Ryobi 40v Robot Mower With 40v Trimmer Whiskers By Jstarne1/ Starnes

Ok , I am taking a liking to the inline arrangement of the drill lithium ion batteries. , what do you guys think?

Right now the drill mounts are just sitting in the holes in drilled out for them , next I will likely use some instamorph to make them fit tighter and then screw them in.

These are the motors and gearboxes I pulled out of the drills while harvesting them.

Pickup up another extended capacity battery to be the second battery that will be wired in parallel with the first for double run time. 40 volts at 4.2 ah. I do have the option to double this at any time with 40v 5ah extended run time batteries which would give a total 10 ah of runtime. This is believe will be what I move to so that the robot can make it through the entire yard without stopping.

I picked up this battery for free from Home Depot today by taking one of the problematic reconditioned batteries back in.

Great work, can't wait to see this in action!

Just thought I'll mention, in your postings you keep referring to the Batteries as 'Lipo batteries' and I believe there lithium-ion batteries. Lipo ( Lithium-polymer ) are a completely different beast to lithium-ion. Lipo's should never be put in parallel as they need to be balanced.

Clever and good looking. I'm enjoying your work. Don't stop posting.

OK so here is my ServoCIty order, Originally I ordered plastic chain and sprockets but I am concerned I will probably break them with the torque of these drill motors which ryobi claims is around 600 oz in of torque and max 400 rpm on low drive mode. So metal chain is probably the way to go to longevity reasons. Hopefully I will get my order by Tues so I can start installing it since that's my next off day.
