“…9–11 The rotation of the wheel and extension of the limbs are decoupled movements, so it is not necessary that both motors work when the wheel is in the circular form. 16 In addition, by using two actuators it is possible to control the leg extension while the wheel is spinning, this is not possible with wheels that have only one actuator. 8 The actuators are placed into the chassis of the vehicle.…”

In this paper, the kinematic analysis of a series of variable geometry legged wheels is presented. These mechanisms can transform a circular wheel into a hybrid legged wheel in order to combine the efficiency and ability to traverse difficult terrain of each method of locomotion. The inverse and direct kinematic problems of position and velocity are stated and solved. Then, a singularity analysis of the mechanisms is performed. The geometrical conditions that make the Jacobian matrices of the wheels singular are determined and interpreted. Subsequently, an exploration of the workspace is presented to show kinematic features of the wheels inside their operation region.

“…There is a nonconstant transmission between the knee joint and the parallel spring. It creates an effective prismatic spring between the foot and the hip with constant stiffness, resembling the spring linear inverted pendulum (SLIP) model [38]. The strategy to design Phides' running is based on swing-leg retraction (SLR) [39].…”

“…The optimized Rocker‐Bogie mechanism (D. Kim et al, 2012) uses the front bogie lifting the front wheels to achieve the stair height. TurboQuad (Lin et al, 2017), Turbo‐Leg compound robot (Zhou et al, 2019), LDR (Bai et al, 2018), and Turbo‐Leg robot (Ning et al, 2017; Sun et al, 2017) use linkages to turn wheels into legs to climb steps or stairs. The parallel robot designed by Li et al (2018) connected the wheels through the bars into a closed loop, which “multi‐wheel‐bar connection” fragments step‐climbing motion into simple repetitive action.…”

This paper proposes the mechanical design and wheel-leg-body cooperation control of a robot capable of climbing stairs for the RoboMaster competition. The robot is comprised of a robot body and four legs with wheels on each end. The front and hind legs composed of the linkages and sliders complete the climbing stairs motion under the coordination of the motors and the cylinders. The dynamic stair-climbing motion is realized by control the wheel speed and leg motion corresponding to the body motion of the robot relative to the stair environment. Compared with the common split stair climbing designed, the robot can dynamically climb the stairs without losing the forward speed, which makes climbing stairs more smoothly while retaining the ability to move on the flat. Experimental results demonstrate that the robot can climb stairs with a riser height up to 20 cm and a tread depth more than 80 cm. And the process of climbing each stair is reduced to 1-2 s.
