SPARK IV is a universal robotic research platform based on AVR microcontrollers. SPARK IV is designed by NEX Robotics in collaboration with Embedded Real-Time Systems Lab, Department of Computer Science and Engineering, IIT Bombay.
SPARK IV supports ATMEGA16, ATMEGA32 and ATMEGA 128 microcontroller. It sports a wide range of sensors such as white line sensors, digital and analog proximity sensor, directional light sensor, position encoder etc. It is powered by Litihium ion batteries. It can be controlled remotely with IR remote control. Robot can communicate with other robot or with PC using ZigBee (IEEE 802.15.4) wireless communication module with 80 separate channels.
Current deployment
- Embedded Real-Time Systems Lab, Department of Computer Science and Engineering, IIT Bombay
- Center for Distance Engineering Education Programme (CDEEP) IIT Bombay to teach Embedded Systems course.
