​
Overview

Deploying between simulation and a physical robot is extremely simple with GRID due to the parity between simulated and physical robots. The easiest way to do this, is to take a skill that works with a simulated robot and replace the simulated robot with a physical robot. In many cases, this is as simple as changing the object instantiation. Both agents have access to the rest of GRID and the other functionality that we offer.

AirGenCar to JetBot Example

​
Code

Here is an example of a skill that works with AirGenCar, but can be easily modified to work with JetBot. 
from grid.robot.wheeled.airgen_car import AirGenCar
from grid.utils.types import Velocity
agent = AirGenCar()
agent.moveByVelocity(Velocity(0.4, 0, 0), Velocity(0, 0, 0))
This would become: 
from grid.robot.wheeled.jetbot import JetBot
from grid.utils.types import Velocity
agent = JetBot()
agent.moveByVelocity(Velocity(0.4, 0, 0), Velocity(0, 0, 0))

​
Key Differences

The main difference between the two is that AirGenCar has access to the underlying AirGen API, enabling it to control the environment, receive ground truth data, etc. This can be accessed by using the AirGenCar.client field. JetBot does not have this access, but it does have access to the rest of GRID and the other functionality that we offer.

IsaacLocomotion to Go2 Example

​
Code

Here is an example of a skill that works with IsaacLocomotion, but can be easily modified to work with Go2. There is more initial setup required for the IsaacLocomotion as IsaacLab requires ROS. 
from grid.robot.locomotion.isaac_locomotion import IsaacLocomotion
from grid.utils.types import Velocity

agent = IsaacLocomotion()
agent.moveByVelocity(Velocity(0.4, 0, 0), Velocity(0, 0, 0))
This would become: 
from grid.robot.locomotion.go2 import Go2Real
from grid.utils.types import Velocity

agent = Go2Real()
agent.moveByVelocity(Velocity(0.4, 0, 0), Velocity(0, 0, 0))
