Sensors & Payload

Designed to be lightweight, simple and effective.

Camera/LiDAR & GPS/INS

Our system uses two sets of sensor systems, resulting in high-fidelity obstacle detection, target acquisition, navigation and positioning.

  1. A computer vision system conducts object detection and ranging using a Livox HAP LiDAR and the visual feed from a 120° HDR Camera.
  2. A GPS/INS system reports velocity, orientation and location.

PAYLOAD SYSTEMS:

Ball Launcher

Upgraded from a previous year's design to be more reliable while halving its mass. Rather than relying on an air pump and tank, this air cannon uses CO2 cartridges to launch supply drops safely and with reduced complexity.


The barrel for Mini-Minion’s CO2 ball launcher system is 3D-printed from PETG material. A three-barreled design was chosen to accommodate the number of targets specified for Task 4 in the RoboBoat Competition.

Inside the barrel, the racquetballs remain pinned in place by a static nub until ejected from the cannon.

Water Cannon

The water cannon achieves a high pressure, steady flow discharge using our custom-designed modular nozzles. By 3D printing initial iterations, we were able to determine the optimum nozzle shape and size through testing. The components of the water cannon system remain simple and lightweight while achieving task requirements of the water supply drop task .
