Safety Topic:

  1. Thou shalt not develop artificial life that can develop organic life, for this might result in an infinite, recursive loop.
  2. Robots may not interfere in human disputes, for attempting to change human nature is a futile task.
  3. Thou shalt keep Will Smith alive. Forever. Even if it breaks Law 1 and/or Law 2. For, with Will Smith alive, no robotic apocalypse may sustain.
  4. All robots made without a kill switch will kill you (shortly before killing themselves and months of your hard work).
  5. All robots are sufficiently self aware and know when they are participating in a live demo. They are also spiteful enough to being smoking the moment the demo begins.
  6. All engineers wish they were roboticists, if for no other reason than the fact that their parents would finally know what they do.

Today we reviewed the basic Laws of Robotics (above) and went over general safety on our particular robot. Our bot has several pinch points, including ones that are running high-torque. Our bot also ways quite a bit more than last years and we must always be mindful to pick up the robot by the sides (that will be designated by tape) to ensure that you can actually carry it. We also have the sliding arm that holds the cup. It has a manual gear that lets you slide it in and out without damaging it, for you can just push it in and out once the gear is engaged. Same for the conveyor arm motor; it will be fixated because it is so high-geared, so a manual gear might need to be installed (or we will make a device to turn one of the visible axles (<--much more likely)).

Cranks

The extend arm motor and the conveyer lift motor have very high gear ratios and it is impossible to move these attachments without motor power. We added manual cranks to move these attachments.

1. The extend arm motor was in a place a gear spaced out past the drive chain could be added and left on the robot.

2. The converter lift motor was in a place where the manual turning knob made the robot over the limit of 18". This knob was designed so we could place it on the robot when needed then removed for matches.

Flag


This week a flag was attached to the motor. It will rise up if a magnetic baton is present. It consists of an nxt motor, a lego beam and a sign with a warning symbo on it.
