The primary structural framework of Trundle is made
from 3/16” aluminum panels and 1/8” stainless steel rods. Steel
counterweights are used for balance.
Trundle senses the world through an array of distance
sensors. These sensors allow it to recognize the proximity of nearby
people and objects. A pyroelectric sensor tuned to the temperature
of the human body is currently being added to allow Trundle to detect
Trundle currently has two degrees of freedom. Its
two cascading servo motors each have a range of movement from 0
to 180 degrees giving it a wide range of motion. A third motor is
currently being added to the top to provide lateral movement.
