Warden: Mobile Robot Platform to Explore Rugged Terrain

ServoCity has created a wheeled platform that can explore rugged terrain. Hobbyists and roboticists can build their own all-terrain robotic project on top of the chassis.

Warden is based on a robust platform designed for rapid prototyping and applications to meet your specific needs. They choose to build a wheeled platform to achieve great speed even when the robot performs tasks in a complex outdoor environment. Thankfully to a modular design, this customizable platform is easy to build and generally easier to control.

Behind the Design

Here are some insights about the components and development of the platform.

The body
The body of the robot is built from ABS material and provides two access panels to a storage area. The storage area is large enough to accommodate batteries and electronics.About the dimensions of the platform, the body has 21.5 cm (8.5-inch) in length, 16.5 cm (6.5-inch) in width, and 6.3 cm (2.5-inch) in height.
The motors
Each wheel of the platform is attached to a DC motor with a gear ratio of 62:1. Each electric motor has a rotational speed of 195 RPM and a rated load of 1.6 kgf-cm (22.2 Oz-in).The operating voltage of the DC motor is between 3 and 12VDC. It has a maximum stall current of 4.9A at 12VDC.
The tires
The magic word is big. The wheeled platform has attached four wheels with a diameter of 10.9 cm (4.3-inch). These tires allow the rover to deal with rugged terrain.
Parts and accessories
Three aluminum channels are mounted on the platform to attach a large variety of parts and accessories. Each aluminum channel comes with a large number of holes to mount sensors, cameras, and accessories.
