SEMINOR Topic: An Autonomous Robotic Fish For Mobile Sensing DATE: 05-Feb-2010

Introduction:Th is project aims to develop an energy

efficient, noiseless, untet h eredswimming robot for mobile sensing.

Th e robot is propelled by an ionic

polymer metal composite actuator andzigbee wireless communication module,a micro controller and a temperature

sensor for autonomous navigation,control, and sensing.

Evolution of Robotic Fis h :Th e first generation of t h e wireless robotic

fish wad developed by a team of sixstudents, supported by Diversity ProgramsOffice at Mic h igan State University.

Amoung t h em 3 were from ECE Departmentand 2 from Mec h anical Department.

It would be nice if t h e robot can bepowered wirelessly or t h roug h energysavings.

To give power to robot t h e only viableoption was onboard batteries.

Th e lit h ium ones h ad an excellent capacityto size ratio .

Th e output voltage of 3V could generateenoug h bending in t h e IPM C actuator w h ilelimiting t h e power consumed in electrolysis.

Remote control of the robot was the

primary goal for the first generationprototype instead of seeking a generalcommunication solution.Four different commands were send

through remote1. Fast Forward2. Slow Forward3. Left Turn4. Right Turn

BU LDING :*MOSFETs were placed following the micro controller

output to provide sufficient current.Metallic clamps would function as heat sinks once the

circuit is sealed.The radio receiver board were placed back to back for

efficient use of space inside the robotic fish.

Designing :It is desirable for the swimming robot to

have a real fish like appearance.The original design had three components

seeing from out ward, a flexible waterproof

fish shaped outer layer as skin, a light innerfiller to support the skin and a structure tohold the receiver board.A circuit was placed inside an isolated tube

and the open ends were sealed using asilicone adhesive.

* It has beam like tail and it moved upperand lower edges.

Second Generation :* Second generation robotic fish name wasNEMO(Navigating EAP controlledModule with On board resources).* It was used to carry out mobile sensing.

* U ses:It would allow the robot to

set a desired target locationsor come back to the basewithout human interventionto tag interesting events orsensed information liketemperature, chemical,concentration etc.,They also coordinate with

other robots to performunderwater missions.

C onclusion :Hence we shell conclude this by Xbee.Xbee is another module which is widely

in use. It weights 295 grams.Still now also the scientist are inventing

the smallest robotic fish with high speed.
