UGV tracked Platform
Hi all,
I came back to the forum with another ambitious project; the creation of an UGV tracked platform.
Is about a medium to large scale robotic platform, with plenty of space to install and test several electronics!!!
Of course cost is bigger than a normal robot but I think that having the right tools and making the right decision about what you must buy you can create a really expensive robot with the minimum cost….
The project is in progress and every time I’ll try to post material of my progress …..
Ok,
Here is my design till now…
I haven’t finished it yet but I have already gathered all the necessary pieces (from commerce, or modified, or 3d printed or made from CNC) to do that…
As you can see the platform is completed 3D designed and the size will be: 65cmX55cmx40cm.

I think you have a small typo there

I'm trying to make something like this:

Without doupt itis an amazing robot, but the cost is very hight (up to 10.000$)
I think that I have approached very close that robot with about 1200 $ cost....
A first general description follows:
1,2) Rubber trucks BD-A (100mmX40mmX36#)
3,4) Left and right motors (24V 300Watt RV30 gearbox)
5, 9) Modified chassis
6) Motor Holder 3D Printed
7,8,10,11,12,13,14,15,,16,17,18,19) Parts of chassis
20) Aluminum motor cover and base for Motor drive, power distribution board and various electronics
21) Aluminum base for Battery and Brain
22,23,24,25,26) Aluminum parts of the cover from the top of the robot
27,28) Motor driver
29) Power distribution board (Splitter board)
30) Emergency stop switch
31,32) Batteries (12V 20AH each)
On the next posts I'll try to focus for every one of these parts, give the costs and the way I made them or the way I modified them ...
I got them from Alibaba (china).I searched :" 24V worm gear motor "and I had a lot of results...and I bought the cheaper ( 120$ each motor )
I could choose the gearbox (for me the best solution was the "RV30 gearbox output speed 50-60 RPM" (I'll explain on next post how we can choose the right gear box )
I also made a pair of aluminum couplers (here in Greece) in order to attach motors on my chassis.
The cost was 60 euro (I can say that was much more expensive than Motors!)
Some photos:
The main board will be something from Parallax....
However in order to test the basic movements (Skid Steering) I used for a while
my radio : AT9 Radiolink and a Pixhawk from a drone.
The robot is to heavy (156 libs),and due to the danger for wrong movements, I put it on a DIY work table in order to achive the right Skid Steering....
As I said on previus post the motors I use need 24V . So unfortunalelly I couldn't use the HB25 motor controller from parallax which can aford 12V, and I bought a SmartDriveDuo30 motor driver. (Unfortunatelly I haven't seen the DHB-10 from Parallax which is much more better...)
Here is a video from my first Skid Steering test

Yes indeed... It is very quiet robot.... You understand it only when pass next to you... See the next video. You can hearing the sound of cicadas even when the robot pass next to the camera ...

1) A UGV with a remote operate robotic arm
2) A UGV platform , base for a tethered drone
3) An outdoor sand writer
4) A UGV with paintball gun
And since it is a GREEK robot, thearm in #1 absolutely need to be able to stack lightweight fluted cylinders to build a Greek temple...
Sand writer is also my favorite project....
I'm in the process of the design a sophisticated sand printing head that will print characters with height 7 dots.....
Sand will be thrown down from 7 holes that will open-close 7 mini servos.....

I found something very similar on ebay for ~$130, so I might get those.
Obtain infinite funding, then build four bare bases. Then make one of each, using open channel radio to simultaneously control all four from the same controller!
Or make the base and add ons modular so a single base module can be fitted with one of many add on functional modules.
That exactly I have done. The UGV chassis skeleton, is strong enough to hold additional weight and I also have specific holes in order to addapl the add-ons .
However for a tethered drone, an hybridic platform such as the discontinued Propeller QuadRover would be the perfect choise because the big need for electric power...
Anyway maybe I'll add small gas-powered generator for that project in the future ....
Using a servo tester, I can check the functionality of each one port.
With the P2....
