ROBOScythe (lawnmower for meadow)

Details

We need a lawnmower which is can cut the higher weed also.

The conception about a 2+1 wheeled cutter.

- Vertical cutter
- 3D local positioning
- Wifi controll
- automatic recharging

Components

1 × Drive block with MG996R 3D printed geared

1 × Drive controller with Digispark (Attiny85) Digispark a micro sized controller. Used for wheel control (forward, turn, sense)

The ROBOScythe almost ready for use.

The new design based on VSLOT 20x20 extruded aluminium

The drive system based on two MG996 servos and GT2 pulleys. Side effect: I created a GT2 Pulley pack on Thingiverse.

The cutting equipment based on a BLDC motor. ( +ESC )

The blade has three wings with Robotic lawnmower razors (from OBI). You can use damilhead optionally

The ROBOScythe blade has a shield. And this shield built it with two pressure sensors.

The third "gear" is a tail and stabilizes the device.

And that's all together.

I restarted the project and I have a new design.

Are you sure? yes | no

Hi, my main problem - what I recognise in lawnmower concepts - the jam and the bottom mounted rotating blades can't cut the higer grass and weeds.
So, This lawnower will walk slowly and all days, and the hair-clippers format can cut the higher grasses without jam and without human help.
My hair-clippers concept imagined with horizontal vibration (not exactly than the attached image)

Are you sure? yes | no

Do you think it might be safer to get rid of the rotating blades and instead duplicate the same concept used in electric hair clippers? http://businessfromhome.jasongregory.biz/en/video/dJU08S7Nx-E/How-stuff-works-Electric-motors-for-electric-shavers-rules-of-thermodynamics
