This ready to use mobile robot platform is designed for researchers developing advanced robot appli-
cations such as remote monitoring, telepresence and autonomous navigation/patrol.
Mechanics
The X80 is the result of efforts to develop a robot that would be fast and strong, while itself remaining
lightweight and nimble. The wheel-based platform’s two 12V DC motors each supply 300 oz.-inches
of torque to the X80’s 18 cm (7 in.) wheels, yielding a top speed in excess of 1 m/s (3.3 ft/s). Two
high-resolution (1200 count per wheel cycle) quadrature encoders mounted on each wheel provide
high-precision measurement and control of wheel movement. Weighing only 3.5 kg (7.7 lb.), the
system is light, but it can carry an additional payload of 10 kg (22 lb.).
Sensors
X80 offers full WiFi (802.11b) wireless, multimedia, sensing and motion capabilities and comes with
a wide range of sensor, camera, and audio modules, sufficient to serve in any variety of applications.
The X80 offers broad expandability as well for projects that may require additional sensors, even spe-
cialized modules. Powered by separate RC servo motors, the integrated camera head can pan and
tilt independently.
Architecture
The X80’s underlying technology evolved from Dr
Robot’s Distributed Computation Robotic Architec-
ture, originally developed for Dr Robot’s Humanoid
(HR) Robot. Using this approach, high-level control
of the robot is maintained by a remote or local
PC/server communicating by a secure wireless link.
Low-level functionality is managed by an onboard
digital signal processor (DSP) while computationally
intensive operations are performed offboard. The
result is a robot that’s lighter, draws less power, runs
longer and is dramatically less expensive than a fully
bundled or self-contained system. Moreover, since
primary processing resides in a server, any hardware upgrades to the central unit are shared by all
the robots it controls.
With its integrated high bandwidth (11Mbps) WiFi 802.11 wireless module, the system can upload
all sensor data (including encoder sensor readings) to a PC or server at rates in excess of 10Hz.
Similarly, streaming audio (8Hz x 8bits) and video (up to 4 fps) either for direct monitoring or for
