It's tempting to think the motors and battery will be the heaviest part of a Mini Sumo and therefore should be as low as possible. When adding weight, it is best to add as much as possible to the bottom of the robot. A Mini Sumo robot's center of mass should be as low as possible and its wheels should not be too large to avoid tipping over. Lead is dense, cheap, and easy to cut but is not recommended due to health and safety concerns.īalance. Tungsten putty can be a great way to add weight in oddly shaped areas. It is best to find a pre-cut piece that is exactly the size you need. Tungsten has very high density (19.2 g/cm3) but is extremely difficult to cut. Steel has slightly lower density (7.8 g/cm3) than copper and is much harder to cut, although it is a bit cheaper. Some ways to get there include:Ĭopper and Brass have good density (8.7-8.9 g/cm3) and is not difficult cut even with simple hand tools if you're patient. Making a 10x10cm robot weigh 499 grams can be surprisingly difficult. The heavier the robot, the more weight it will have pushing the tires down against the ring to develop higher traction. A Mini Sumo robot should be as heavy as possible while staying under the 500gram limit.

Textured tires may initially have slightly lower traction, but do not need to be cleaned after every round and can eventually beat slicks that aren't cleaned regularly. Slick tires can provide the best initial performance but lose traction quickly as they pick up dust from the environment and require frequent cleaning. Natural rubber tires used in slot car racing also work well but require much more maintenance. Silicone rubber and Polyurethane tires with a durometer of Shore A 20-30 range work great. The goal of a Mini Sumo is to push hard, so high traction tires are vital. Continued abuse of our services will cause your IP address to be blocked indefinitely.Tires.
