Devices and systems are described including a walking aid including a linear rod having a first end and a second end, a hand grip disposed in proximity to the first end of the linear rod, two or more extendable and retractable self-leveling load-bearing feet at the second end of the linear rod, at least one sensor configured to detect a parameter of a walking surface in proximity to the second end of the linear rod, and a controller including a microprocessor and circuitry, the controller operably coupled to the two or more extendable and retractable self-leveling load-bearing feet and the at least one sensor, and including circuitry configured to receive information regarding the detected parameter of the walking surface from the at least one sensor and circuitry configured to actuate at least one of the two or more extendable and retractable self-leveling load-bearing feet in response to the information regarding the detected parameter of the walking surface.
