    Calculating Stopping Distance for a Small Buggy Using a Linear Actuator?

    We are using Arduinos and Pi's and in the programming we will make sure we have a code to kill power and automatically apply break if RF signal is lost or if there is a fault with one of the other systems. The average radius of the pads is 130mm and the coefficient of friction for the pad/rotor...

    Calculating Stopping Distance for a Small Buggy Using a Linear Actuator?

    The design will be a one off, incorporated will be an emergency shut off meaning the brake will automatically be applied if needed and an engine kill switch will be incorporated. If the buggy passes the design stage it will be run in a cordoned off car park that will have been booked out so as...

    Calculating Stopping Distance for a Small Buggy Using a Linear Actuator?

    I am trying to work out how long it would take a small buggy weighing 300kgs to stop when traveling at 10kph and then at 20kph with the operation of a linear actuator. The no load speed of the actuator is 11mm/s and fully loaded speed at (4000 Newtons) is 8mm/s. For the brake to be fully on...

    Stepper Motor or Linear Actuator

    Thanks for your reply. The brake needs to work proportionally, just as in human operation. Therefore slamming on the brake, although would bring it to a stop, would not be favourable as it would mean the buggy would not be ale to slow down gradually or slow to a small velocity and then release...

    Stepper Motor or Linear Actuator

    Hi,I am trying to design a simple autonomous braking system for a 4 wheel drive ATV. The system needs to be as cheap as possible. I have come up with two possible solutions. The use of a linear Actuator to activate the brake or a stepper motor attached in someway to the master cylinder. It needs...
