5. ARGOS Operator Training
Trained as an ARGOS
operator
Supported two days per week
Supported for R2 and SAFER
testing
Setup
Follow documented procedure
for proper startup
Different payloads
Operate
Maintain vigilance on the
control system and the payload
Shutdown
Follow documented procedure
for proper shutdown

6. 6
Video Wall consists of 6 video
towers
Power distribution design for
towers
Selected parts from given
requirements
Collaborated with:
Larry Dungan, Electrical Engineer
Frank Delgado, Project
Manager/Software Designer
Bryan Griffith, Mechanical Engineer
Video Wall Project

7. 7
Only custom electrical design is the power
distribution
Other connections are computers and monitors
Utilize 3-phase 208VAC
Allows three 120VAC single-phase
Adequate 208VAC is available in the facility for 2
video walls in support of initial deployment
Minimizes electrical cables from video wall to
facility
UPSs were used for power conditioning
Also provides power backup due to 208VAC
power sags in Building 9
Equal distribution of loads across available power
Power Distribution

Power Distribution
•Break down
of power on
three
breakers
•Breaker
selection
based on
data is 20A
•Wire size per
National
Electric Code
is 12AWG

Goal:
Build, program, and demonstrate a working service
type robot
Future usage in a new ER5 education outreach program
Used VEX robotics kit to design service bot
Tested different software to program the robot
Programmed bot with RobotC software
Demonstrated service bot to Office of Education at JSC
Service Robot Project

12. Software: RobotC
Advantages
Simple Visual
Programming
Language (VPL) blocks
Generates C code
from the VPL blocks
of code
Drag and drop
features all C code
generation
Real-time debugging
features
Multiple programs in
one slot of robot
brain
Disadvantages
Some code writing
experience is needed
