How to control the position of a load shared between two (servo)motors?
I want to position-control an axis combining the action of two DC servomotors - one of them alone is not powerful enough; I had those available and preferred not to buy a new one. I have not the ...
How to calculate the dimensions of a McKibben actuator based on the force you want it to apply?
I intend on design and build a McKibben hydraulic muscle that can lift 5 tons by itself, it won't be attached to a human or anything like that. I tried to search for methods to calculate the amount of ...
How to find coefficient of friction that will maximize torque?
When using DC motors with a drive wheel (aka "direct drive") to propel a vehicle (e.g. an RC car), force and torque play a role in how efficiently that motor's power is transferred into ...
Doubt regarding publishing of robot in a journal or to be applicable for a presentation
i was just curious about publishing an abstract or stuff like that about a robot I've made all by myself . Do i really need to make a working model of it or 3d solid works or cad will be enough ? . I ...
What geared mechanisms can convert various weak stepper motors drive inputs into a higher torque output?
I'm interested in making an arduino robotic arm for something that need precision and/or torque (like CNC), but first, I'm exploring/searching what I would need and how much it would cost. What I ...
What are the pros and cons of Zip Chain Actuators in robotics? [closed]
Well, I just found out about these Zipper Chain Linear Actuators, but I couldn't find much information comparing these types to other types of actuators. For example, what is the performance of Zip ...
Alternatives to Mount the Motors on Quadcopter
We are doing a quadcopter project and we are at the stage of building the vehicle. However due to lack of attention, the screw holes of the Brushless Motors (Emax CF2822) we bought do not align with ...
Mechanical or electrical engineering for robotic and automation? [closed]
I have decided to pursue a career in automation and robotic. At the moment, I am being torn between Mechanical and Electrical Engineering. I know that both of them relate to my choices of career, and ...
