Abstract
A vehicle for overcoming obstacles includes a wheel having an elastomeric flexible annulus upon which the wheel normally rides. Parallel spaced sprockets receive the annulus and include individual cogs which extend less radially outwardly than the annulus. When an obstacle is encountered, the flexible annulus yields, thereby enabling a protruding cog to engage the obstacle and pivot around it thereby lifting the vehicle over the obstacle.
