This package includes 4 - QRB1134 IR sensors(Data Sheet) to detect changes in the included encoder wheels. It also includes a bracket with all the necessary hardware to attach the sensors to the Trekker. Two sensors are used for the encoder wheels, the other 2 can be used to look at the floor and determine if there are holes/edges on the floor or white/black contrasts. You can also use these four sensors for Line Following with a Trekker Line Following Bracket.
The stickers attach to the 3.5" wheels or the 4.5" wheels sold with the Trekker Chassis. When the sensors are mounted about 0.2" away from the encoder wheels it will detect the changes between the black and white lines. The OOPic or other microcontroller can be programmed to respond to the sensor readings to keep the Trekker on track and tell it how far its traveled.
These are two brackets that can mount to the bottom of the Trekker to hold photo reflectors. Black and white contrast disks are included that can be read by sensors to allow the microcontroller calculate how far the robot has traveled.
