An overview of Stomatobot V0, my ant-weight combat robot prototype inspired by mantis shrimp (stomatopods). The prototype served as a proof of concept and will advance development of future versions. The robot was designed, built, and driven by me, Corbin Grubb.

1. Stomatobot V0
Ant-Weight Combat Robot
Designed, built, and driven by Corbin Grubb,
As a part of the WPI Robotics Club

2. Inspired by Mantis Shrimp
(Stomatopods), Stomatobot V0
served as a functional prototype
for future ant-weight combat
robots.
Stomatobot V0 featured six
klann mechanism legs, and a
hard shell supported by stiff
plastic springs.
An asymmetrical vertical spinner
was used for the active weapon.

3. For using legs instead of wheels,
the bot was granted a weight
limit of two pounds, twice the
limit for wheeled bots.
All parts for Stomatobot V0 were
printed, with screws, bearings,
and electronics as exceptions.
The bot used a 3-cell LiPo
battery, two brushed drive
motors, and a brushless weapon
motor, with a receiver and two
ESCs to control the bot.

4. As an experimental prototype,
Stomatobot V0 only won one of
its five fights, but sustained little
damage.
The fights proved the resilience
of the shell, but the bot lacked
maneuverability.
Several design changes are
being implemented in
Stomatobot V1, as well as a
“Club” weapon.
