NXT in-line skater

skater

I found a video that features a skating robot, it moves, but skating? I did a lot of skating myself, so I started to think about a better skating movement.

It occurred to me that while skating around pylons, you don’t need to take your skates of the ground. What you do instead is hard to explain.

I tried to explain my idea to anyone who’d listen in #mindboards, but to no avail. You just have to see it with your own eyes.

It is a really fun thing to build and play around with. I suspect you can find more efficient and inexplicable ways to move and turn.

This is the Mirah code I used in the video:

import lejos.nxt.Motor
import lejos.nxt.Button

def align()
	Motor.A.rotate(360 - (Motor.A.getTachoCount() % 360))
	Motor.C.rotate(360 - (Motor.C.getTachoCount() % 360))
end

speed = 150
Motor.A.setSpeed(speed)
Motor.C.setSpeed(speed)

Motor.A.forward()
Motor.C.forward()

Thread.sleep(20000)

Motor.A.stop()
Motor.C.stop()

align()

Motor.A.backward()
Motor.C.forward()

Thread.sleep(20000)

align()

Motor.A.forward()
Motor.C.forward()

Button.waitForAnyPress()
