in this project guidance and control of underwater robot, including three engines and propeller attached to it, by fuzzy control has been investigated. fuzzy control is done based on human experience and requiered laws. the robot can also be controlled and guided by the user. this robot may be used in sea or swimming pool environment for finding goal point and locate in desired direction. in ad...

In this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. The robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (SNS) toward the goal. In the case of no obstacle, SNS was a direct path from the robot to goal; however, in the presence of obstacles, SNS was a space around the r...

The Bionic Handling Assistant is one of the largest soft continuum robots and very special in being a pneumatically operated platform that is able to bend, stretch, and grasp in all directions. It nevertheless shares many challenges with smaller continuum and other softs robots such as parallel actuation, complex movement dynamics, slow pneumatic actuation, non-stationary behavior, and a lack o...

This paper addresses the control of a planar, biped robot with one degree of underactuation. Previous work has designed controllers that induce provably, exponentially stable, periodic walking motions at fixed, pre-determined walking rates. These controllers operate in continuous-time during the single support phase of the robot. The present paper shows how to design an event-based PI controlle...

We designed and implemented a wall-following robot that learned appropriate actions from a small set of noisy training examples. We then assessed the effectiveness of this strategy by physically modifying the robot prior to training. Our system used nearest-neighbour classification to make motor command predictions, but we also tested two regression techniques for continuously varying action se...

This paper presents a novel modeling approach for the mechanics of multisegment, roddriven continuum robots. This modeling approach utilizes a high-fidelity lumped parameter model that captures the variation in curvature along the robot while simultaneously defined by a discrete set of variables and utilizes the principle of virtual power to formulate the statics and dynamics of the continuum r...

There is a growing need for robots that can not only function in close proximity to human beings but also physically interact with them safely. This calls for a paradigm shift in the way robots are designed. Towards this end, we propose the use of continuum robots to improve safety in physical human robot interaction (pHRI). Continuum robots have been looked at in the past for applications whic...

Soft robots demonstrate an impressive ability to adapt objects and environments. However, current soft mobile often use a single mode of movement. This gives good locomotion performance in specific environments but poor others. In this paper, we propose leg–wheel mechanism inspired by bacterial flagella it design robot. employs tendon-driven continuum structure replicate the flagellar filaments...
