6WD all terrain robot

One of the requirements of this project was the ability to control from a long distance (about 1 km). For this purpose, the following configuration of the transmitter and receiver was used:

1. FrSky TARANIS Q X7 2.4GHz 7CH Transmitter

2. FrSky V8FR - II 2.4G 8CH Receiver HV Version

The robot has been designed to be able to carry a load at least a dozen kilos. For this purpose, I used 6 high-power 12 V brushed DC motors (180 RPM, 27 kg-cm) with metal gearbox. These motors are controlled from six VNH2SP30 Single Motor Drivers that operate from 5.5 to 16 V and can deliver a continuous 14 A (and 30 A peak) per motor.

Chassis of the robot is made entirely from aluminum and duralumin. In this project I used 6 Monster Truck wheels with a diameter of 125 mm which makes it easy to overcome small obstacles.
