URGENT CORRECTION: Emergency stop for hacked hoverboard creations

[@charlesrg]

Have you tested using a battery disconnect as an e-stop ? Heard that it would burn the board. That would be a nice video to show estop options

Is it possible to run slam and GNSS using a Pi and have you tried using any lidars outdoors with success

Hi, Thanks for sharing great knowledge , I want to make 4 wheel drive gocart or mini car .I need differential action by some switch or code so one front wheel stop while turning .Is it possible that if I steer right then only left wheel move and right wheel become freewheel. If I steer left then only right wheel move and left wheel become freewheel.

Hi and thank you. In the second video of this series here : kzbin.info/www/bejne/e2etk3mkh86Ea8k I discuss and link to firmware by Emmanuel Feru and show how to install it. I bet one of the control variants in his firmware work as you describe. My next video will show how to hook up and control with a joystick and differential drive, and you should just need to choose a different variant in the firmware config file I will walk you through. Most of the information is in Feru's firmware page, but I will go into a bit more detail. I have all the footage shot but I also have a little backlog of work and homework, so I can't promise when I'll release the video. Within a couple of weeks, I hope.

@@PracticalRobotics Thank you very much , After my spinal injury I realize that mobility is the biggest problem for disable persons. I want to make an affordable mobility solution so every person with disability can make it. I am web designing and security expert working freelance if you need any help then I will be happy to help you.

A very worthy project. Best wishes on it!

So long as the device has a big red button, is it necessary for the e-stop to be remotely triggered too?

[@PracticalRobotics]

That would depend on the application and operating environment. I would say that if the machine is going to operate remotely (without a human operator literally riding it) then it is very prudent to have a remote E-stop because these can be too far for the operator to get to the button. Even starting at arms reach these can move faster than most people can run to catch up to it and hit the button, so unless the operator is a rider I personally consider a remote E-stop mandatory. For example if it begins toward traffic or a person, can you be sure that you can get to the button? If it's coming toward someone you certainly can't count on them getting to the button before they are run over.
