Hello Candidate,
The colleges which offers BTech in mechatronic engineering are mostly private universities.
some of them accept JEE score and also have their own entrance exam. Most of these colleges have 5-10 seats reserved for management quota, so you have chances to get a seat without writing any entrance exam.
Here are some colleges  offering mechatronic engineering:
1.Aarupadai Veedu Institute of Technology, Kanchipuram, Chennai

2. Acharya Institute of Technology, Soladevanahalli, Bangalore

3. Akshaya College of Engineering and Technology. Kinathukadavu, Coimbatore

4. AR College of Engineering and Technology, Ambasamudram, Tirunelveli

5. Archana Institute of Technology, Krishnagiri

Affiliated to: Anna University Coimbatore

6. Asia Pasific Institute of Information Technology, Panipat City, Panipat.
All the best:)

Hey Sehas.

See for taking admission in any of the college u must have to clear any of the entrance exam which that college accepts. For example JEE MAINS is one of the common exam to take admission in most of the colleges.

See the branch u want to take admission is one of the rarest branch in the engineering field as it is mixture of mechanical electrical and electronics. So u must be having that type of college too.

Hope this helped u getting some point. Ask if u are having any query.

Good luck
