Zumo - chassis - set of mechanical parts - Pololu 1418

Set of elements for building a chassis for the fightingrobot. It is compatible with the rules of the minisumo competition. The kit includes: tracks, battery container and mounting plate. To build a complete robot there are also required:main board with Arduino controller, apair of motorsmicro series, plow, and fourbatteriesAA.

The Zumo robot has been designed in such a way that the dimensions of the assembled structure cen be placed in a 10 x 10 cmsquare, which is consistent with the international rules of fighting robots.

This product includes only elements for building a chassis with track chassis system. In our offer there is also a kit that contains a plow and hi mail kit Zumo. Below you can find a list of items needed to build a complete robot.

Two Pololu micro motors

Pololu provides a whole series ofmicro-motors with gearboxes. They differ in capacity and volume reflection. The most popular among designers of fightingrobots are versions of the HighPower with gear30:1and50:1.

Table lists the parameters of motor prototypes at a voltage of 6V.

Four AA batteriesTo power the robot, four batteriesAA are required. We recommend you to useNiMH batteries because they have the possibility of multiple charging.

Main board

The controller allows you to build fighting minisumorobot based on the popular ArduinoUnomodule orLeonardo. The board can be mounted on a special chassis, connecting the battery and motorsfrom Pololu micro series.

Arduino moduleThe kit works with both UnoandLeonardo versions. Compatible also with older models with the same distribution of outputs, for example, Arduino Duemilanove.

In addition to the above listed items necessary for the operation, the user can select additional components, such as:

Reflective sensors strip

Allows you to define the white line located on the edge of the ring. Thanks to the dedicated software, the robot can stop itself from falling outside the designated area.

Charger NiMHAllows you to recharge and reuse the NiMH batteries.

Distance sensors

The optical elements to determine where the enemy is. Most often useddigital sensors with a range of 40cm. Their advantages are small size and speed of measurement.
