Drones are perhaps the most well-known type of flying robot. They come in all shapes and sizes, from large military drones to small consumer drones.

BALLU2: A Safe and Affordable Buoyancy Assisted Biped

Jang, H. J. Training in endoscopy: Colonoscopy. Clinical endoscopy 50, 322, https://doi.org/10.5946/ce.2017.077 (2017). The hyperparameters are chosen via grid search to have the least test loss. The list of searched hyperparameters and their candidates are the number of hidden layers h l ∈ 2 0 , 2 1 , ⋯ , 2 7, hidden units h u ∈ 1,2,3,4, and the learning rate α ∈ 0.0001 , 0.0002 , 0.0005 , 0.001 , ⋯ 0.05 , 0.01. As a result, a network with three hidden layers with eight hidden units, respectively, and a learning rate of 0.002 were used.

They are a type of flying robot that uses one or more gas-filled balloons to stay afloat. Airships are made for leisure and sporting activities, but can also be used for military and commercial applications. To determine which variables should be considered in the state vector, a statistical investigation was first conducted on the extensive potential relationships between the state variables. Spearman Correlation Coefficient (SCC) was used to account for the nonlinearities in the variables’ relationships as well as the indicator’s simplicity. Dekker, E. & Rex, D. K.

Multi-objective cooperative control based on evolutionary Multi-objective cooperative control based on evolutionary

When BALLU’s speed drops considerably, it can recover it through a large footstep. As mentioned in Section 3.5, if it can position both feet forward, the further the feet are put, the larger acceleration the body gains when it reaches the apex. During this sequence, BALLU can recover both height and velocity, and move on to the next sequence of motions. 3.5 Footstep Position Selection Since the concept of BALLU was first unveiled by Ghassemi and Hong (2016), there have been further studies of robot platforms adopting helium balloons and leveraging their buoyancy force. One noticeable work is the Giacometti Arm designed by Takeichi et al. (2017), a 20-m helium balloon supported robot arm designed for inspection tasks. This manipulator has 20 joints driven by pneumatic and thin artificial muscles. Among mobile platforms, GerWalk by Yamada and Nakamura (2018) is one that is very resemblant to BALLU. Because its body is a helium balloon, it is able to easily traverse stairs and other obstacles with stability. Nayar et al. (2019) of JPL also proposed a balloon based walking robot for Mars exploration. Polter, D. E. Risk of colon perforation during colonoscopy at baylor university medical center. In Baylor University Medical Center Proceedings, vol. 28, 3–6 (Taylor & Francis, 2015).When the robot is in a single support phase ( Figure 5C), there is only one supporting force upward, and additionally, the force needs to support the weight of the swing leg, resulting in the height decreasing, and the body sinking down.

Comput Netw 138:90–107 In BALLU2, to enhance BALLU’s functionality, several changes have been made to the BALLU1’s design. The new iteration of BALLU can primarily be broken up into four components: the balloons, the pelvis link, the leg, the knee joint, and the foot. 2.1.1 Balloons

Soft Robotics 1, 213–223, https://doi.org/10.1089/soro.2014.0008 (2014). As a result, the state vectors x SS and x DS are x S S ≔ [ t S S − , v c , x , v c , x − , v c , z , p c , z , p F F , x ] T and x D S ≔ [ t D S − , v c , x , v c , z , p c , z , p F F , x ] T, where the ‘-’ superscript stands for the value of the previous phase. Considering the analysis in Section 3.2, the result is an acceptable choice and consistent with the author’s experience. 4.2 Function Approximation Because of the complexity and uncertainty of the system, rather than conducting formal nonlinear system analysis, BALLU’s walking performance is first qualitatively assessed by analyzing the pelvis’ trajectories and phase plot.

Hu FJ, Lin JW, Gu HJ (2019) Dynamic linear predictive optimization of flexible robot profiling MFA model. J Sens 2019:1–9 Considering that the multi-balloon profiling control needs to meet the shortest time and the highest copying accuracy, the balloon multi-objective optimization control model can be transformed into the following model [ 21]: All data for analysis were collected in simulation. Not only was nominal walking data from teleoperation collected, but walking sequences that include intentionally elongated and shortened double and single support phases as well as following recovery from such abnormal timings were also recorded. We trained a planar data-driven walking controller with artificial neural networks using the definition of the state and a set of expert data. It is assumed that there are a total of \( M \) control units, among which there are \( N \) control motors. Each control unit is designed with a control motor control parameter of \( C_{m1} ,C_{m2} , \ldots ,C_{mi} \), each control motor involves a control parameter of \( K_{1} ,K_{2} , \ldots ,K_{n} \), and the control time required for each control parameter is \( T_{1} ,T_{2} , \ldots ,T_{n} \). Each time the multi-balloon profiling control target is \( G_{ijk} \), herein \( i \), \( j \) and \( k \) is the first control unit, the first control motor, and the first control single machine parameter.
