Have you ever thought of robots that are involved in sports and recreation activities? Robots that could mimic the act of athletes like runners and, gymnasts. Such robots are extremely interesting for robotics enthusiasts, makers, and inventors. One of the sports and recreation activities that attract boys and girls, young and adults are ziplining. Ziplines are designed to transfer cargo or a person from the top to the bottom of the inclined cable. The cargo or the person is propelled by gravity and moves on the cable through a freely rotating pulley. The zipline robot that we are going to make looks like a monkey that moves on a cable by using its two arms. Making such a creature that uses its arms for locomotion on a cable is a challenging task. However, in this tutorial, we are going to make a fun and easy-to-build zipline robot with Lego Technic components, an Arduino board, and some off-the-shelf electromechanical components. The instructions are prepared in a way that you can build them at home.
