Fire Bird V ATMEGA2560 Hardware Manual

1. Introduction

Thank for choo ing the Fire Bird V mobile robotic platform. Fire Bird V will help you gain

expo ure to the world of robotic and embedded y tem . With help of it innovative architecture

and adoption of the ‘Open Source Philo ophy’ in it oftware and hardware de ign, you will be

able to create and contribute to complex application that run on thi platform, helping you

acquire experti e a you pend more time with them.

Safety precautions:

•Robot’ electronic i tatic en itive. U e robot in tatic free environment.

•Read the a embling and operating in truction before working with the robot.

•If robot’ battery low buzzer tart beeping, immediately charge the batterie .

•To prevent fire hazard, do not expo e the equipment to rain or moi ture.

•Refrain from di mantling the unit or any of it acce orie once robot i a embled.

•Charge the NiMH battery only with the charger provided on the robot.

•Never allow NiMH battery to deep di charge.

•Mount all the component with correct polarity.

•Keep wheel away from long hair or fur.

•Keep the robot away from the wet area . Contact with water will damage the robot.

•To avoid ri k of fall, keep your robot in a table po ition.

•Do not attach any connector while robot i powered ON.

•Never leave the robot powered ON when it i not in u e.

•Di connect the battery charger after charging the robot.

Inappropriate Operation:

Inappropriate operation can damage your robot. Inappropriate operation include , but i not

limited to:

•Dropping the robot, running it off an edge, or otherwi e operating it in irre pon ible

manner.

•Interfacing new hardware without con idering compatibility.

•Overloading the robot above it payload capacity.

•Expo ing the robot to wet environment .

•Continuing to run the robot after hair, yarn, tring, or any other item i entangled in the

robot’ axle or wheel .

•All other form of inappropriate operation .

•U ing robot in area prone to tatic electricity.

•Read carefully paragraph marked with caution ymbol.

2. Fire Bird V ATMEGA2560

The Fire Bird V robot i the 5th in the Fire Bird erie of robot . Fir t two ver ion of the robot

were de igned for the Embedded Real-Time Sy tem Lab, Department of Computer Science and

Engineering, IIT Bombay. The e platform were made commercially available from the ver ion

3 onward . All the Fire Bird V erie robot hare the ame main board and other acce orie .

Different family of microcontroller can be added by imply changing top microcontroller

adapter board. Fire Bird V upport ATMEGA2560 (AVR), P89V51RD2 (8051) and LPC2148

(ARM7) microcontroller adapter board . Thi modularity in changing the microcontroller

adapter board make Fire Bird V robot very ver atile. You can al o add your own cu tom

de igned microcontroller adapter board.
