Robotics & Industrial Applications

Center for Nondestructive Evaluation

Robotics is an interdisciplinary branch of technology that deals with design, construction, control and operation of a robot. A simple robot is a machine that is embedded with a sensor, a processor and an end effectors whose application may vary depending upon its connected sensors, end effectors and information processing.

Intelligent fire fighting robot:
The robot has a temperature/light sensor as its sensing element for fire and a water sprayer and motors as its end effectors. The robot is capable of detecting the event of fire, trace the exact location of fire and spraying the water to the detected location. The control commands to the end effectors based on the sensory feedbacks are given by the Atmega128 processor.

Wireless surveillance robot:
The surveillance robot can be used for both commercial and defense purposes. The robot consists of an onboard wireless camera that can stream sequence of images through zigbee protocol. The actuators of the robot can be remotely controlled by establishing Bluetooth connection between the processor and the controlling joystick.

Pneumatic powered robotic crane:
The robot is a miniature working model of an industry standard crane whose arm movements are actuated by the pneumatic linear actuators. The robot has one circular degree of freedom provided by the vertically mounted DC motor and three degree of freedom provided by the linear actuators. The robot navigation is achieved through the differential drive of the horizontal DC motors.

Pick and place robot:
The robot has an onboard arm mechanism that act as an mechanical gripper to hold and release the objects. The gripper movement is manually controlled by controlling the actuator and the robot makes a differential motion to move from one point to another.

Miniaturized Mars rover:
The dynamics of the robot is similar to the Mars rover- Curiosity. The robot has an onboard wireless camera mounted on the servo drive which gives a 360 degree field of view of the surroundings. The robot is powered with the 6 differential drive DC motors which is controlled centrally by the Atmega128 processor.

Collision avoidance robot:
The robot is mounted with the array of ultrasonic proximity sensors whose output are monitored by the processor. When a sensor reads a value below its threshold, the corresponding motor is actuated to make the robot turn towards a safer direction
