An Autonomous RoboticFish

For Mobile Sensing

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

Introduction:•This project aims to develop an energy efficient, noiseless, untethered swimming robot for mobile sensing.•The robot is propelled by an ionic polymer metal composite actuator and zigbee wireless communication module, a micro controller and a temperature sensor for autonomous navigation, control, and sensing.

•It would be nice if the robot can be powered wirelessly or through energy savings.• To give power to robot the only viable option was onboard batteries.•The lithium ones had an excellent capacity to size ratio .•The output voltage of 3V could generate enough bending in the IPMC actuator while limiting the power consumed in electrolysis.

BULDING :

*MOSFET’s 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 inner filler to support the skin and a structure to hold the receiver board.•A circuit was placed inside an isolated tube and the open ends were sealed using a silicone adhesive.
