A robotic system for autonomously watering, harvesting, weeding, and tending to your garden. Development Channel: #grow-robot
A half inch hex axel is mounted to the larger bevel gear and the gantry frame. The main cartriage is largely floating and only supported by the chain and gear since both motor walls and bevel gears are on bearings and floating freely on the main axel.
Thank you all so much! Please give me feedback on how to improve my devlogs, and consider following if you want to see where this is going!
I finished Cadding the garden bed including screw positions and soil depth.
I am taking a break from the wrist mechanism as I discovered a major flaw with the mechanism that needs some adjustment which I will hopefully complete tomorrow.

I just finished Modeling the differential gearbox in the toolhead, It is powered by 2 stepper motors, and chain.
I am hoping to print out these parts and make a prototype later today

This is the project moving from Crayon Block CAD to Master sketching all of the dimensions and plate layouts in side and top view.
I dimensioned the CORE-XY upper gantry system, and all of the rollers and turret layers on the base.
Also, I have decided to instead of making the bed two rows of garden beds, it will loop around the top to form a U-shaped structure in order to provide increased working area. The total dimensions are 16ft x 10 ft

MS To-do:
I designed the differential gear box mechanism in CAD today, I didn’t have tons of time to work on it, but I got the general dimensions figured out.
It will operate as a differential gearbox for the rotation and the pitch of the main tool-head. I used gearlabs to generate the bevel gears.
I also worked on some designs for the tool head system, and am considering weather or not a tool changer is necessary

This is what I like to call “Crayon CAD” or when the project exists as undetailed blobs.
I have just finished working out some of the basic layout of the gantry structure. It is going to be cantilevered over One side of the rotating base, and the extendable carriage will ride along the 72 inch long 2x2 aluminum tube using bearings and belts.
The main beam is supported by two 2x2 aluminum tubes that form a triangle of support, this design allows for maximum travel length and minimal interaction with plants.
FYI I am currently designing the robot to be compatble with any plant up to 36 inches tall, this includes some smaller types of tomato, pepper, and bean plants.
I also sketched out the roller gantry design before CADing it.

Crayon CAD for the garden bed base is complete! This will be a good frame to start making rough CAD for the gantry system and elevators, along with spacing out the general dimensions before getting into mastersketches.
The current Idea is that the gantry will ride along these 1.5” aluminum tubes, and will be externally belted for linear motion
