Part List and Notes for old robot
List of parts and notes on old robot:
List of parts used in old robot:
minibreadboard with standard setup of BX with a 7805 5V regulator
Texas instruments 754410 H-bridge. Datasheet is here.http://focus.ti.com/lit/ds/slrs007b/slrs007b.pdf
Two GM8 gear motors with wheels, runs at 5V from solarbotics: http://www.solarbotics.com/products/index.php?scdfa-250100084-viewDetail-productzq349zq4categoryzq37=true
Sharp GP2D12 Infrared detector, analog. Datasheet here: http://rocky.digikey.com/scripts/ProductInfo.dll?Site=US&V=425&M=GP2D12
Ultrasonic Motion Kit: Info here: http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=120743
Notes:
The motors are DC gear motors, not servo, so they operate on on/off control as opposed to PWM. Less control but easier to program.
Originally, two different sensors were put so one could determine forward/back and the other could determine right/left.
they don't communicate, just sense
to sense eachother, as opposed to sensing the wall, they need something else that tells them its another robot (a light, a magnetic pulse, a RF signal, etc.)
to understand commands, they need to be able to detect, decode and drive new commands (that would mean new code and new or retrofitted components that can decode a serial signal - RF, IR or whatever)
