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
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 solid core copper wire

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
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
