Tobas Fail-Safe

Common Specification

Fail-Safe Flow

  • Disarm if a fail-safe is triggered before takeoff.
  • The fail-safe flow is unified and always ends with disarm: RTL -> Land -> Disarm

Conditions That Do Not Trigger Fail-Safe

  1. During manual control
  2. When position and velocity estimation accuracy is low

Behavior

RTL (Return to Launch)

Ascend to the minimum altitude, return to the arming point, land, and disarm.

Land

Land in place and disarm.

Disarm

Stop all motors immediately.

Check Items

Battery Fail-Safe

Trigger Condition

The battery voltage remains below the threshold for a certain period of time.

Behavior

Land

Recovery

None

Radio Fail-Safe

Trigger Condition

S.BUS from the receiver is interrupted for a certain period of time.

Behavior

  • If position can be estimated -> RTL
  • If position cannot be estimated -> Land

Recovery

Resume manual control once S.BUS is detected again.

Rotor Fail-Safe

Trigger Condition

At least one rotor liveliness status becomes false.

Behavior

RTL

Recovery

None

Tobas Fail-Safe

Common Specification

Fail-Safe Flow

  • Disarm if a fail-safe is triggered before takeoff.
  • The fail-safe flow is unified and always ends with disarm: RTL -> Land -> Disarm

Conditions That Do Not Trigger Fail-Safe

  1. During manual control
  2. When position and velocity estimation accuracy is low

Behavior

RTL (Return to Launch)

Ascend to the minimum altitude, return to the arming point, land, and disarm.

Land

Land in place and disarm.

Disarm

Stop all motors immediately.

Check Items

Battery Fail-Safe

Trigger Condition

The battery voltage remains below the threshold for a certain period of time.

Behavior

Land

Recovery

None

Radio Fail-Safe

Trigger Condition

S.BUS from the receiver is interrupted for a certain period of time.

Behavior

  • If position can be estimated -> RTL
  • If position cannot be estimated -> Land

Recovery

Resume manual control once S.BUS is detected again.

Rotor Fail-Safe

Trigger Condition

At least one rotor liveliness status becomes false.

Behavior

RTL

Recovery

None

Tobas Fail-Safe

Common Specification

Fail-Safe Flow

  • Disarm if a fail-safe is triggered before takeoff.
  • The fail-safe flow is unified and always ends with disarm: RTL -> Land -> Disarm

Conditions That Do Not Trigger Fail-Safe

  1. During manual control
  2. When position and velocity estimation accuracy is low

Behavior

RTL (Return to Launch)

Ascend to the minimum altitude, return to the arming point, land, and disarm.

Land

Land in place and disarm.

Disarm

Stop all motors immediately.

Check Items

Battery Fail-Safe

Trigger Condition

The battery voltage remains below the threshold for a certain period of time.

Behavior

Land

Recovery

None

Radio Fail-Safe

Trigger Condition

S.BUS from the receiver is interrupted for a certain period of time.

Behavior

  • If position can be estimated -> RTL
  • If position cannot be estimated -> Land

Recovery

Resume manual control once S.BUS is detected again.

Rotor Fail-Safe

Trigger Condition

At least one rotor liveliness status becomes false.

Behavior

RTL

Recovery

None

Tobas Fail-Safe

Common Specification

Fail-Safe Flow

  • Disarm if a fail-safe is triggered before takeoff.
  • The fail-safe flow is unified and always ends with disarm: RTL -> Land -> Disarm

Conditions That Do Not Trigger Fail-Safe

  1. During manual control
  2. When position and velocity estimation accuracy is low

Behavior

RTL (Return to Launch)

Ascend to the minimum altitude, return to the arming point, land, and disarm.

Land

Land in place and disarm.

Disarm

Stop all motors immediately.

Check Items

Battery Fail-Safe

Trigger Condition

The battery voltage remains below the threshold for a certain period of time.

Behavior

Land

Recovery

None

Radio Fail-Safe

Trigger Condition

S.BUS from the receiver is interrupted for a certain period of time.

Behavior

  • If position can be estimated -> RTL
  • If position cannot be estimated -> Land

Recovery

Resume manual control once S.BUS is detected again.

Rotor Fail-Safe

Trigger Condition

At least one rotor liveliness status becomes false.

Behavior

RTL

Recovery

None

Package Description

Tobas Fail-Safe

Common Specification

Fail-Safe Flow

  • Disarm if a fail-safe is triggered before takeoff.
  • The fail-safe flow is unified and always ends with disarm: RTL -> Land -> Disarm

Conditions That Do Not Trigger Fail-Safe

  1. During manual control
  2. When position and velocity estimation accuracy is low

Behavior

RTL (Return to Launch)

Ascend to the minimum altitude, return to the arming point, land, and disarm.

Land

Land in place and disarm.

Disarm

Stop all motors immediately.

Check Items

Battery Fail-Safe

Trigger Condition

The battery voltage remains below the threshold for a certain period of time.

Behavior

Land

Recovery

None

Radio Fail-Safe

Trigger Condition

S.BUS from the receiver is interrupted for a certain period of time.

Behavior

  • If position can be estimated -> RTL
  • If position cannot be estimated -> Land

Recovery

Resume manual control once S.BUS is detected again.

Rotor Fail-Safe

Trigger Condition

At least one rotor liveliness status becomes false.

Behavior

RTL

Recovery

None
