ROS based firmware for Teensy -- 2

Job ID: 33438908

Budget: $10 – $50 USD

Hi
I need someone who is good with ROS. I need to drive the robot.
I am using Jetson Nano, L298n motor driver, Teensy3.2 and DC motors with Encoders and GY-85.
I need a simple code that can move the rear wheels and steering using ROS. Mostly that subscribe "/cmd_vel" and publish "imu", "vel", or "odom" (reference). I can run the rear wheels using basic arduino script. I just need to use ROS and teleop_twist_keyboard to move the robot. Speed and steering.
I cannot pay more than the budget proposed here. Let's discuss more.
