how to build a DIY powerful metal rc robot tank #2

Another project of building a robot crawler, but this time I did my homework well. Unlike the previous robot, the whole body is made of aluminum, so this robot weighs about 2 pounds less than the previous robot that weighs over 6 pounds. Another improvement is the ventral spacing, this robot has about 5 cm ventral spacing and the previous robot 2 cm. Another improvement is the diameter of the wheels leading the caterpillar 4 cm to this robot and 1.5 to the previous robot. Equally important is the aesthetics and finish levels that are much better than the previous robot. Tank dimensions: 44X29X9 cm. This robot has a convenient handle for the grip.

The electronics level is much different from the previous robot. It is equipped with a powerful Bershlas engine with 18V working voltage, and also a built-in limb with 1270 revolutions per minute so that the larva can reach 15-20 mph on a level surface.

Each engine is individually connected with a waterproof 120A speed controller. Allowing control of engine speed through the remote. And all this pleasure feeds Samsung's 18-volt lithium battery with a 9-amp capacity and lasts for almost two hours working with the larva.

This robot can travel under challenging terrain conditions such as sea sand, tall vegetation, grass, field, gravel, kurkar, in water up to 4 cm high. The robot is waterproof and can travel on a rainy day too. All electronics in the robot are waterproof and are also enclosed in waterproof units.
