Autonomy

‍

‍

Control your robot's autonomy with these buttons:

• Autonomous: the robot is continuously autonomous
• Step by step: click to watch your robot make one decision, and one decision only! The robot will take just one step each time you press the button.
• Exploration: in reinforcement learning mode, this button lets you force your robot to occasionally attempt a random action (configurable in the AI tab).

Learning

‍

Control your robot's learning curve:

• Learning: if this button is selected, the robot stores the data supplied in its experience memory and changes the connections in its neural network. It's learning!
  In expert display mode, you have more control:
  • acquire data: if this button is activated, the robot memorizes the actions it performs.
  • Train the model: if this button is activated, the learning algorithm evolves the values of the model parameters.
• Manual editing: in "Manual editing" activities, click this button to modify neural network parameters directly from the interface.
• Forget action: if you click on this button, the robot forgets the last piece of data it learned: very useful if you make a mistake during the learning phase!
• Reset AI: Clicking this button resets the training data and the model, so you can start learning the robot all over again!
  In expert display mode, you have more control:
  • Reset data: deletes stored training data
  • Reset model: model parameters are reset.

Graphs

‍

This button opens a pop-up window giving you information about your robot's training, and graphs that present this data visually. 

‍

This graph tracks the robot's progress by displaying its rewards and the error of its predictions over time. If the robot is progressing well, the reward graph should increase and the error graph should decrease.

If there is too much noise in the data, you can smooth the curves, for example over 2 minutes, by clicking on Smoothing - 2 minutes.

Settings (for AlphAI)

Use this button to set your robot's parameters:

• Speed (from 15 to 50): you can set the robot's speed, depending on the activity and the size of the arena used.
  

• Trajectory correction: the robot may have a small trajectory error. Use this tool to correct it (test using the go straight action).
  

• Accelerated simulation: if you have chosen a simulated robot, this button lets you accelerate the robot's decision-making and actions, instead of imitating real speed.
  

Log off

Use this button to disconnect from the robot, to change the batteries or when your session is over!

⚠️ If you disconnect from the robot, you will automatically return to the home screen. However, if you reconnect the robot and restart the activity without quitting the software, neither the configuration nor your training data will be lost.
