This is my attempt to make a ground painter robot in order to scribble on large areas like street, yards or sidewalks.
The project has 3 parts:
Part 1: The main body of the robot (Chassis, electronics, Power etc.)
Part2: The painting mechanism of the robot (I have designed 3 different ways of writing. The problem is still open)
Part3: The programming procedure that makes the several drawings (letters, geometric drawings, images) into command code for the robot
I hope that youll enjoy my journey for this goal and you will find useful information as well as Im waiting for your proposals and your feedback
Part1: The main body of a robot
For this purpose we need a robot with big and strong wheels able to move comfortably.
Arlo and Eddie robots are very suitable for this purpose. Its big and strong wheels are ideal for movements on streets and sidewalks. Both robots have also a lot of space for additional development and mechanisms essentials for the painting
However on my design, I decided to keep only the 2 main wheels (Left and Right) and choose a different chassis design that is close to the Stingray robot
Except of the main wheels, the robot chassis has also 8 aluminum parts, 4 plastic parts from a 3d printer and an aluminum omni wheel .
The owners of a 3d printer know well, that the best way to test a 3d designed accessory is to print it and try its functionality in the real world.
Technical difficulties prevent me to do this so the only I have made till now is to gather the 8 aluminum parts of the chassis and put them together with the Motor Mount and Wheel Kit (#27971) (the wheel kit from Eddie robot).
For those who want to follow this project I strongly recommend the use the Motor Mount & Wheel Kit - Molded Plastic
for many reasons (I ll explain details on my next posts.)
The entire philosophy of the robot follows the logic of the Arlo Robotic Platform System
and will be able to program it using the spin language or the Propeller C
using the SimpleID tool obtaining all the advantages from the ActivityBot programming.
At the moment here are some photos from chassis parts and from a rough assembly
