this paper demonstrates the design and fabrication of an autonomous agricultural drone for sowing seeds in the crop fields. In order to reduce the seeds sowing time, a seed sowing device has been specially developed and integrated withthe quad-copter agricultural drone. the drone consists of a global positioning system (GPS) and an auto-pilot device, the flight path of which is controllable from the ground control station. the flying path can be programmed in the Mission-Planner software before the drone flight starts and can be altered if required. In addition, the agricultural drone is manually controllable using a long-range remote controller. It can fly under variable altitude where the maximum altitude is - 500 meter. the drone can fly at a maximum speed of 14.76 km/hour. the maximum seeds sowing rate of 498 m~2/min is achieved for an altitude of 5 meter. At this seeds sowing rate, the mode value of seeds' distance is ~2.5cm. We can controlthe seeds sowing rate by controlling various operational modes of the seeds sowing device. the proposed agricultural drone will reduce the seeds sowing time significantly and contribute towards the automation of the agricultural sector.

A two-link manipulator can act as a simple robot for various purposes. Present work describes a two-link manipulator for generating a straight line. the problem, although quite straight forward, has many practical implementation issues. this paper describes a numerical model and experiment with two servo motors controlled by a Raspberry Pi and a 12-bit counter motor driver (PCA9685). Various parameters were found responsible for the error in trajectory traversed by the end-effector of a two-link manipulator as compared to the numerical model. the errors in various parameters were incorporated in the numerical model to obtain a better prediction of traversed path. Further, a new control method was proposed and implemented experimentally to obtain a good match with numerical results. the advantage of proposed method is to obtain accurate path generation using low bit resolution motor driver and to overcome motor non-linearity.

In this paper robust controller synthesis for a nonminimum phase (NMP) system in presence of actuator saturation is elaborated. the nonlinear model of a system is encapsulated with a nominal model and multiplicative uncertainties. Two robust control approaches namely mixed sensitivity H ∞ and μ-synthesis are compared from the robust stability and robust performance points of views. Finally, through simulation results it is demonstrated that boththe robust controller approaches have superior performance compared to that of a conventional PID controller, while H ∞ controller performs best.

Human intelligence is deeply dependent on its physical body, and its development requires interaction between its own body and surrounding environment including other agents. However, it is still an open problem that how we can integrate the low level motor control and the high level symbol manipulation system. One of our research goals in the area called "symbol emergence in robotics" is to build a computational model of human intelligence from the motor control to the high level symbol manipulation. In this talk, an unsupervised on-line learning algorithm, which uses a hierarchical Bayesian framework for categorizing multimodal sensory signals such as audio, visual, and haptic information by robots, is introduced at first. the robot uses its physical body to grasp and observe an object from various viewpoints as well as listen to the sound during the observation. the basic algorithm for intelligence is to categorize the collected multimodal data so that the robot can infer unobserved information better and we call the generated categorizes as multimodal concepts. the latter half of this talk discusses an integrated computational model of human intelligence from the motor control to the high level cognition. the core idea is to integrate the multimodal concepts and reinforcement learning. Furthermore, this talk attempts to model communication within the same framework since the self-other discrimination process can be seen as the multimodal categorization of sensory-motor signals.
