Technical Specifications
POWERBOT is
an amazing high-payload high-speed highly maneuverable platform with
all the intelligence of our smaller platforms. PowerBot moves up to 6 kph with
a payload up to 100kg. It is built on the
same core
client-server model as all MobileRobots robots, making
it software compatible. PowerBot offers a full-sized PC computer
option, opening the way for onboard vision processing, Ethernet-based
communications, laser, DGPS, and other autonomous functions. The
PowerBot stores up to 2100 watt-hours of rechargable
batteries. Fourteen forward and 14 rear sonar sense obstacles from 15
cm to 7 m. PowerBot's powerful motors and two monster
wheels on steel frame with suspension is designed for higher speeds
with
good response. The PowerBot uses 500 tick motor encoders.
Its
sensing extends far beyond the ordinary with laser-based navigation
options,
DGPS, bumpers, 6 dof DC arm, vision, and a rapidly growing suite of
other
options.
The
bare PowerBot base with included ARIA software has the
ability to:
- WANDER
randomly, avoiding obstacles
- DRIVE
controlled by keys or joystick
- COMMUNICATE
SENSOR & CONTROL INFORMATION including sonar, motor
encoder, motor controls, user I/O, and battery charge data
- RUN
C/C++ PROGRAMS created with or without ARIA or our other software
development environments
- SIMULATE
BEHAVIORS OFFLINE with the simulator that accompanies each
development environment
With
our Laser Mapping and Navigation option, PowerBot can:
- MAP
rooms, labs or buildings in minutes
- PLAN
PATHS to goals
- AVOID
OBSTACLES along the way
- NAVIGATE
TIGHT SPACES for delivery or docking
PowerBot is
designed for laboratory, commercial and research use:
- handling
- delivery
- mapping
- navigation
- monitoring
- reconnaissance
- vision
- cooperation
- and other behaviors
PowerBot
runs on floor and paved surfaces and ADA-compliant 15% grade
ramps.

TECHNICAL SPECIFICATIONS
The
powerful PowerBot 85cm x 62.5cm x 43cm
aluminum body over a steel
frame. Its inflatable 25cm dia tires handle indoors, outdoors and in
between. The two motors contain 500-tick encoders. This differential
drive platform is nearly
holonomic. Moving wheels on one side only, it forms a circle of
54cm radius.
PowerBot can climb a 15% grade and sills of 3cm. On flat
surfaces, PowerBot can
move at speeds of 6kph. At slower speeds on flat terrains, it can carry
payloads greater than 100 kg. Payloads include all accessories and must
be balanced appropriately for effective operation of this or any robot.
PowerBot can operate approximately 2.5 hours on two fully
charged batteries. Re-charging time is 5 hours.
PowerBot has a side access door. Inside is an 32-bit
RISC-based controller, sonar boards and other electronics. Each robot
has 28
sonar and two 500-tick motor encoders.
A
small proprietary ARCOS transfers sonar readings, motor encoder
information
and other I/O via packets to the PC client and returns control
commands.
Users can run the robot from the client or design their own programs
under
Debian Linux or under WIN2000 using their favorite C/C++ compiler. Our
ARIA and
other robotics development environments supply library functions to
handle
navigation, path planning and many other robotic tasks.
