bdpa it showcase: 'robotics: scara, cartesian and the elephant man' (briana lee)
DESCRIPTION
Briana Lee is a junior at Columbus South High School. She was a first-time participant in the 10th annual BDPA IT Showcase held August 1-2, 2012 in Baltimore, MD. Briana wants to attend college and become licensed as a psychologist. Her BDPA IT Showcase research topic was, ‘Robotics: SCARA, Cartesian and the Elephant Man’. Ms. Lee shared in her research information on how robotics plays such a huge role in the technology world. She discussed the history, components, barriers and impact of robotics on our society. She compared SCARA, Cartesian and the Elephant Man robotics prototypes and demonstrated how they were each being used in everyday life to make businesses more efficient. Ms. Lee is another example of the young people that receive powerful STEM experiences as a result of the work of BDPA on a local, regional and national level. Ms. Lee is the ‘future face of technology’ and she is yet another reason for you to invest in BDPA!TRANSCRIPT

Cartesian & The Elephant
Man Created by: Briana Lee
History of the Cartesian
A Cartesian (Answers, 2012) coordinate robot (also called linear robot) is an industrial robot. It has three principal axes of control are linear which means they move in a straight line rather than rotate and are at right angles to each other. Cartesian coordinate robots with the horizontal member supported at both ends are sometimes called Gantry robots. They are often quite large.
SCARA
The SCARA acronym stands for Selective Compliant Assembly Robot Arm or Selective Compliant Articulated Robot Arm.
SCARA's are generally faster and cleaner than comparable Cartesian systems.
History of the Elephant Man
Science of robotics (eHow, 2012) only came in the 20th century; the human-invention of automation has a much lengthier past. Robotics in the 20th and 21st centuries has advanced radically to include machines capable of assembling other machines and even robots that can be mistaken for human beings.
SCARA, Cartesian & Elephant Man
Help businesses more efficient.
More profit
Less hard work
Workers not excepting the machines
Economics
Not understanding how to use the technology
Its arm was rigid in the Z-axis and pliable in the XY-axes, which allowed it to adapt to holes in the XY-axes. By virtue of the SCARA's parallel-axis joint layout, the arm is slightly compliant in the X-Y direction but rigid in the ‘Z’ direction.
SCARA
It has four joints that are connected together
It has a base
X-axis help to move it in a horizontal direction
Y-axis helps it to move in a vertical direction
Z-axis helps it to rotate in a circular motion to the right or left
Brake-release button also located at top to facilitate manual teaching of points
Alarm LED lights located on the top face of the robot for clear and immediate indication of any problems
Controller for exceptionally
easy programming, calibration and troubleshooting
Absolute encoders
How does SCARA work?
SCARA robot system for mechanical assembly, material handling, packaging, machine tending, screw driving, and other applications that require fast and precise automation.
How is SCARA used? SCARA robotic arms function much in
the same way as a human arm would and can even simulate certain elbow functions. Most notable is the fact that SCARA robots are speedy and sturdy equipment. They provide optimum performance in activities that require precise movements and tasks where speed and repetition are critical. Other applications for SCARA robotic arms are: - Stacking and de-stacking - Dispensing - Welding
There are also space issues associated with the SCARA robot. They are tall equipment so they require a lot of vertical
Impact of SCARA
Industrial robots improve productivity at pet food plant. The SCARA robots (Tm Robots, 2012) are a part of production lines that manufactures birdseed sticks that are embedded with nuts.
SCARA robots make the best use of the available work area.
Barriers
Updating and maintenance cost
Not keeping up with the advances in the technologies
Difficulty in using
Difficulty in developing technologies
Technology not being accepted by workers
Investments are at high risk
Finding firms that are willing to invest in these technologies
Robot being incompatible with the existing practices and current construction operations
Get economical support to afford the expensive parts that it takes to make the SCARA
Educate the workers and the companies that
having a SCARA in the business will help the
business efficiently, more profit and less hard working
Start with small, fast projects that enhance learning of the technology
Future use of the technology
To be put in manufacturers to make things easy.
To help manufacturers save space, increase output and reduce costs
Traditionally SCARAs have only been used on end of line packing, in sealing, labeling and packaging, but not in picking up product in primary packaging or food manufacture.
