Cricket
is an autonomous robot that walks around by moving all six legs
using three motors. He avoids objects when touched by the feelers,
chirps randomly, and blinks his lights. After touching an obstacle
he makes various sounds depending on which feeler sensed the object.
All his functions are under control of the on board Stamp II controller.
Cricket is designed to be made from readily available materials.
The body is made of Lexan used in glass window replacement. The
legs are made from aluminum tubing, a rubber grommet, a hinged
standoff, and some plastic wire cover. Brain power comes from
a Parallax Stamp II module which can be re-programmed by the user.
A infrared sensor enables Cricket to respond to commands from
a Sony remote control which overrides his autonomous behavior.
Pushing the remote control buttons 0 - 9 causes Cricket to make
various sounds and other buttons can steer his direction and actions.
Power comes from nickel-cadmium batteries mounted inside his battery
pack but he can also run from AA batteries.
Plexi
is constructed using a plexiglass display dome for his top and
heat bent plexiglass for the tubular body. All other parts are
simple flat cut pieces. He uses a New Micros 68HC11 single board
computer running BASIC11. 18 Infrared and switch bump sensors
allow him to navigate around a room without bumping into things.
A home brew closed loop motor control system allows accurate distance
and turning motions. An RS-485 network of STAMPs and PICs provide
extra functions such as LCD display, sound, and status modules.
The motor gearboxes came from a child's motorized vehicle and
battery power is a 12V 6ah gell cell battery. Plexi has simple
maze navigation abilities and random wander routines. He also
reacts to his environment using his sound and display abilities.

BucketBot
The
BucketBot is a small PC based robot built for vision research purposes.
The robot includes a CCD camera, USB Digitizer, Pentium based biscuit
board CPU, and two differential motors. The BucketBot only uses
its single vision sensor to sense the environment. No encoders,
IR distance sensors, etc were used to test if vision can be used
for multiple situations. The BucketBot has successfully accomplished
various tasks such as line following and object tracking.
"Ebot"
is a project of the Robotics Society of Southern California.
The objective is to provide a set of instructions to build a basic
amateur robot. The instructions are intended to be detailed
enough to allow even an inexperienced person to succeed.
The goal of the project is to provide a fast route for our members
to build an operating robot.
The goal is to provide a discussion
of the design decisions that go into designing a robot like Ebot
and to provide a specific design that the members can build to;
as well as enough information that the members can modify the
design if they wish.
