Hornet 7.0

Aug 2021 – May 2022

Project: 

Hornet 7.0
The Hornet training programme is under Team Bumblebee, which is is a student-run robotics team consisting of students from Electrical and Computer Engineering, Mechanical Engineering and Computing.

Project aim:

to build a low-cost AUV to participate in the Singapore AUV Challenge (SAUVC)

Requirements of SAUVC: 
  • AUV navigation, visual identification, acoustic localization and robotic manipulation 
My team: 
  • Electrical team > Power subteam
My main role: 
  • in-charged of providing power supply to rest of the components via buck and boost converters
  • perform power balancing to equalize the voltage and state of charge among the cells 
  • designing of PCB
 
We went from this breadboard...
...to this PCB design!
AUV Specs:

SBC: Orange Pi 4
Power System: 16.8V 10000mAh LiPo Battery (x2)
Propulsion System: BlueRobotics T200 Thrusters (x6) & Arduino Nano
Sonar: Sparton PHOD-1-Hydrophon

 

Sensors:
Depth sensor: Bluerobotics Bar 30
Motion sensor: BNO085 IMU
Camera: RaspiCam V2
Communication: CAN protocol
Degrees of Freedom: 6 (Surge, Sway, Heave, Roll, Pitch, Yaw)
