Ceiling fan turns into a “spaceship” SCARA robotic arm
Arduino Group — March twenty sixth, 2024
Everyone knows how annoying a ceiling fan could be when it isn’t balanced properly and that annoyance completely demonstrates the need of a very good, sturdy bearing. A ceiling fan’s bearing wants to permit for clean rotational movement with as little friction as doable, whereas fully constraining motion in each different axis. These properties make a ceiling base a surprisingly good start line for a SCARA, as demonstrated in tuenhidiy’s current Instructables write-up.
Of their tutorial, tuenhidiy refers to this as a “Spaceship Scara Arm.” It isn’t precisely clear why they selected the “spaceship” terminology, however it’s much like a traditional SCARA (Selective Compliance Meeting Robotic Arm) — only one with solely two levels of freedom (DOF).
Your entire level of a SCARA is that it’s totally constrained, aside from rotation across the Z axis at every joint. After their ceiling fan broke, tuenhidiy observed that the fan’s base with its beefy bearing can be good for this utility. They took that, added a few stepper motors and belts, some aluminum extrusion, and a pair extra bearings to create this easy SCARA.
An Arduino UNO Rev3 board controls these motors by a CNC Protect V3. Grbl firmware makes it simple to manage the positions of the motors utilizing nearly any software program a person might presumably need. Some easy calculations relating to the arm’s geometry and equipment ratios ought to let applicable software program decide precisely the place it’s in house. For an indication, tuenhidiy added a DC solenoid for its magnetic capabilities. However anybody replicating this undertaking can add their very own finish effector to go well with their wants.
