Ludovic Thériault
I design mechanisms for FIRST Robotics Competition robots: CAD, mechanical design and machining. Three robots designed so far, a fourth in progress, and off-season builds in between. Next stop: mechanical engineering.

From CAD to the field.
-
01Design it in CAD
Every mechanism starts as a model: ratios, centre distances, clearances. This one runs 48 teeth against 24 at 20 DP.
-
02Make the parts
Plates, spacers and shafts go from drawing to machine. Pockets take weight out without giving up stiffness.
-
03Put it together
Hex shafts, flanged bearings, spacers, standoffs. Tolerances decide whether it spins free or binds.
-
04Run it on the field
The part I enjoy most: watching a mechanism I designed perform in competition.
01 — Profile
Technology has always fascinated me: how fast it evolves, and how the impossible becomes everyday. I joined my school’s robotics concentration in 2021 to be part of building it. In FRC, I found what I enjoy most: designing mechanisms and seeing them perform on the field.
