### device | mechanism | robot:

Fractal robot
* are collections of cubic robots of different sizes that move under computer control.
* can avoid unnecessary removal of material.
* have many uses.
* make the entire process safer by automating the tasks and reducing human error.
* use electricity for power to move and to communicate between themselves.

Mobile robot
* All mobile robots use locomotion that generates traction, negotiates terrain and carries payload.
* can operate by remote control or autonomously.

Web robot
* Web Robots are programs that explore the web automatically
  - traverse the Web automatically

Several mechanism
* act to facilitate ketone production.
* are utilized to remove mercury from the body.
* can lead to upward flow of ions
  - result in the movement of gas from the pneumoperitoneum
* cause the dissipation of the dust disk on fairly short timescales.
* contribute to the development of an effusion.
* enable the stigma to disriminate between pollen of different types.
* exist by which concrete floors can be a major moisture source
  - for the transport of amino acids across cell membranes
* govern the pathways the axons travel.

  - and effective fire protection system known
  - used for water gardens
* can keep the dust down and keep cattle from getting sick.
* come in a variety of sizes for specific waterworks.
* have large water droplets, which wet cows to the skin for maximum evaporative cooling
  - their own beauty
* includes sections.
* often create wasteful runoff when set to water the upper slopes of hills or berms.
* placed on the end of a hose also vary greatly, with respect to how much area is covered.
* react to temperatures in individual rooms.
* rot fruit rot that occurs most commonly on pears and less commonly on apples.
* send an alarm immediately when fire is detected.
* shoot a single stream of water and rotate that stream in a circle.
* splash water from the ground and from affected plants and help spread the mildew.
* waste water.
* wet the flowers and foliage and makes the plant more susceptible to diseases.

Fire sprinkler
* Save money.
* activated by heat deliver water only onto the fire.
* are an example of loss reduction.
* can help save lives
  - save money
* conserve water and fire department resources.
* have one purpose and that is to keep any fire that starts as small as possible.
* protect lives and property.
* save lives, property, and money
  - time, property, and, most importantly, lives

Tape drive
* allow large companies as well as end users to backup large amounts of data.
* are delicate machines and develop dirt over time
  - mechanisms
