ABSTRACT
TherabotTM is an assistive-robotic therapy system designed
to provide support during counseling sessions and home ther-
apy practice to patients diagnosed with conditions associ-
ated with trauma. It has the form factor of a floppy-eared
dog with coloring similar to that of a beagle, and comfort-
ably fits in a person’s lap.

1. INTRODUCTION
An issue of growing concern in the United States is the
prevalence of sexual victimization and violence [1]. The fo-
cus of this research effort was the physical design of the
TherabotTM assistive-robot therapy system to provide sup-
port to victims of trauma during counseling and home ther-
apy practice. Therapists have found it helpful to provide
victims of trauma with stuffed animals not only as a means
of comfort, but also as a tool to ground the victims by giving
them an object they can hold, touch, and cuddle [2].

2. ROBOT DESIGN
Based on responses from three surveys, the robot was de-
signed to be about the size of a small pillow so as to fit
comfortably in a person’s lap. Additionally, the robot is
designed with a padded, furry covering that resembles the
fur of a stuffed animal. Some of the participants expressed
interest in a therapy robot that would be reactive to touch
like a real therapy animal. Not only does the robot have
touch sensors in its paws, head, and ears, it also has an ar-
ray of sensors along its chest and back. The robot’s torso
also contains a thermometer and barometer to determine if
the robot is being squeezed or held closely.
Above all else, TherabotTM was designed to be responsive
to user interaction. The robot’s legs have compliant joints
and the robot has an onboard IMU that allows it to detect
when it is moved. The robot has an electret microphone
in each of its ears to perform sound localization, as well as
a high-quality microphone that can be used to record au-
dio, allowing therapists to record sessions through a custom
interface.
3. DEMO
This demonstration shows the appearance and function-
ality of the TherabotTM robot using pre-programmed rou-
tines and artificial intelligence. We will display the life-like
motion of the legs, ears, tail, and head of the robot. Indi-
vidually actuated to move up and down, the legs will move
similarly to a dog shaking its paws. The ears will help dis-
play emotion by raising and lowering at their base. To help
show excitement, the tail will have the ability to wag back
and forth. Three degrees of freedom lie in the head allowing
TherabotTM to look up and down, left and right, and tilt its
head from side to side. All actuation will be in response to
external stimuli to provide a therapeutic effect and create
the appearance of a living dog.
