Product Information

The driving modes of soft manipulator are divided into cable drive, fibre-reinforced actuator, fluid-elastic pneumatic drive, variable stiffness pneumatic drive and intelligent biomimetic materials ( Lu et al., 2020). The method of cable driven is easy to implement, easy to control and can transmit power over a long distance, and the inertia is also small, so this method is used to design the soft arm in this paper. There are two commonly used cable-driven methods including 4-cable drive and 3-cable drive, both of which can realize the three-dimensional drive of the soft arm. The driving cables of the former are symmetrically distributed in the soft arm at 90°, and the driving cables of the latter are symmetrically distributed in the soft arm at 120°. Because the 4-cable drive has an extra driving cable, theoretically the bearing capacity is greater, and the control will be more accurate. However, the 4-cable drive adds a servomotor to the 3-cable drive, and an extra cable is needed in the soft arm, which takes up more space. QW coordinated the research project and conceived the presented idea. YW designed the system, implemented the analysis of the data, and wrote the paper, in collaboration with XY, BZ and JW supervised the analysis and advice. SC and AZ revised the paper. Funding

When scientists studied the octopus’s tentacle, it was found that their taper angles range from 3° to 13.5°. A soft arm with a smaller taper angle can be bent into a larger curved shape, which can grasp lightweight items with a higher curvature more easily. A soft arm with a larger taper angle has a relatively smaller degree of bending and can grasp heavier and larger items with a lower curvature more easily ( Xie et al., 2020). In the future, cameras and IMU modules could be added to the platform to realize the underwater target recognition and autonomous navigation functions of the bionic octopus robot. Then, it could be applied in more work scenarios and achieve greater value. What’s more, the robustness to impact disturbances of the robot is needed to improve. We will learn from that a new neural network enhanced control system that stabilizes a three-dimensional simulated biped model of a human wearing an exoskeleton is presented ( Liu et al., 2021). Results show that it stabilizes human/exoskeleton models and is robust to impact disturbances.

In this paper, combined with the appearance and movement characteristics of the octopus’s tentacle, a more streamlined 3-cable cable-driven soft arm is designed and fabricated, and the soft arm model is established through a data-driven modeling method. At the same time, the control method of deep reinforcement learning is extended to three-dimensional space, to realize the straight walking, left turn and right turn of the biped robot. Design and Fabrication of the Soft Arm This material was based upon the work supported by Key Projects of Science and Technology Plan of Zhejiang Province (2019C04018).

Motion Coordination and Gait Design of a Bipedal Walking Soft Robot Bio-Inspired by Octopus The Design of the Octopus-Inspired Soft Robot

First, control the servomotor to traverse the reachable space of the entire soft arm with the same interval, and use the binocular camera to capture the bending shape of the soft arm each time, and save the soft arm shape corresponding to each action. Then, extract the morphological characteristics of the soft arm, and the available image data are screened. Finally, the pulling length of the cables are used as input, and the morphological feature data of the soft arm are used as the output to train the data-driven model of the soft arm, and the simulation environment of the soft arm is obtained. When training the neural network through the random gradient descent method (SGD), a data set of images of the soft arm is constructed, and 85% of images are randomly selected as the train set of the neural network, and 15% of images are used as the test set. This method solves the problem of difficult modeling of the soft arm and establishes the multi-layer perceptron model of the soft arm through the data collected in the experiment. Because we believe in the durability of JB inflatables, we offer a 5-year warranty. The strong, high-quality and colourfast 9x9 thread PVC has several reinforced tension points and is multiply stitched, which means they are easy to keep clean. You can rest assured that you will offer a product with years of optimum playing fun. In this paper, the parameters of training are shown in Supplementary Table S2. The posture control of the soft arm is a process of continuous exploration. To improve the training effect of deep reinforcement learning, it is necessary to design an appropriate reward function ( Supplementary Table S3) to adjust the control strategy and an end sign of the current training around. When the error of the posture of the soft arm is smaller than the set threshold, or the number of steps exceeds the set maximum running times, this round will be stopped.Compared with other underwater robot, the main advantages of the robot in this paper are as follows: What’s more, another bipedal walking robot ( Portilla et al., 2019) is hydraulicly driven, and the SLIP model of land bipedal walking is extended and applied to underwater bipedal walking control. In this paper, Tanh function is selected as the activation function, the mean square error function is used as the training loss function, and Adam is used as the optimizer to train the above-mentioned deep neural network.

The structure of SILVER and SILVER2 robots is a kind of legged rigid structure which only have two degrees of freedom. Qiuxuan Wu 1,2,3* Yan Wu 1 Xiaochen Yang 1,2 Botao Zhang 1,2 Jian Wang 2,4 Sergey A Chepinskiy 4 Anton A Zhilenkov 3 We also accomplish the same experiments under the water for the movement of the space soft arm and the underwater soft arm, we pulled the drive cable with the same step to complete two sets of experiments. The experimental results show that the data-driven model is also suitable for the underwater movement of the soft arm, but the time that underwater soft arm completes the bending action is longer than the time for the space soft arm to complete the action. When the same servomotor control parameters are executed at the same time, the static bending degree of the underwater soft arm after the completion of the action is greater than the static bending degree of the space soft arm. When the drive cable is pulled with the same step, the data distribution is dense at both ends and sparse in the middle, which is synchronized with the change in the pulling length of the cable.

According to the motion characteristics of the octopus’s tentacle, a data-driven model between its parameter control and the three-dimensional posture of the soft arm is established based on the TensorFlow framework. And DQN strategy in deep reinforcement learning is used to train the model to control the actual posture of the soft arm. This modeling and control method are used in the octopus-inspired biped robot, and the walking gait of the robot is designed. By observing and analyzing multiple experiments of underwater biped walking experiments in the water tank, the rationality of the gait design of the robot is confirmed. The average speed of the bipedal octopus walking robot can achieve an average speed of 7.86cm/s when straight walking, and the maximum instantaneous speed can reach 8.5cm/s. At the same time, it can also be fast and stable when turning around.
