The HDSRL lab has two very advanced 3D quadruped robots, referred to as Vision 60, designed and manufactured by Ghost Robotics. Vision 60 is a mid-sized tele-op and autonomous all-terrain ground drone. It weighs approximately 32 kg. Vision 60 has 18 DOFs, of which 12 leg DOFs are actuated. The robot can transverse a range of unstructured terrains and substrates.
We call these robots Balto (the gray robot) and Togo (the silver robot). Balto and Togo were the hero sled dogs who led their teams on the 1925 serum run to Nome to transport diphtheria antitoxin to save the town and surrounding communities from an epidemic.
The HDSRL lab includes three A1 quadrupedal robots. The A1 robot is made by Unitree for agile locomotion and has a maximum continuous outdoor running speed of 3.3 (m/s). It has foot pressure sensors, intelligent depth cameras, LiDAR, and NVIDIA TX2 for Visual SLAM.
The HDSRL lab also includes Minitaur, designed and manufactured by Ghost Robotics. Minitaur is a 6.5 kg 2-DOF leg 8-motor (2 per hip) quadrupedal robot platform. The high-torque brushless motors, high-resolution encoders, and specialized leg design let Minitaur run and jump over difficult terrain. 2DOF legs are good for more than just running; they can sense and exert precise forces as well as manipulate. The robot is capable of running at 2 m/s and turning at 1 rad/s.
Kinova Arm and Motion Capture
The HDSRL lab includes Kinova robotic arms. The Kinova arm is a 4.8kg and 4-DOF arm mounted with a 3-finger end-effector and a payload capacity of 4.2kg. These features make the Kinova arms suitable for manipulating a variety of objects. In addition, it is capable of running low-level controllers at 500Hz and high-level controllers at 100Hz. The Kinova arm is capable of RS-485 communication protocol, and its SDK is compatible with Ubuntu OS. The HDSRL lab also has an OptiTrack motion capture system consisting of twelve Prime 13 cameras (240 FPS at 1.3 MP resolution).
The HDSRL lab includes Jackal, an unmanned ground vehicle (UGV), made by ClearPath Robotics. The robot includes an onboard computer, GPS, and IMU and the ability to add a variety of custom sensing options. Jackal’s comprehensive ROS API provides end-to-end visibility of its operation.
