143 WHEELED ROBOTS AND LUNAR CARS 4

Epaddle robot

ePaddle robot, 2015, from China. This eccentric paddle mechanism robot uses its paddles to climb over obstacles or upstairs. Frictional requirements of the paddle-aided stair-climbing postures confirm that the robot can climb up the stairs. https://www.semanticscholar.org/paper/Modeling-paddle-aided-stair-climbing-for-a-mobile-Sun-Yang/603d0764234f5a35036dc9620f13e144a45ffc21

Transformable Wheel

Transformable wheel, 2014. Wheel transforms itself in legs with a passive process. The robot can climb over an obstacle 3.25 times as tall as its wheel radius. https://www.semanticscholar.org/paper/Wheel-Transformer-A-Wheel-Leg-Hybrid-Robot-With-Pa-Kim-Jung/e5a6182a424bddd6feb68d958bdeb056bf356913

Wheel Transformer Robot

Wheel transformer robot, 2013. The transformation process is passively operated by an external frictional force, so it does not need any actuators. https://www.semanticscholar.org/paper/Wheel-transformer-A-miniaturized-terrain-adaptive-Kim-Jung/f2bd099e3bfba150258d7bb2f2411b609fdea369

Hybrid Vehicle Unmanned, 2018

Hybrid vehicle, unmanned, 2018, entered into competition at the third land-based unmanned system competition “Crossing Obstacles 2018” at Beijing. This very interesting vehicle is fitted with 4 Tri-Star-wheels (like Terrastar in the 60s) surrounded by tracks which was never seen on an off-road vehicle. Wheels and Tri-Star wheels are mounted on 4 pendulums. This concept appears very new. Chassis is rigid. At equivalent size, is it better than an articulated tracked vehicle for crossing obstacles ?? https://www.youtube.com/watch?v=0pzkOpN0ftk

Longma Articulated 8x8 Robot unmanned

Longma Articulated 8x8 robot, unmanned. Articulated chassis with positive pitch control is not new (see Metrac of Meili 6x6, 1958) but never used for series built vehicles except Gama Goat (without hydraulics and positive pitch control) and Goer witch was an articulated  4x4 in the 60s. It was found that price was higher, load space and payload reduced. Only tracked vehicles like Volvo BV 202, Hägglünds BV 206 and now several Russian articulated tracked vehicles were or are fitted with positive pitch control. Nevertheless, this articulated 8x8 presented at “Crossing Obstacles 2018”near Beijing is new (8x8 articulated) and very exciting to enhance land mobility. It must be tested and it could be interesting if it could be series built. Land-based unmanned system competition 'Crossing Obstacles 2018' on Sep. 10, 2018 involved 136 participating teams from 61 units, including 14 military and civilian colleges and universities, 26 private companies, 10 state-owned companies, and 11 research institutes, which contains most of the elite research teams of land unmanned systems in China  near Beijing.
The competition included 10 competition events of 4 categories, such as autonomous maneuvers and reconnaissance in the field, transportation of unmanned systems. Many very new locomotion systems were presented and that's good for off-road locomotion. https://translate.google.com/translate?hl=fr&sl=auto&tl=en&u=https%3A%2F%2Fhk.on.cc%2Fcn%2Fbkn%2Fcnt%2Fnews%2F20170121%2Fbkncn-20170121094220412-0121_05011_001.html, https://www.youtube.com/watch?v=0pzkOpN0ftk

Morphable Wheels Robot, 2017

Morphable wheel robot, designed by Xu Qiwei, a second-year graduate student of SJTU-ParisTech School of Elite Engineer awarded at Shenzhen in 2017. The robot has three gestures of movement; the “round-wheel gesture” does exactly what it says, and is used for moving on smooth surfaces. The “forward-paw gesture” is used when the robot encounters obstacles when moving forward, where its wheels will morph into forward-mode paws and allows itself to climb over obstacles of certain heights. The “backward-paw gesture” is similar to the forward one, except it is used when moving backwards. The innovation here includes the design and optimization of the three-mode morphable wheels, the strategy analysis of how to cross over different types of obstacles on different surfaces.
