A system is provided that includes a machine assembly, a first imaging sensor, an encoder, and one or more processors. The machine assembly is movable to actuate a brake lever of a vehicle in order to open a valve of an air brake system. The first imaging sensor is positioned to acquire two-dimensional perception information of a working environment that includes the brake lever during movement of the machine assembly towards the brake lever. The encoder detects a displacement of the machine assembly relative to a reference position of the machine assembly. The one or more processors estimate a target position of the brake lever relative to the machine assembly during movement of the machine assembly based on the two-dimensional perception information and the displacement. The one or more processors drive the movement of the machine assembly towards the target position of the brake lever.

A robotic system validates brake bleeding by detecting one or more forces generated by a machine assembly acting to move a brake lever of a vehicle in order to open a valve of an air brake system of the vehicle. The system also detects displacement of the machine assembly as the machine assembly acts to move the brake lever, monitors one or more sounds generated one or more of during or after the machine assembly acts to move the brake lever, and determines that the brake lever has been moved to a position to open the valve of the air brake system to release the air brake system based on the one or more forces that are detected, the displacement that is detected, and/or the one or more sounds that are monitored.

The one or more processors detect a position of the brake lever relative to the machine assembly based on the acquired perception information and the detected displacement of the arm. The one or more processors generate a motion trajectory for the machine assembly that provides a path to the brake lever. The one or more processors drive movement of the machine assembly along the motion trajectory towards the brake lever.
