  • Plan the construction of the new arm
  • Test the robot for the 2nd performance test on Friday, March 4.
  • Document the creative process of myself as I transform the world of robotics
  • Code the robot to complete tasks.
  • Profit

Performance Test 1

We did our performance test 1 on Feb 24th. We were able exceed 100% by completing it a class early. We however failed to read the fuel light on an official test even though we know EVERYONE saw the robot complete it multiple times.

Upon completion, we received this Gorgeous certificate pictured below:

As you can see, our team is very much appreciated.

We also received the coveted “Finish Flag” for being the first team to complete PT1. Courtesy of Micheal.

Team E9 continues to dominate the competition.

 

Robot Drive Train Construction!

Cbja8-aVAAAytG- Cbja89SUAAAC29q

Today, 2/18/16 the drive-train was constructed. The team has named the robot Calvin Coolidge, not in reference to the president. We have stuck with our sponsor deal with Scott Traditions (TM). Scott Traditions, the best mandatory place to eat on north! The IGWAN mounts had to be cut slightly in order to fit under the chassis. Special wood screws were bought from a shady Ace Hardware on High St. The gentleman who sold the screws may or may not have been a ghost who has latched onto the spirit of our robot.

Construction thus far:

  • Chassis frame was cut out from 12 by 12 piece of wood
  • A front, top portion was added to the chassis to hold and support the future 2 front bump switches
  • Mount were fabricated multiple times to hold axles in place. (Hint: Use wood screws to connect an object to the another with out a bolt).
  • The axles, wheels, and gear assembly were constructed.
  • The IGWAN motors and mounts were bolted to the board after slightly altering the mounts.
  • A base for the skids was created out of scrap wood and hot glued to the chassis.
  • Spoons were added as skids. (Spoons  provided by Traditions at Scott (TM). Scott Traditions, the best mandatory place to eat on north!
  • VelCro was added such that the Proteus attaches to the top of the chassis.

Plans for near future construction:

  • 3D print an assembly for the CdS cell.
  • Attach the CdS cell with filter and light blocking assembly.
  • Wire the motors and sensors to the Proteus.
  • Fix skids
  • Add bump switches.
  • Propose line following ideas.
  • Program the robot.
