within 6.2 Newton Seconds or 13.2%. These results are very
impressive given the quality load cell and vehicle
manufacturing from AXFAB.
within 6.2 Newton Seconds or 13.2% of expected. Due to
multiple changes in project and scope LANDER initially chose
very cheap load cells since the test stand demonstration was
originally mean't to be a verification for much larger goals.
Acquiring usable data from the load cells ended up taking much
more time and resources than the team initially expected, but
thanks to proper risk mitigation the team was able to overcome
the challenge and find a real solution.

subsystems, Control Software, Avionics, Control Mechanisms,
Structure, and Test Stand. The test stand involves a complex
hardware in the loop computer simulation running on a
microcontroller.

As shown in the figure to the right, the TVC is the yellow
assembly mounted inside of the rectangular vehicle. The red
mounting brackets of the vehicle are screwed into the blue
load cells. The load cells are bolted to the green mounting
plate, which connects the vehicle assembly to the black test
stand.
The simulated vehicle comprises a feedback loop where the
rocket motor causing forces on load cells translates to forces
in the simulation. The control system utilizes a PID which
gives commands to the simulated vehicle; the commands are then
translated back into hardware as TVC commands. The physical
vehicle encompasses the avionics, TVC, and load cells. The
physical vehicle receives commands from the simulated vehicle
and returns, calculated thrust data back to the control
software.

<h1 class="display-4">Final Report</h1>
<p class="lead">
LANDER compiled all of the work and findings from the two
semesters spend in capstone into a single document.
At the conclusion and verification of the Operational
Demonstration LANDER has compiled a Final Report for the project.
The Final Report compiles two semesters of work into one succinct
document that highlights all of the findings from the project.
