Hi all! I'm excited to share this project with you, this is the robot RSP, I bought my second ez-b (v3) and having checked with my first robot(MY ROBOT)
, I decided to undertake a larger project, its height will be of 5.4 feet (1.65 m), currently under construction I have the head, and gathered the materials for the traction system, some voltage regulators, 2 rc esc, several batteries, etc..
I enclose a drawing of how it will look when completed and some photos and video. I hope this project will have a mutual sense of teaching and learning for the entire community that will inspire others and that I may be inspired by all your valuable ideas, more information soon.

Ezang's Following, Tracking The Blue Line With ARC
Thanks for teaching us how to track - used ez-builder camera movement tracking, sorry for the squeaking, had the tail...
Ezang's Modified AIML BOT
Modified AIML BOT - I can ask him any question, did not want to make the video too long He is a conversational bot ....
DJ's Adventurebot Chasing Red Ball
Have you ever found something so hipnotic that you can sit and watch it for hours? That's what happened to me after...
-First cut the excess plastic behind the toes and build a palm-size.
-Cut the union also thumb finger and tilt inward to grasp objects with the original design is quite poor, I'm thinking of making a tilt adjustable system that can fix your position with a screw, so I can taste the position more effective.
-Then in hand mount two servos that I have and connect to the fingers (all the fingers except the index finger are connected to a mini 3kg sevo) and separate your index finger of 1.8 kg micro servo. (with this combination of two servos can grab objects, pointing and waving)
- And finally thin cords replace that bring some more elastic fingers, each finger so that its buffer will separate as an individual clutch can adapt to the irregular formai gripping objects (such as a drink)
Do you control your robot and/or hand with the ARC or other software ?
In any case I will use ez-b with ARC software for the entire project.
And incidentally demonstrate the possibilities of ez-b in a big robot.
Ah rgordon; luck with voltage regulators, I got on the circuit board fiberglass with homemade acid formula and black permanent marker for tracks, quite easy and effective.
PC Board Fab in a Box
No etching tank needed
Actually my system is very simple:
1 - components are marked on the plate with a pencil and then with a minibroca taldro with 1 or 1.5 mm.
2 - tracks are drawn with a black permanent marker better.
3-plate is inserted into a tray of homemade acid (hydrochloric acid 2partes to 20% purity, which is in stores cleaning, also known as "heavy water" and one part hydrogen peroxide to clean wounds ) eg 2 glasses of acid, and a glass of hydrogen peroxide)
4 - after a time the acid has been removed from the copper plate (
except the one under permanent marker lines)
Then clean the pen with alcohol (from wounds too) and you are ready.
When you take it out, have no doubt that I will make some nice videos of their hands manipulating objects, but nothing concrete block or gym weights.
The system original coupling between the wheel and the gearbox, had the shape of a star, this is cut and mounted on four large screws last gear.
I also use a hard plastic table (cutting in the kitchen) and manufactured a screw cutro adptacion between the gearbox and the wheel.
This easy axis is removed with a locking nut at each end. Besides the need to mount the L-shaped brackets between the gears and the chassis.
Thin aluminum board, small screws and rope did the rest.
While working slowly and almost time for the robot, watch your projects and breakthroughs ez-b and marvel, and good luck to all the Dj revolution waiting!
Although the servos have strength, fingers are of a plastic-like material rubber and these are twisted slightly, is rather to gesture that manipulation, greetings.
Thanks again!
