The robot uses the tension linear slide to hang from the center lander during autonomous and to lift itself onto the lander during end game.  The tension linear slide is made of REV Robotics materials. It  is raised by a pulley system using surgical tubing instead of string.  The motor is a 60:1 Andy Mark which helps support the robot's weight.  On the top of the tension linear slide is the lift hook to hang from the lander.
