Abstract: An assembly for a wheel of a robotic vehicle and a method for overcoming an obstacle for said robotic vehicle. The assembly comprises a first arm portion and a second arm portion, the first arm portion being attachable to a chassis of the robotic vehicle at an attachment point and extending forwardly and downwardly relative to the attachment point in a direction of a movement of the robotic vehicle. The second arm portion is pivotably connected with the first arm portion at an arm pivot point and extends forwardly relative to the arm pivot point in the direction of the movement. The wheel is rotatably mounted on one end of the second arm portion opposed to the arm pivot point. A wheel rotation axis being positioned at least as high as the arm pivot point relative to a surface on which the robotic vehicle is positioned.

Abstract: Method of operating a lid of a robotic vehicle. The lid is operable by a motor between an opened and a closed positions. When the lid is between the opened position and a first intermediary position, a first electric current having a first value is provided to the motor for exerting a first force on the lid. When the lid is between the first intermediary position and a second intermediary position, a second electric current, having a second value whose sign is opposite to a sign of the first value, is provided to the motor for exerting a second force on the lid. The second force is applied in an opposite direction of the first force. When the lid is between the second intermediary position and the closed position, a third electric current having a third value having a same sign than the first value is provided to the motor.
