[ ONE ROBOT - MULTIPLE APPLICATIONS ]

Agility

Due to our patented wheel frame, our mobile robots can climb 50% slopes, curbs of up to 15 cm, and perform 360° turns even on a 30° sloping surface. They are highly agile, and due to their AWD design, they can drive in all terrains from urban to rural settings, and on any surface, from pavement to mud and sand, without getting stuck.

 

Curb Climb

By the combined torque effort of both the front and rear wheel motors, our solution can efficiently traverse obstacles up to 40% of wheel height. Whether the obstacle is sharp, rounded, or one or all wheels encounter the obstacle, does not matter.

When first encountering an obstacle, our solution pulls with its front wheel and pushes with its rear wheel, effectively climbing the obstacle.       

As soon as the front wheel has traversed the obstacle, the side wheels can be pulled over the obstacle by the combined effort of the front and rear wheel, which inherently stabilizes the steering. This movement is further strengthened due to the pull angle, going from the front to the side wheels.

Once the side wheels have cleared the obstacle and gained stability, the rear wheel is pulled over the obstacle by a combination of its torque and the pulling force of the front wheel. The side wheels further strengthen the movement due to the pull angle, going from the side wheels to the back wheel.

Steering & Propulsion

Typically, mobile robots are based on either Differential steering or Ackermann steering. We have combined the two, utilizing their advantages and omitting their disadvantages.

A differential-wheeled robot varies the drive output of its two drive wheels in a differential manner to generate a curvilinear motion. This method’s drive path is unstable due to its reliance on surface friction, tire wear, and the distance between the driving wheels.

An Ackermann-wheeled robot turns the front wheels to allow it to deviate from a straight line. The point of the steering mechanism is to avoid tires slip sideways when driving in a curvilinear motion. While ensuring controllability and stability, the wheel frame suffers from low agility and high turning radius.

Our solution has steering and drive forces separated through its innovative wheel frame. This constellation makes it simpler to predict the robot’s drive path and movement becomes more energy-efficient since all available drive torque goes into propelling the robot forward. Additionally, our solution utilizes the agility from differential steering and the stability from Ackermann steering.
