About this deal

However, because of the complex interaction between the balloons, which are affected by aerodynamics, and the underactuated rigid body, it is difficult and counter-intuitive to imagine how BALLU should locomote. Trivedi V, Prakash S, Ramteke M (2017) Optimized on-line control of MMA polymerization using fast multi-objective DE.

At its core, BALLU is a bipedal robot attached to a set of helium balloons, which provide sufficient buoyancy force to prevent the robot from falling down. The tether to activate the two balloons and the SPA is composed of 5 silicon tubes with an external diameter of 2. During this sequence, BALLU can recover both height and velocity, and move on to the next sequence of motions.The spring constant is determined so that the legs extend in a double support phase and bend in a single support phase, which assists with controlling BALLU, as will be described in Sections 3. For this reason, colonoscopy for screening and diagnosis of symptomatic diseases may often require sedation and analgesia. These experiments were performed by using an Instron 5564 dual column and blocking SPID from the base to the load cell. For instance, LG Electronics’ CLOi at an airport ( Incheon Airport, 2019) leads passengers to find a route inside the airport and informs them of their flight schedule.

where x f is the next footstep position with respect to the center of mass, T s is the duration of the phase, and x ̇ is the forward speed. V. Multi-objective cooperative control based on evolutionary process optimization of immune algorithm. This study reports a Soft Pneumatic Inchworm Double balloon (SPID) mini-robot for colonoscopy consisting of two balloons connected by a 3 degrees of freedom soft pneumatic actuator.The wing segments close during the following downstroke to create a more powerful downstream force; the smaller the bird robot makes itself, by contracting its wings, the less friction.

Liang ZP, Wang XY, Lin QZ, Chen F, Chen JY (2018) A novel multi-objective co-evolutionary algorithm based on decomposition approach. Aside from the Z height oscillating within an interval, we can also notice that BALLU does indeed stride forward in the X-direction and its velocity trajectory shows a gradual increase from rest.

Though it is not published, LEONARDO from Aerospace Robotics and Control at Caltech (2019) is another bipedal robot with drone-like propellers. An external force that always acts in the opposite direction of gravity is applied to the robot’s pelvis link. By adopting helium balloons and simplifying bipedal locomotion, BALLU is designed to be affordable and lightweight, and these characteristics allow BALLU to be deployed to real-world and service in close proximity to humans. Unlike the majority of robots that can follow the desired trajectory generated by a controller, passive dynamics govern BALLU’s hip joints and the controller has to realize the desired motion considering that the hip joint can only swing freely. PA, USA) and can be activated with a low air pressure ensuring low pressure exerted on the colonic wall.

BALLU2: A Safe and Affordable Buoyancy Assisted Biped

The output force decreases with the extension due to the increase of the resistance of the polymer when it is stretched. In this paper, the next iteration, BALLU2, which is the first implementation that can walk by algorithms, is presented with details on its design and controller. is used for simulation, and a few custom add-ons were developed to better capture BALLU’s unique characteristics. For the design parameters and the knee joint displacement θ within the joint limits, a range of spring constant κ can be obtained from Eq. Lessons learned from the development and deployment of a hotel concierge robot to be operated in a real world environment.Citation: Chae H, Ahn MS, Noh D, Nam H and Hong D (2021) BALLU2: A Safe and Affordable Buoyancy Assisted Biped. The knee joint design is illustrated in Figure 2B: It consists of upper and lower parts, two symmetric torsion springs attached to each side, a metal pin, a tendon wire, and a tendon bolt.
