Meeting of 8-16

Scissor Lift Bot:
Tonight, we mainly focused on getting the spatula to pick up and deliver sacks to the tray.
So far, the spatula has no problem picking up the sacks, but, the delivery is somewhat of an issue. It will be resolved the next time we get a chance to work on it. (Most likely not this Saturday)

The spatula is being powered by a 1:5 ratio using 2 269 motors. 

For the next meeting, we plan on trimming the top of the spatula arm and adding something in the front of the base to prevent sacks from entering the base.

Spatula Bot:

The robot itself did not receive much mechanical work. The main focus was on programming autonomous. The students working on this bot also added a limit switch that will trigger when it reaches the underside of the trough. Unfortunately, there were no videos taken.

Meeting of 8-11

Today, my mentor, Ryan, and I worked on a scissor lift concept.
Each side of the lift is powered by a high strength 2-wire motor. The motor drives a 12-tooth gear into a stationary 60-tooth gear.
Atop the lift is a tray comprised of tread. This tray will have sacks put onto it by a spatula.

After we finished building the lift, we tested to see how many sacks it could handle lifting:

(5 sacks)

(10 sacks)

`(15 sacks)

(20 sacks)

Please note that this is just a build concept, not the final design. There is still much mechanical work to be done so stay posted.
