Mobile Manipulator - Tolon

Tolon is an easy-to-use mobile manipulator that supports the development of next-generation robot applications. It is ideal for the development of autonomous robots that automate material handling tasks in logistics, short-distance transport in factories, security, patrolling, etc.


Easy to use in many situations

  • Footprint close to the size of an electric wheelchair and asymmetrical arm configuration allows it to work in narrow spaces
  • Reaching range is from 0.1 m to 2.1 m above the floor
  • 6 kg payload (at the worst posture) that enables many tasks
  • Sensor-less joint impedance control (precise force control is possible if an optional force sensor is used at the tip of the arm)

Sufficient joint configuration for a wide variety of tasks

The joint configuration of 7-axis arm (P, R, P, R, P, R), 2-axis waist (P, Y), 2-axis neck (Y, P), and 4-axis omni-directional mobile base enables the robot to do tasks with a range of motion similar to humans in working spaces of people.

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.

The basic functions required to develop mobile manipulator applications are implemented, such as 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. Tolon'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.
