Clearpath Robotics. Robotic Utility Vehicle. Grizzly


Grizzly is the most powerful unmanned vehicle in its class. Clearpath Robotics is thrilled to unveil their newest robot, the Grizzly Robotic Utility Vehicle. Designed for the most aggressive of agriculture, mining and defense robotics research programs, Grizzly is an ATV-sized robotic platform built to perform like a tractor with the precision of an industrial robot. It can pull a plow, carry a massive 600 kg payload, and mount a wide range of standard utility vehicle accessories.


Ever wonder what would happen if you combined four 26″ all-terrain tires, a solid steel chassis, 48V at 400Ah of power, front axle articulation, and a mean looking bullbar? You get a monster robot. We call it Grizzly. Grizzly is easily customizable and offers users incredible strength, an unbeatable control system, and front axle articulation that keeps the vehicle grounded and stable on even the most challenging terrain. In combining power and precision, Grizzly defines a new category of robotics, the Robotic Utility Vehicle (RUV). With 26” all-terrain tires, 400Ah power capacity, four high-power motors, front axle articulation and a maximum drawbar of almost 1700lbf, Grizzly has a likeness of a tractor. Combine those features with high precision wheel encoders, onboard current and voltage sensors, IMU, GPS, and any other sensors you could ask for, and you have a precision machine made to do the heavy work.

With Grizzly charging onto the market less than six months after the newly redesigned Kingfisher Unmanned Surface Vessel, CEO Matt Rendall commented on Clearpath’s aggressive release schedule. “We are never sitting idle, we’re here to create the best robots in the industry and Grizzly is the result of continuous research, innovation, design, and hard work”.

Grizzly is aptly named. This bot is equipped with an extremely powerful drivetrain which delivers a maximum drawbar pull of 6300 N (1400 lbf). It can survive the toughest tests, providing modularity while maintaining the rugged and robust design which has become a Clearpath trademark. With 26” all-terrain tires and an oscillating front axle, Grizzly can conquer large obstacles with all four wheels securely on the ground. It also offers top of the line control system performance. Independent high power DC motors with individual closed loop control give fine control even in the toughest terrain, while high resolution encoders and an array of internal sensors provide detailed feedback on the robot’s state.


All of Clearpath’s products are incredibly versatile and customizable, and Grizzly is no exception. 20 kWh of user-accessible onboard power, replaceable mounting plates, sensor masts, and many modular accessories provide ultimate flexibility in robotic deployments.


Matt Rendall explained “Grizzly was an ambitious project, but it’s the kind of machine we imagined when we set out to make robots – powerful, reliable… and something that gets people excited.”

About Clearpath Robotics

Clearpath Robotics has quickly gained international recognition as the go-to provider of rugged, user-friendly robots for rapid prototyping, as well as complicated custom robotics and automation projects. Researchers want to spend their time gathering valuable data and furthering the field of robotics, not constructing and testing a base platform. That’s where Clearpath Robotics comes in. We design and fabricate dependable robotics platforms with an eye towards both academic and industrial research and development.

Clearpath Robotics is a Canadian startup company founded in 2009 by four graduates of the University of Waterloo’s Mechatronics Engineering program. Clearpath has found early success, winning the FuEL (Future Entrepreneurial Leaders) Award, TiE Quest’s New Entrepreneur Award, the Shopify Build a Business Award, and taking first place in the 2011 CBET RISE Business Plan Competition. High profile clients such as the Department of National Defense, Canadian Space Agency, US Navy, MIT and Carnegie Mellon University are proving Clearpath really is “Your Unmanned Expert”.

Our Journey
Clearpath began as four University of Waterloo Mechatronics Engineering students trying to decrease the casualties of war. The US Army funded Intelligent Ground Vehicle Competition provided the ideal setting for initial development of a team of low-cost robots that could divide and conquer to clear minefields without risking human life.

Eventually, lack of resources forced this project to be set aside and Clearpath charted a new course. Production began on robust and reliable platforms for rapid prototyping. By providing innovators and researchers with out-of-the-box vehicles, their valuable time and budget could now be dedicated to developing new technology and accelerating the robotics industry.

As the first iterations of the Husky and Kingfisher started rolling, and swimming, off the shelves, Clearpath dove into a wide range of custom projects. From mining equipment to mobile manipulators for disaster response, and harbor surveillance to agriculture, no challenge has been too large, nor any robot wish list too small.

Now solidly entrenched in the industry, Clearpath Robotics is growing in well-oiled leaps and bounds. Clients including the Department of National Defense, Canadian Space Agency, US Navy, Google, MIT, and Carnegie Mellon University are proving that indoors or out; on land, water, or in the air; from out-of-the-box platforms to the custom project of your dreams – we are your unmanned experts.
