<p>The <b>rocker-bogie</b> system is the <a href="Suspension_(vehicle)" class="mw-redirect" title="Suspension (vehicle)">suspension</a> arrangement developed in 1988 for use in <a href="NASA" title="NASA">NASA</a>'s <a href="Mars_rover" title="Mars rover">Mars rover</a> <i><a href="Sojourner_(rover)" title="Sojourner (rover)">Sojourner</a></i>,<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> and which has since become <a href="NASA" title="NASA">NASA</a>'s favored design for rovers.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> It has been used in the 2003 <a href="Mars_Exploration_Rover" title="Mars Exploration Rover">Mars Exploration Rover</a> mission robots <i><a href="Spirit_(rover)" title="Spirit (rover)">Spirit</a></i> and <i><a href="Opportunity_(rover)" title="Opportunity (rover)">Opportunity</a></i>,<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> on the 2012 <a href="Mars_Science_Laboratory" title="Mars Science Laboratory">Mars Science Laboratory (MSL)</a> mission's rover <i><a href="Curiosity_(rover)" title="Curiosity (rover)">Curiosity</a></i>,<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> the <a href="Mars_2020" title="Mars 2020">Mars 2020</a> rover <i><a href="Perseverance_(rover)" title="Perseverance (rover)">Perseverance</a></i><sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> and <a href="ISRO" title="ISRO">ISRO</a>'s <a href="Chandrayaan-3" title="Chandrayaan-3">Chandrayaan-3</a> rover <a href="Pragyan_(Chandrayaan-3)" title="Pragyan (Chandrayaan-3)">Pragyan</a> in 2023.

</p><p>The "rocker" part of the suspension comes from the rocking aspect of the larger, body-mounted linkage on each side of the rover. These rockers are connected to each other and the vehicle chassis through a <a href="Differential_(mechanical_device)" title="Differential (mechanical device)">differential</a>. Relative to the chassis, the rockers will rotate in opposite directions to maintain approximately equal wheel contact. The chassis maintains the average pitch angle of both rockers. One end of a rocker is fitted with a drive wheel, and the other end is pivoted to the bogie.

</p><p>The "<a href="Bogie" title="Bogie">bogie</a>" part of the suspension refers to the smaller linkage that pivots to the rocker in the middle and which has a drive wheel at each end. Bogies were commonly used as load wheels in the <a href="Bogie#Tracked_vehicles" title="Bogie">tracks of army tanks</a> as idlers distributing the load over the terrain, and were also quite commonly used in <a href="Semi-trailer" title="Semi-trailer">trailers</a> of <a href="Semi-trailer_truck" title="Semi-trailer truck">semi-trailer trucks</a>. Both tanks and semi-trailers now prefer <a href="Trailing_arm_suspension" class="mw-redirect" title="Trailing arm suspension">trailing arm suspensions</a>.

</p><p>On the <i>Sojourner</i> rover the front wheels attach to the bogies, while on the MER and MSL rovers the front wheels attach to the rockers.

<p>The rocker-bogie design is <a href="Spring_(device)" title="Spring (device)">unsprung</a> and uses split rather than full-width <a href="Axle" title="Axle">axles</a>, allowing the rover to climb over obstacles (such as rocks) that are up to twice the wheel's diameter in size while keeping all six wheels on the ground.<sup id="cite_ref-Reina_8-0" class="reference"><a href="#cite_note-Reina-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> As with any suspension system, the tilt stability is limited by the height of the center of gravity. Systems using springs tend to tip more easily as the loaded side yields. Based on the center of mass, the <i><a href="Curiosity_(rover)" title="Curiosity (rover)">Curiosity</a></i> rover of the <a href="Mars_Science_Laboratory" title="Mars Science Laboratory">Mars Science Laboratory</a> mission can withstand a tilt of at least 45 degrees in any direction without overturning, but automatic sensors limit the rover from exceeding 30 degree tilts.<sup id="cite_ref-DESCANSO_9-0" class="reference"><a href="#cite_note-DESCANSO-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup>

The system is designed to be used at slow speed of around 10 centimetres per second (3.9 in/s) so as to minimize dynamic shocks and consequential damage to the vehicle when surmounting sizable obstacles.

</p><p>The <a href="Jet_Propulsion_Laboratory" title="Jet Propulsion Laboratory">Jet Propulsion Laboratory</a> states that this rocker bogie system reduces the motion of the main MER vehicle body by half compared to other suspension systems. Each of the <i>Curiosity</i> rover's six wheels has an independent <a href="Electric_motor" title="Electric motor">motor</a>.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> The two front and two rear wheels have individual steering motors which allow the vehicle to turn in place. Each wheel also has <a href="Grouser" title="Grouser">grousers</a>, providing grip for climbing in soft sand and scrambling over rocks.<sup id="cite_ref-11" class="reference"><a href="#cite_note-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> The maximum speed of the robots operated in this way is limited to eliminate as many dynamic effects as possible so that the motors can be geared down, thus enabling each wheel to individually lift a large portion of the entire vehicle's mass.

</p><p>In order to go over a vertical obstacle face, the front wheels are forced against the obstacle by the center and rear wheels. The rotation of the front wheel then lifts the front of the vehicle up and over the obstacle. The middle wheel is then pressed against the obstacle by the rear wheels and pulled against the obstacle by the front until it is lifted up and over. Finally, the rear wheel is pulled over the obstacle by the front two wheels. During each wheel's traversal of the obstacle, forward progress of the vehicle is slowed or completely halted. This is not an issue for the operational speeds at which these vehicles have been operated to date.

</p><p>One of the future applications of rovers will be to assist <a href="Astronaut" title="Astronaut">astronauts</a> during surface operations. To be a useful assistant, the rover will need to be able to move at least as fast as human walking speed. Other missions which have been proposed, such as the Sun-Synchronous Lunar Polar Rover, require even greater speeds (4–10 km/h).
