What is Manual Control? (CR101)

Did you know that in the Cyber Robotics 101 course, you can control the robot manually in simulation?

This is useful for getting to know the robot's environment, mapping out the mission before starting to code, and checking sensor values in the HUD, saving you from having to write programs to test them.

  1. To enable manual control, click the Manual Control button  mceclip0.png  in the Simulation toolbar.
  2. Once enabled, you can use the arrow keys on your keyboard to drive the robot, or click on the navigation controls with your mouse

  3. Hold down the Shift key while pressing arrow keys to drive at turbo speed!

Keyboard Shortcuts

While in Manual Control, there are also several keyboard shortcuts for various actions the robots can perform.

Troubleshooting

Here are a few things to check if you encounter issues with the Manual Control:

  • Some keyboards, mostly on laptops, may have the Numlock activated by default. Turn it off.
  • If the Manual Control icon is pressed but the robot still doesn't move, try clicking in the simulation, then use the arrows


Have fun!
