Mobile, military robot optimized for use in desert environments which can be controlled remotely or autonomously and can collect/ stream video to a VR headset via its front mounted camera. The method of movement is a continuous track, created using steel roller chain connected by fasteners with 3D printed links. These loops sit on a custom designed drive sprocket and idler sprocket with 4 shock absorber loaded roller pins that act as the suspension system.

The drive motors are powered by '18650' batteries, directed by a raspberry pi 4 and connected to a motor controller. For connectivity, a mobile device can connect to the pi's external antenna as it is a WiFi access point. From here, directions can be sent to the robot from the mobile device using the Node Red GUI and additionally, the entirety of the main raspberry pi computer can be accessed for the use of sending custom commands for autonomous movement.
