with the advancement of automobile industry the control for robotics have much attention just because of reliability and time optimization capability with performance. There is a need of an automatic robot which is capable for the cleaning of the room, office, mall etc and this paper is focusing on such prototype. This paper represents the room cleaning robot which has map storage and wall following functionality and all this implemented using Arduino Uno. With the combination of sensor assembly, algorithm and the intelligent dust cleaner shape make him feasible and effective for all type of environments. It has much more benefits over conventional household vacuum cleaners such as there is no need of personal to clean the room, office etc and fulfilling the main purpose for cleaning the room automatically. In the last results show that this robot is saving much money and time for cleaning the rooms, offices, etc

Drag-based swimming is usually accompanied with the shape change of rowing appendages to generate asymmetric force during the power stroke and recovery stroke. To implement this in an aquatic robot, one may actively control the surface area of its legs during the swimming. However, a small sized robot with a limited number of actuators should adjust the surface area of legs in passive manner. For this reason, we proposed a novel articulated leg fringed with micro hair arrays inspired by a water beetle. This leg structures was especially designed to implement an efficient recovery stroke with less resistive force. By interacting with surrounding media (i.e., water), the surface area of the leg structure was adaptively increased and decreased during the power stroke and recovery stroke, respectively. Also, a 5.5 cm long swimming robot with one pair of legs was built to further investigate the performance of the leg structure. It was found from experiments that introducing a relaxation phase between the power stroke and recovery stroke not only could increase the swimming velocity, but it also reduced the number of required swimming strokes to traverse a given distance. Comparing with a non-articulated leg, a robot with articulated legs exhibited negligible backward displacement during recovery stroke.

The development of ammunition production technology directly affects the level of national defense construction, the application of industrial robot improves the automation degree of ammunition production line, but its work path is complex and the craft is numerous, so simulation verification is needed before the actual installation and debugging, domestic simulation research is still in its infancy. This paper uses robotics module of DELMIA software to model its working process, on this basis, the work path setting, robot trajectory optimization and collision and interference detection are carried out, the production process was optimized by PERT diagram and Gantt diagram. The results show that the optimized process improves the production efficiency and saves the working time. This method has reference significance for the application of other robots in specific industries.

A data transmission algorithm applicable to incremental and absolute encoders is presented and implemented on FPGA-based six axis robot experimental platform. When the industrial computer (IPC) requests synchronous position, the absolute position data is transmitted, while the incremental data is transmitted in the other case to reduce the bus load. In addition, the servo control units assign absolute value data and upload tasks to the various control cycles finely, thus avoiding interference with normal servo control beats. Experimental results shown that the servo control units can read the multi-axis absolute encoders data and achieve the precise positioning of the robot system, further improving the performance of the robot system and reducing the cost.

In this paper, a hybrid approach is presented for tracking control of redundant robot manipulators. In this approach, an RBF(Radial Basis Function) neural controller and an adaptive bound is added to the model based controller i.e (CT type controller). The hybrid controller achieves end-effector tracking as well as subtask tracking adequately. The RBF network learns all the existing uncertainties in the system and requires no offline learning. The adaptive bound part approximates unknown bounds on unstructured uncertainties as well as neural network reconstruction error effectively. The Lyapunov approach is utilized to prove the closed loop system to be asymptotic stable. To validate the effectiveness of control scheme numerical simulation study is performed.

The paper provides an efficient and simple method for deterioration & non-deterioration waste separation using pick and place robot. A simplest image processing technique for robotics using Android mobiles is also a part of the work. In India, degradable and non-degradable wastes in streets are separated by humans. Hence human facing lot of communicable diseases. Android mobile with apk file is used to detect the degradable (vegetables) and non-degradable (plastic cover) objects and it will send that information to the microcontroller unit via Bluetooth module. After receiving this information, microcontroller unit will drive the robotic arm for the particular objects. When microcontroller unit receives '1' means from the bluetooth will find the non-degradable object and it will take and put it on to the separate box. Similarly when it receives '0' means robotic arm will find the degradable objects and it will take and put it on to the separate box.

In this paper, an admittance control scheme is proposed for physical human-robot interaction with human subject's intention motion as well as dynamic uncertainties of the robotic exoskeleton. Human subject's intention motion is represented by the reference trajectory. Online estimation of the stiffness is employed to deal with the variable impedance property of the exoskeleton manipulator. An admittance control approach is firstly presented in order to generate a differentiable reference trajectory in interaction tasks. Then a stability criterion can be obtained by the proposed control method. The designed controller includes linearly parameterization and estimation for the unknown items of the dynamics. Bounded and convergent errors are shown in the motion tracking. The experimental results indicate that the proposed control approach enables the human subjects to execute an admittance control task on the exoskeleton robot effectively.

Welding technique is widely used in industrial production, and it also indicates the industrialization of a country. The traditional way of welding consumes much manpower and time and cannot solve the problem of low accuracy. With the development of industrial robot, those problems could be well solved. In this article, we introduce a welding production line based on industrial robot. We take the welding of accessories of auto for instance, researching the key technologies of welding production line based on industrial robot. Such as the identification of welding position based on machine vision, the CAD automatic programming technology aimed at different accessories. At the same time we create the 3-D digital simulation of the production line to test whether it is practicable.
