Manipulator

Banebot motors are being selected with the criteria of minimizing weight and the size of the transmission.  Sunday's model cconcept has been revised in a brainstorm by Mike and Alex. The new version has a belt tensioner. The manipulator has been fully tested and was able to scoop the tube without pushing the tube into the gripper.A concern was raised that the gripper have some sturdiness and rigidity so it doesn't flop or wiggle around.

Discussion on use of a sensor / camera - electrical suggests a banner sensor to tell if the tube was correctly positioned.Camera suggestion to use it as part of the arm to sight the tube pieces.

Deliverable  /  Receivables: Electrical - controls should spec a sensor and the mech group will make a placeholder for it.

Arm

Currently designing it to be made of 2 x 2 x  1/8" wall aluminum tube. Unpowered - both unfoldign and telescoping still on the table. Folding has a spring loaded gate latch.  Current weight estimated at 4lbs, using gravity to extend. Designing to avoid a wiggly arm.

Shoulder joint has sprocket.  Single motor planned - sensor point - perhaps a potentiometer.

Deliverable: From Larry! Drawings for the prototype going to Harris should be finished and sent out tonight.  Finish the arm to define the supporting structure.

Mini-bot

Prototype has lost a wheel and now drives with one wheel. The final geometry is defined and they are putting it into inventor.

Deployment - tonight's activity to determine the best location for deployment.  Strategy (Drive Team) is working tonight to drive an older robot to test different approaches to the pole and tower. 

Deliverable - Decision on deployment location.

Drive Train

Copper spacers and the angle brackets have been added to the design.  Angle brackets have been started in the shop. The 30 toothed sprockets did not come with the wheels from IRI, Tom C. Is investigating.

Discussion on use of encoders - with the transmissions.

Deliverables - to resolve the sprocket situation.  The team is ready to assemble the frame - the rest of the Mechanical teams are satisfied that the planned configuration of the frame will meet the needs of the arm and support.

Electrical

Mock board is ready for the drive train. 

They have been working on testing the reflective sensors on Thunderfoot to determine the best locations for functionality.

Deliverables - to advise drivetrain of the best positioning so the space can be reserved for the sensors on the drivetrain by Thursday. To get a list of sensors started.  To learn about the encoders that are with the transsmissions.

Controls

Is ready for the drive train!

Receivable -  from Drive Team - how do they want to drive the robot.

Deliverable - from Larry! Order parts by Thursday.
