I'm a student at the College of Engineering Trivandrum and this blog is "supposed" to be a record of my journey into the wonderful world of robotics along with my team mates.
SO far, a line follower is in the making.
v1 was made using 2 sensors (IR) and a simple opamp comaparator circuit. It was fast with two 100 rpm motors and 70mm wheels. The base was made of hylum sheet and the third wheel was a small metal castor wheel.
v2 is under construction with 6 sensors, ATMega32 as the controller and with PWM and P ( + I + D ) control.
Currently I'm looking for a way to get diagnostic data from the controller. THere is an LCD but I'm looking for the whole data from the full course run. The default method would be serial comm but my laptop doesn't have a serial port. So, am on the lookout for a simple usb to serial convertor that I could make with a mega8 or mega32 (since I have those on hand).
My other option was bluetooth or XBee. Xbee requires me to get 2 Xbee modules + a XBee USB explorer which costs around 1500 * 2 + 1000 = 4000. Bluetooth would cost me only around 2000. Since it'll take time to buy the bluetooth module and to program it, leaving that option for later when more pressing requirments arise.
