Grizzly

ROBOTIC UTILITY VEHICLE

Grizzly is a large all-terrain robotic utility vehicle that offers the performance of a tractor and the precision of an industrial robot. This all-electric workhorse has a maximum continuous drawbar force of 1400 lbf and a payload capacity of 600kg.

Grizzly is built for the most demanding outdoor environments, making it ideal for mining, military and agricultural research. It interfaces with a variety of payloads, including single-point hitch implements as well as all of Clearpath’s sensing, computing and manipulator packages.

Features

TOW CAPACITY

Grizzly is an industry-leading robot workhorse.  With a maximum continuous drawbar pull of 1400 lbf, Grizzly is well equipped to tow massive payloads and industry-standard implements.  A high-torque upgrade is available for even more aggressive tow performance.

PRECISION CONTROL

Grizzly has four independently driven wheels, each with high-resolution (2500 counts per revolution) encoders and finely tuned closed-loop control.  The result is precise linear position control even at low speeds.

PASSIVE SUSPENSION

Grizzly employs a passive suspension system to traverse challenging terrain while always maintaining 4-wheel ground contact and traction.  With passive 16-degree front axle articulation, Grizzly can easily overcome positive and negative obstacles.

POWER PACKED

Grizzly comes standard with a 200 Ah, 48V sealed lead acid battery pack.  An onboard 5V, 12V, 24V and 48V, independently fused user power interface can easily supply large power-hungry payloads like manipulators and agricultural implements for hours.  A generator upgrade can be added for more demanding needs.

COMPATIBLE IMPLEMENTS

With a detachable front bullbar, and a single-point Class 1 hitch at the rear, Grizzly is factory compatible with a wide range of standard utility vehicle and tractor implements.  It also has a modular interface for connecting with a wide range of more high-tech robot accessories.
