The wheel-based humanoid robots with waist mechanism have large workspace and high agility. The humanoid robot in this paper has a waist mechanism with two parallel driving motors. The waist mechanism connects the vehicle with the trunk of the humanoid robot. The dynamic characteristic of the waist mechanism is affected by the dynamic characteristic of arms and vehicle and the external forces or torques,...
Some biped or wheeled-base humanoid robots have waist mechanism in their body structures. Humanoid robots with waist mechanism have large workspace and high agility. A novel waist configuration with parallel driving motor was introduced in this paper. This waist mechanism is driven by the differential-gear closed transmission. It can realize its pitch and yaw motion separately and composite motion...
For wheel-based humanoid robot, the dynamic stability is also an important question just like for biped robot. This paper unites the new recursive Newton-Euler method for dynamic modeling and the ZMP concept and then obtains the ZMP model of the robot. The merit of this model is that it is a function of the position, velocity and acceleration of joints in joint space and easier to realize realtime...
Aimed at structure of humanoid robot and requirements for control performance, this paper designs and realizes joint controller based on CAN bus, and structures an effective credible control system by connecting all joint controllers, force sensors, task management computer and upper limbs control computer together; and realizes the transmission of audio and video information by wireless LAN; constitutes...
Aiming at humanoid robot structure and requirement for control performance, this paper designs and realizes joint controller based on CAN, and structures an effective credible control system by connecting controllers, force sensors and harmonious level computer together. This paper includes mainly: overall structure of the system, design and implementation of hardware and software, topology of control...
