These are the same wheels sold with the Trekker Chassis. The wheels are 3.5" in diameter and about 7/8" thick. Two wheels are included and are modified to fit a splined servo shaft such as the Hitec standard servos. It includes 2 long screws for mounting the wheels on the servo shaft.
These wheels are larger drive wheels allowing the trekker to drive faster and add to the Trekker's appearance.
These ball casters make a good third wheel for 3 wheeled robots, or you can use 2 for more balance.
This is a prebuilt custom robot ready to ship. It uses our popular LT2-F chassis with 8ft Zippermast to make surveillance possible from 8 foot high.
The GPS 18x is an OEM, high-sensitivity GPS sensor for use in automotive, fleet vehicle, and electronics applications that require a small, highly accurate GPS receiver.
