Actuators for Robotics
Hello! I develop robots to compete and at the moment I am choosing the actuators to the robot arms. Should I buy micro-actuators in order to be precise in the work, or do the standard models have greater life-span? I am not sure what force and speed to use in a certain job, like lifting light loads. Should I apply electric or pneumatic actuators? And does it have any difference in the durability under constant loads in competitions?

I would suggest electric linear actuators, which can be moved with great precision, and can be easily combined with control systems. Micro-actuators are used in light and fine manipulations whereas, standard or mini-actuators are used in heavy elements that require durability. On selection of force, the weight of maximum load and angle of load application should be taken into account and in the selection of speed; the response time of the robot should be considered.
