This faux x-ray was created for a Scuba Diving Magazine story about a sea turtle that had been maimed by a boat’s propeller. BTech Innovations, a Turkish company specializing in custom-designed prostheses and implants, got involved. They performed a series of detailed CT scans to create a 3D model of the turtle’s skull and damaged jaw. They then designed a bespoke prosthesis and 3D printed it with a medical-grade titanium alloy that is lightweight yet durable enough for a lifetime in the ocean.
I had some spot illustrations in the June 2015 issue of Popular Mechanics magazine about different technologies that can help detect and defend against MLRS rockets, like the ones used against Ukraine last year. These technologies include Air-Defense Lasers that are in development to burn up scout drones, Portable Air-Defense Radars to help locate these drones, Integrated Targeting Systems that combine information from satellite and UAV imagery, mobile ground radar and acoustic surveillance, and Medium-Range UAVs equipped with arrays of cameras and communication-interception equipment.
What are Mecanum Wheels and how do they work? Mecanum wheels, also known as omni wheels or ilon wheels, consist of a hub with rollers oriented 45° to the axis of rotation. Perfect for tight spaces, they enable conventional forward & backward movement as well as side to side and even rotation. To accomplish this, each wheel turns independently. To move side to side, pairs of wheels oppose one another, like a worm gear or screw.
