Manipulator

Notes: 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
