1 IGVC Power Team (BZZZZT!) Presentation October 17 th Electrical Engineering Senior Projects 1 Nate – Jake – Tim

2 Concept Design 2 ft 3 ft

3 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 Requirements Based 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, W max output, 60 lb, 2.5+ hour run time at 25 Amp Load Gas generator (DC output) – Coleman Sport 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 VTC – 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 ~ 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

8 Fuel Cell Pictures

9 Electric Motors Currently unknown as to the specifications Expecting about 350~420 W motor requirements – $44 for 24 volt 350 W Mechanical Engineering team will help supply specs – 2~3 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.
