Hello everybody,

I'm present to you my last robot, he is still under work, and i'd update this topic when i finish a part of this robot and add some pics of my job.


Actually i have or i've make :

- A part of the frame (1.25mm Steel)


- Engines, drills motors, 15 N.m 12V 2A (6A crete)


- 5mm axis for the motors/tracks (Pic comming soon)

- Supports of engines (Pic comming soon)

- Nuts and steels bolts

- All of mechanical tracked parts (Full steel 16 gears and 4 chains)

 The size of one gear : ~ 8 cm.


 Size of one link from the chain : ~1 cm.















In ordered :


To buy :

- Electronics parts

- Larges steel plates (for cover my frame)

- Little steel plates (to make the tracks)

- Screws and nuts for the tracks



My work :



For reason, when i've decid to place my motor, i've realized that the frame was too small, so, i've decide to cut a part of the frame, and i've added two pieces of steel to renforce this part of the frame.

 Now i've receive my tracks parts, i need to buy a 10mm axe to link the motor to the gear.

So far, it looks great!

Thank's, today, i've finish the welds of this part of frame, and i've ordered the all of tracked part !


The frame looks good!! What welding technique did you use? MIG/MAG, MMA or TIG?



Hi Jr, and thanks a lot!

I use arc welding (i'm not sure if the translation is good) to make my frame ;)

The others techniques cost to much for me, i'm only a student x)

hello , if it can help you , on my 4wd drill powered robot i have used 4 motor drivers that i build thanks to this site


it cost me about 20 euros to get the pieces for 5 and about 1 hours (per controler )to build them from dot prototyping board 

if you make the constant output mod for the drill think about some fuses :p (i have installed them after burned some part of one controler)


Thanks, but i have already make my motor controler, with double relay(s), and i've see what is the components who was used in your link, and they take only 22A and -23A, they are a bit weak. I've in my lab a lot of MOSFET who can take 140A (IRF3808).

So, thank you anyway ;)


I am building a simillar tracked UGV. I will post some pictures soon.
