Electrical Wiring Concept
• PC104 standard technology is designed for limited space applications – Compact (3.6 x 3.8 in)
– Rugged and reliable connectors– Low power consumption (1-2watts per module)
• PC104 enclosure is designed for hostile and mobile environments• Shielded wiring will be used to prevent coupling of electrical noise• Connection terminals will have locking mechanism to improve robustness• Kill switch is used in case of an emergency

RIT
Power Board Concept
• Motor modules will be self-regulated• The power distribution board will provide 5V and 12V to the PC104 stack• Features:
• Over current protection to onboard electronics• Voltage surge protection• Provide regulated aux outputs ( two 12Vdc and two 5Vdc line)• Its scalable by ‘stacking’ additional power boards

Bill of Materials
• Budget Risks– Mitigation: Use RIT resources and order
Samples to avoid purchasing minor components such as fasteners & resistors
![Page 14: R I T Advisors: Dr. Wayne WalterMechanical Engineering Dept. Faculty Jeffrey WebbTeacher’s Assistant Team Members: Aman Verma EE - Electrical Craftsman.](https://reader036.fdocuments.in/reader036/viewer/2022062516/56649d4e5503460f94a2e940/html5/thumbnails/14.jpg)
RIT
Risk Assessment• Motor Module (P07202) Requirements
• Current 45A w/spikes up to 82A• Heat 300F
– Mitigation: Use heavy-duty wiring Design frame and Thermal Analysis
• Test on Tube Inserts, Bolts and Connectors– Mitigation:
Impact analysis Vibration analysis
• Center of Gravity– Mitigation:
Payload constraints implemented Turning radius and speed of the platform restricted.
• Non-deliverable Power Board of the Motor Controller team (P07302)– Mitigation:
Use RP-100 Power Board to provide regulated voltage.
• Batteries• Budget• Battery Life
– Mitigation: Negotiate with P07202 Motor Module team Battery Life monitored by battery indicators.
• Kill Switch Design and Capability– Mitigation:
Standard red mushroom-shape Placed between the two 12 Volt Batteries connected in series
