3D Printed Mower Build Instructions - Parts To Order

The following parts are required to complete the Robot Lawn Mower Project:

Its a good idea to order the parts now, so you can be printing the chassis while waiting for the parts to arrive

 

 

 

Battery

In addition to these parts you will need a 3S 18650 Battery Pack. I used 6x 3S packs in parallel making a 20.4Ah battery. This gave a mow time on a relatively flat garden of 3hrs.  See the instructions here on creating the pack

(To create a 3S pack, 3x 18650 batteries are connected in series). A Li-Ion protector circuit was used to prevent under and over charge of the packs.

I recommend to use the Panasonic 18650B batteries. These are quality reliable  batteries and worth the investment.

 

 

the battery instructions also includes some information on batteries if your unsure how to use them

 

Wheels

Thew rear wheels can be 3D printed using the files on Thingiverse.  1:200 geared motors can be fitted directly to the wheels. An adapter is used to go from the 6mm motor shaft to the 15mm wheel axle.
