Humanoid Robot - Toala

Toala is an ideal robot for developing full-body humanoid robot applications.

Features

Size and strength equivalent to humans

With a height of 1300~1640 mm (variable), a reach of 740 mm, and a cart width of 720 mm, the size of the robot is close to that of humans. The payload of one arm is 6 kg at the worst-case holding posture, which is sufficient to develop many applications.

Sufficient joint configuration for a wide variety of tasks

The joint configuration of 7-axis dual arms, 3-axis waist (yaw, pitch, elevation), 2-axis neck (yaw, pitch), and 4-axis undercarriage (omni-directional mobile base) enables the robot to do tasks with a range of motion similar to human beings in living and working spaces of people.

Torque sensing of arm and waist

By using joint disturbance observers for the arms and waist, external force detection is possible without torque sensors, enabling contact stop and joint flexibility.

ROS support

Because it is ROS-compatible, the robot in Gazebo (a simulator for ROS) and the actual robot can be operated using the same program. This makes it possible to safely verify the robot's behavior. In addition, trajectory planning and self-interference detection using MoveIt! are implemented as standard.

Software

The basic functions required to control a full-body humanoid robot are implemented. Toala can utilize joint impedance control based on torque detection, fall prevention by monitoring ZMP, a state machine for connecting multiple movements, and safety stop based on interference detection. Toala's software is ROS compatible. Therefore, in addition to the easy use of the above functions, state visualization with RViz, trajectory planning using a ROS standard software MoveIt!, and logging and saving of the robot's sensor information (camera images, joint angles, joint torques, etc.) are available.

Force-torque Sensors

This option enables advanced force control at the tip of the arm. A low-profile 6-axis force-torque sensor and an impedance control program are provided.

 

Hands

Three-finger Hand

  • Three finger configuration: thumb + 2 fingers
  • One axis for each finger (3 motors in total)
  • Outputting about 10N force at fingertips
  • Rubber material attached to fingertips and palm

 

Four-finger Hand

  • Four-finger configuration: thumb + 3 fingers
  • Three axes for thumb and 1 axis for each of the others (6 motors in total)
  • Outputting about 10N force at fingertips
  • Rubber material and FSR pressure sensor attached to fingertips and palm

 

Leader-follower Control System

Noitom's motion capture system, Perception Neuron® PRO, is used. This system can be used for motion teaching for machine learning as well as remote control applications. The system provides singularity avoidance, self-interference protection, and a torque-limiting function when the robot is physically constrained (e.g., when pushing a desk from above). It also has functions to enable/disable control of the left and right arms, grippers, neck, waist, and mobile base independently.
