Total Recal - Coming to the end of week 5

We are on the eve of a deadline for some deliverables for the contest.  The website and youtube video are due on Friday.  We have drive practice at Bob Bullock State Museum on Saturday staring at 9:00 am and continuing until 3:00 pm.  

The website team was very excited with the progress they made tonight.  Jack took a computer home to continue to update and clean up the website.  He and Keren are going to meet in my classroom at 8 on Friday morning to do some final checking for grammar, punctuation, etc. 

The display team received materials from Mr. Jordan and other mentors tonight.  Linda and Rebecca worked with the display team on the breakdown of what needs to be done and accomplished over the next few days.  They have made a diorama of the display to help visualize the final product.  

The robot team worked on a variety of parts this evening.  Projects included: 

• mechanical stop for the door at the top of the left slide
• plastic cover for the microswith at the bottom
• battery mount made of lexan
• epoxied two zipties together for a more sturdy and rigid connection between the door and the pulley
• New MRT hooks were made out of 1/4" material, drilled and mounted - we discovered the Data port reader gave virtually no room for error in driving to connect to the MRT.  
• Data Port was completed and mounted but had to be remounted one inch over to allow more access for the MRT 
• Bucket was ziptied to the robot deck
• All bolts have shortened on the standoffs, motor mounts, motors and door
• Angle pieces of clear lexan were made for the MRT hooks to assist in controlling the MRT.  The black foam rubber was added to the angle pieces for additional control of the MRT. These pieces need to be slotted and mounted still.
• The MRT will set against the Data Port and be held in place with the servo hooks.   
• The arm/grabber made great progress tonight.  
• The last Igus flange bearing was mounted for the motor shaft and axle
• The motor/shaft coupler was begun.  David M worked on one with the drill press but then David W. worked on with the mill. It has been cut, and drilled for the two different shafts and set screws but needs to be tapped still
• Bucket was cut out and bent last night
• Square angle piece was mounted to the front of the arm
• Pulley was slotted for the string
• Arm was mounted on the pulley but not with the axle through the arm.  The arm sets on top of the axle.
• Servo mount tabs were cut, drilled, tapped and mounted on the arm
• Aluminum extension was cut, drilled and mounted on the servo horn with 4/40 machine screws
• The extension was bent and then taped to the bucket for demonstration.  It works but the golf ball does get stuck in the apparatus sometimes. 
• We will have to put another wooden pulley on the opposite side of the arm for balance
• Jack worked on sanding the rollers for the Omni wheel using a 4/40 machine screw, the drill press and some sandpaper.  He got two of them sanded down.  We will look at using it as a support under the bucket for when we are loaded.  This will prevent us from dumping the gadgets on the floor. 
• Jonny came by to work on programming but did not have much time since he had a concert tonight.  He did confirm that we have a dead servo.
