This is a very small light sensor. A photo resistor (also known as a photodector, or photocell) changes resistance depending on the amount of light it is exposed to.
The H8054 PIR motion detection module provides basic motion detection in a small package. Compatible with the Arduino and Raspberry Pi
The HC-SR501 is a passive infro-red (PIR) sensor which is used to detect motion based on the infrared heat in the surrounding area.
This robot uses custom length sides and 13 inch tires with IG52 136 RPM motors. We have included everything to make it ready to run including batteries, chargers, and a controller.
This is a fully assembled LT2-F robot platform. It is our second generation of the LT robot. It is the same chassis and has the same mechanical components as our tactical LT2-F robot. The LT2 is lighter than the HD2 treaded robot.
