In the presented paper an analytically force overshoots-free approach is described for the execution of robotics interaction tasks involving a compliant (of unknown geometrical and mechanical properties) environment. Based on the impedance control, the aim of the work is to perform force-tracking applications avoiding force overshoots that may result in task failures. The developed algorithm shapes the equivalent stiffness and damping of the closed-loop manipulator to regulate the interaction dynamics deforming the impedance control set-point. The force-tracking performance are obtained defining the control gains analytically based on the estimation of the interacting environment stiffness (performed using an Extended Kalman Filter). The method has been validated in a probing task, showing the avoidance of force overshoots and the achieved target dynamic performance.

In the paper control algorithm for skid-steering mobile platform is presented. For mathematical model of such an object, expressed in auxiliary coordinates, control law based on the idea of artificial force is introduced. A skid-steering mobile platform is an underactuated control system with a rectangular input matrix. In the approach explored in the paper it was assumed that there exists an additional control input, giving an additional column in input matrix and causing this matrix invertible. Because such an actuator does not exist in reality, this input was kept equal to zero equivalently. Simulations have proved proper work of this method.

In this paper, we present the design and fabrication of a bio-inspired caudal fin actuator for propulsion and maneuvering purposes in a fish-like robot. Shape memory alloy (SMA) composite actuator is customized to provide the necessary work out for the caudal fin. The pocket holes guide, electrical wiring and attachment pads for SMA actuators are all embedded in a single layer of cellulose acetate film, sandwiched between two layers of silicone rubber. Instead of using joints, four SMAs are fixed along the soft structure of the caudal fin and bend this to a certain mode shape. The caudal fin actuator was inspired by Largemouth Bass, which uses sub-carangiform mode swimming and the caudal fin during steady swimming and maneuvering.

Rough terrain robotics is a new emerging research field that has stimulated a high number of works during recent years with the aim to provide more autonomy for outdoor vehicles. The talk will discuss the critical role of design and control in the development of autonomous off-road mobile robot. We will focus on articulated wheeled structure and particularly hybrid wheeled-legged locomotion, and show how they can be useful for autonomous outdoor applications, because articulated wheeled rovers offers both advantages of wheels and legs i.e. velocity for the first and obstacles crossing for the second. Their legs kinematics and compliance will be optimized for ensuring both reactive obstacle crossing and postural balance. High-level control will be also addressed by presenting recent advances in path planning and motion generation for mobile robots navigating autonomously over rough terrain. The main issue here is how we can obtain efficient prediction of rover stability and mobility for on-line path and motion planning.

Acceleration/deceleration (ACC/DEC) motion planning is used to generate smooth motion command. This study focuses on realizing trapezoidal, S-curve and fourth-order ACC/DEC planning using digital convolution. To test and verify the proposed ACC/DEC method, a motion controller is designed and implemented. The FPGA (Field Programmable Gate Array) is used to implement the measurement unit and pulse generator, while the SOPC (System on a Programmable Chip) is used to realize the trajectory generator and PID controller. The FPGA-SOPC based motion controller can improve the integration level of the motion control system and meet the real-time requests. Simulation and experiment results verify that the digital convolution method is effective and the FPGA-SOPC based motion controller is feasible.

The paper is aimed to control design of uncertain linear multivariable plants in conditions of quantized output and external disturbances. control law synthesis is based on the consecutive compensator method. Obtained algorithm provides tracking error of quantized output for the reference signal with fixed accuracy. Accuracy range depends on the quantization step and disturbances bounds. There are simulation results confirming performance of proposed method in the paper.
