Here are a couple pics of the robot im working on. I do this just for fun, and for the challenge of getting it all together and working the way i want it too...
the chassis is made from 1/8" polycarbonate and 3 layers of 6oz glass cloth. the wheels are turned from 3/4" aluminum. the battery pack is a 7.4V 730mAh li-poly RCplane battery.
A better pic of the chassis construction. you can also see the hall effect sensor and the magnet in the wheel. i think i will probably add 2-3 more magnets around the wheel for more resolution.
robot with mock-up of PCB. it uses a PIC18F6585 controller, Pololu Micro Dual Serial Motor Controller, Rogue Robotics uMMC Serial Data Storage Module with 1Gig Card, memsic 2 axis accelerometer and a Paralax Ping ultrasonic sensor.
Im still adding 4-8 IR detectors for base station detection, Lynx 433MHz data transmitter, temp and air pressure sensors (just for the fun of it).
so now I need a mission for it and i cant think of anything... the memory card is going to be for mapping data, so it can remember where its been, and easily get back to any of those places. It cant climb stairs and doesnt have enough clearance for outdoor use.
if anyone has any ideas or opinions, i would be glad to hear them...
