Areas of Improvement Over Previous Robot
Electronics

• Extend operating time
• Provide constant reliable voltage to motors and
  other electronics
• Condense power supply into a single unit
• Add the E-Stop emergency stop safety feature

4
Expected Power RequirementsBased on Previous
Robot Design

• Power draw of 960 W
• 80 A current
• 12 V motors
• Like to know power draw of GPS, LIDAR, computer
  and wireless systems for possible integration of
  power supplies

5
Power Supply Options

• Deep-cycle Battery
• Optima Blue-top Battery SC31DM
• 12 V battery, 12000 W max output, 60 lb, 2.5
  hour run time at 25 Amp Load
• Gas generator (DC output)
• Coleman Sport 1850
• 12 V DC, 180 W output, 70 lb weight
• Honda EU1000i
• 12 V DC, 100 W output, 30 lb weight

6
Step-up Converter

• Analytic Systems 12V to 24V Converter 45 Amp
• Part number VTC6051224
• May increase run time by 100
• Increase performance and reliability of motors
• Use as the power cutoff for E-Stop
• Draws approximately 60 watts of power
• Considering for experimentation

7
Fuel Cell Concept

• 1.2 KW DC output Useable Indoors and Outdoors
• Weighs 30-50 lbs
• 2.5 by 1.5 ft
• 7,000 cost
• A single 200 dollar tank could last 6 days of
  continuous use at 100 load
• Recommended DC-DC converter to smooth output and
  prevent excess power draw from motors

Electric Motors

• Currently unknown as to the specifications
• Expecting about 350420 W motor requirements
• 44 for 24 volt 350 W
• Mechanical Engineering team will help supply
  specs
• 23 motors for 4 wheel design
• 2 motors for 3 wheel design

10
E- Stop

• To meet new requirements and to improve the
  safety of the vehicle an E-Stop will be
  hard-wired into the system
• Accessible E-Stop Big Red Buttons located
• On the vehicle
• On a remote control
• May also steer the robot as an extra feature.
