First look at a walking robot designed using Hoeken's linkage originally seen in the Chebyshev Plantigrade. This linkage approximates a line that moves at a near constant velocity during one half of its rotation. The robot uses four of these to create a smooth and stable walk with eight legs. While originally intended for military operations or an alternative to wheel chairs, this robot is an excellent example of innovation for households in the future as well. Whether inside or out, many possibilities exist that could benefit from this linkage or system. Some ideas include a lawn mower that is kinder to the yard as legs take steps and won't create ruts in a muddy area like a wheel or a vacuum that makes the transition from hardwood to shag rug easily without needing to be the Hulk to drag it over. Or speaking of heavy and thick flooring, what if chairs walked instead of rolled to not get hung up on them? Maybe toys that used crazy links could excite kids about engineering while also making learning fun. This linkage has been tailored towards advancing legged locomotion within robotics, but can adapt to other settings for other reasons. After its invention 200 years ago, few have bothered to use it. Some see problems, I see potential. This linkage can be simply scaled up or down due to the round even ratios the four bar linkage uses, approximates a line so it can be uses it anything that requires linear motion and smooth operation, and is just fun to use and see in action.
