State of art techniques utilize active systems for stronger suction in surface crawlers while the passive approaches have limitation in providing consistent grip while moving across curved surfaces or dents. Embodiments herein provide an autonomous surface crawling robot for crawling over surfaces using electro-mechanical assembly for creating strong suction force and enabling the robot to smoothly crawl over flat surfaces, horizontal/vertical/inclined surfaces, curved surfaces, and surfaces with dents. Battery powered motors are used for only mobilization, while mechanical assembly generates suction to provide consistent grip across different type of surfaces. A dual flexible cam profile assembly including a cam profile and a guide rail generates required suction and addresses the technical challenge of maintaining suction across varying surfaces without using external power for suction generation. The dual flexible cam profile provides a robust, less prone to error or slippage type passive crawler mechanism, with consistent grip across uneven the surface.

Techniques are directed to utilizing a suspension protector to deflect debris away from a set of suspension components of a tracked vehicle. The tracked vehicle includes a vehicle body, a suspension, and a set of suspension protectors. The suspension couples with the vehicle body and is constructed and arranged to control movement of the vehicle body using tracks. Each suspension protector couples with the vehicle body and is disposed a predefined distance from a respective wheel of the suspension to deflect debris thrown from the respective wheel and a respective track away from a respective set of suspension components of the suspension.

A suspension and drive system includes front and rear torsion axle assemblies. The front torsion axle assembly includes a front axle, a front shaft, and a front arm connecting the front axle to the front shaft. The rear torsion axle assembly includes a rear axle, a rear shaft, and a rear arm connecting the rear axle to the rear shaft. A center of the front torsion axle assembly and the rear torsion axle assembly together define a quadrilateral. The front axle defines a first vertex of the quadrilateral, the front shaft defines a second vertex of the quadrilateral, the rear shaft defines a third vertex of the quadrilateral, and the rear axle defines a fourth vertex of the quadrilateral. An interior angle of the quadrilateral at the fourth vertex is less than an interior angle of the quadrilateral at the second vertex.

A self-propelled work machine, in particular a tracked vehicle, such as a bulldozer, having a traction drive comprising at least one electric motor for driving at least one chassis wheel, in particular a chain wheel or a sprocket. The motor axis of rotation of the electric motor is arranged displaced and/or angled with respect to the wheel axis of rotation of the chassis wheel to be driven by the electric motor.

Track systems for traction of a vehicle in which a spacing of laterally-adjacent ones of the track systems in a widthwise direction of the vehicle is adjustable. This may facilitate use of the vehicle in different conditions (e.g., in different field configurations, such as in different configurations of row crops, where the vehicle is an agricultural vehicle). For instance, the spacing of the laterally-adjacent ones of the track systems may be adjustable while the laterally-adjacent ones of the track systems are connected to a powertrain of the vehicle and/or without requiring use of additional parts (e.g. spacers).
