Beam Adjustment Mechanism (BAM) - functional model.

CASE SUMMARY

With an optimized budget, Newton built a functional model of BAM. This model demonstrated the mechanism's design maturity and capabilities to achieve necessary resources for remaining development.

CLIENT REQUEST

The Global Ecosystem Dynamics Investigation (GEDI) leadership team asked Newton to adapt the beam adjustment mechanism (BAM) to visually demonstrate enhanced functionality. This fully-functional model served as a demonstration for project stakeholders to approve additional funding.

The GEDI uses laser technology to deliver detailed, 3D maps of the Earth's forests. GEDI will help scientists better understand trends in climate change and land use on our planet's ecosystem.

SOLUTION

The visually appealing 1-to-1 scale functional model:

• Replicated the instrument's internal components, optics, and utility;

• Incorporated rapid prototyping, machining, and proprietary finishing techniques;

• Operated via a battery-powered electronics box with a simple user interface including a voltage meter and buttons/knobs to control mechanism operation;

• Oriented the laser successfully using a Risley prism.
