Robots that feel the world™

Direct-drive quadruped robot


Ghost Minitaur™ is a medium-sized legged robot platform. Its high-torque brushless outrunner motors and specialized leg design let this machine run and jump over difficult terrain. High-speed and high-resolution encoders let the machine see the ground through the motors and adapt faster than the blink of an eye.


Features

Easy to use: the robot can be driven around by joystick out of the box, using different gaits.

Versatile legged machine: the 2DOF legs are good for more than just running. They can sense and exert precise forces, and do basic manipulation.

Sensor integration: industry-standard Picatinny rails and onboard SPI, I2C and UART ensure that additional sensors can enable autonomy.

Unique: Minitaur is the first direct-drive legged robot using conventional rotary electric motors.

Use cases

Gait Research: the four 2DOF legs can be programmed with a wide variety of gaits (including bounding, pronking, walking, and trotting) to explore the tradeoffs of efficiency and power at various speeds and with different payloads

Sensor Platform: in addition to the internal IMU and excellent proprioception, Minitaur is an great sensor platform capable of moving sensors around in the environment as well as controlling the field of view
