The rocker-bogie system is the suspension arrangement developed in 1988 for use in NASA's Mars rover Sojourner, [1] [2] [3] and which has since become NASA's favored design for rovers. [4] It has been used in the 2003 Mars Exploration Rover mission robots Spirit and Opportunity, [5] on the 2012 Mars Science Laboratory (MSL) mission's rover ...
The rocker-bogie system is a suspension arrangement, in which there are some trailing arms fitted with some idler wheels. Due to articulation between the driving section and the followers, this suspension is very flexible.

Some mechanisms that produce reciprocating, or repeating, motion are designed to produce symmetrical motion. That is, the forward stroke of the machine moves at the same pace as the return stroke. These mechanisms, which are often referred to as in-line design, usually do work in both directions, as they exert the same force in both directions. [6]
An articulated bogie (aka Jakob-type) is any one of a number of bogie designs that reduce weight, increase passenger comfort, and allow railway equipment to safely turn sharp corners, while reducing or eliminating the "screeching" normally associated with metal wheels rounding a bend in the rails. There are a number of such designs, and the ...
In the physical science of dynamics, rigid-body dynamics studies the movement of systems of interconnected bodies under the action of external forces.The assumption that the bodies are rigid (i.e. they do not deform under the action of applied forces) simplifies analysis, by reducing the parameters that describe the configuration of the system to the translation and rotation of reference ...
A classical hunting oscillation is a swaying motion of a railway vehicle (often called truck hunting or bogie hunting) caused by the coning action on which the directional stability of an adhesion railway depends. It arises from the interaction of adhesion forces and inertial forces.
In the USSR, per GOST 2582-72 with class N insulation, the maximum temperatures allowed for DC motors were 160 °C for the armature, 180 °C for the stator, and 105 °C for the collector. [13] The one-hour rating is typically about 10% higher than the continuous rating and is limited by the temperature rise in the motor.
