The WHILL is an add on component to a wheelchair designed for users to give their manual wheelchairs power. It is an alternative to an electric wheelchair and it provides temporary electric drive. The two hubs have a lithium-ion battery powered 24-volt motor that brings a range of 30 kilometers and a top speed of 12.5 miles per hour. Each one takes about two hours to charge in order for it to be fully functional. The band that connects the hubs is a steering device that works by having the individual lean into the direction they wish to go, so it’s similar to a Segway. 24 independent rollers allow Model M to move seamlessly in any direction, opposed to unwieldy swiveling casters. The 9.8-inch Diameter Omni-wheels can climb over 3-inch obstacles and power through thick, rough surfaces with ease. Model M’s swing away armrests and 5.9-inch forward electric seat slide allow the user to position self for close transfers. This feature allows the user to pull right up to tables and chairs. The electromagnetic brakes prevent unwanted movement on inclines and give added stability while transferring.
