What is the name of this anime i watched in 2004? I do not know whether is is an anime or cartoon because the channel i watched on only shows dubbed cartoons.
Here are the details


Its a robot-based show
The only robots i could remember are three of them - One was a police themed robot , Another one is an ambulance themed robot and the last one i could remember is a firetruck themed robot.
Each robot is made up of 1 main robot and 4 smaller ones( all of which could turn into vehicles ( police car , ambulance and firetruck respectively)) 
these 5 robots would combine into one awesome , cool-looking robots. The main bot will be the torso and the head while the 4 smaller ones would be the limbs.
All the robots are piloted by kids and together(with the help of the robots) , they became are the firefighters , policeman and the paramedics of the country


These are all the details that lingered in my mind. Sorry for the limited information . Please help me:(

Please note that it is NOT transformers. The robots are controlled by (about) 10 years old paramedics , policeman and firefighters.
Sounds like Brave Police J-Decker. Here's a summary from the wiki:

Brave Police J-Decker was the fifth anime of the Brave Series and aired in Japan during 1994 and 1995.
Brave Police J-Decker returns the series to a subtly lighter tone, focusing more on the concept of &quot;robot as human-built AI construct&quot; emphasized by the previous season's series, Brave Express Might Gaine. Grade schooler Yuuta Tominaga stumbles upon Deckerd, a humanoid robot under construction by the Japanese police, built to fight advanced forms of crime. Yuuta's constant contact with Deckerd gives the robot a &quot;heart&quot;, or personality; when Yuuta is recruited as the &quot;boss&quot; of the &quot;Brave Police&quot; as a result, a true human/robot partnership occurs.

It's got mechas that are Police, Firetruck, and Ambulance themed.

Deckerd: The sentient police robot that transforms into a police cruiser.
Duke: A sentient robot that transforms into an ambulance.
Fire Roader: A massive firetruck that serves as Duke's support vehicle.

They combine in various combinations as well as the &quot;Fire J-Decker Max Cannon Mode&quot;, a combination of all the vehicles.
