Tasks This Meeting: 

Work on wiring, work on robot body in CAD, build multiplexer in CAD, connect sensors to prototype board.

Reflections For This Meeting: 

Soldering takes forever, and we've decided that Al is our new wiring guy. But, thats o.k, because he is really good at it.

 Our biggest goal this meeting is to get all the prototype board sensors mounted and wired to the prototype board. This includes soldering and connecting. AL is also going to focus on making the wiring harness for the servors on the hand, and feeding those all the way back to the servo controller. It would be really cool if we could get the robot 'legs' on by the end of the meeting too - as Alice looks a bit odd without her legs attached.

Picture of the flat 'cut out' CAD drawing for the prototype board housing that Karl designed on his own yesterday. He cut it out of PETG and  used the torch to bend into shape. 

 

The prototype board housing built using the CAD template, now in place with the prototype board in place and secure.

Al attached the chain for the motors to drive the wheels on the left side, and Karl doing the same on the right side.

Al worked on wiring the servo wires for the hammers to lower the bridge, and bringing the wires up to their end point.

Al continuing to wire the servo wires and preparing to attach the robot's legs and wire that together.

I spent a lot of time crimping the wire connectors onto the potentiometer wires for the prototype board.  For those wires, we are using connectors that go on the ends of the wires, so instead of having to solder all the wires onto the board, they can just be pushed onto the prototype board header connectors.

Me and Al working on getting the various wires into place.

Here I am stripping the wires to crimp the connectors into place.

Here I am connecting wires to the potentiometer from the prototype board.

... and soldering the wires into place on the potentiometer that measures the arm's movement.
