One of the great advantages of a tracked robot is its uncanny ability to be able to traverse rough, outdoor terrain. Working in a very similar way to full-size military vehicles such as tanks, tracked robots make use of caterpillar tracks which distribute the weight of the vehicle more evenly, making it easier to travel over rough ground. Although tracked machines are absolutely ideal for outdoor use, the majority still work impressively indoors too and can move over a variety of surfaces, both smooth and rough.
One of the most popular products is the blue Arduino tracked mobile tank kit which comes complete with a 328 Arduino microcontroller, motors, battery and charger and has plenty of room for additional components and sensors. If you need to carry a heavy load, the heavy duty large tracked tank robot kit 10023 is ideal with a load capacity of 40Kgs.
For travelling across tough outdoor terrain, tracked robots are perhaps the best of their kind.
