![]() ![]() Wheeled robots are unique in that their stability is guaranteed by the support of the wheels in contact with the ground. The robot’s autonomous function also includes environmental sensing to create a controller that adapts to its posture and position. The robot’s locomotion system is an important factor to consider in the robot’s design, which depends on the environment and its technical parameters, such as mobility and stability. They are required for specific tasks such as environmental sensing, trajectory planning, control and obstacle avoidance. In recent years, many robots deliver packages in the market. Simulations and experimental results demonstrate the robot’s ability to respond to potential falls as it climbs and descends stairs.ĭue to the services of autonomous mobile robots, the demand for them is growing rapidly. In this way, the controllers prevent the robot from falling to restore contact between the wheels and the step. Loss of contact with the ground is a critical factor in an emergency situation where the robot’s stability is at risk. In this way, you can get information about the geometry of the terrain and detect the loss of wheel contact with the ground. We also offer an emergency controller to prevent the robot from falling while climbing up or down by measuring the contact angle of the wheel with the ground using a laser scanner sensor on each side of the robot. This paper proposes a methodology for designing a six-wheeled rover that adapts to different stairs and maintains its stability based on robot parameters, kinematic constraints, maximum height and minimum step length required for ascent and descent.
