The brand new Unitree Go2-W quadruped provides wheels to the toes, providing new sorts of locomotion. | Credit score: Unitree
Unitree Robotics launched its newest quadruped platform, the Go2-W (“W” for wheeled). This can be a variation of its low-cost Go2 quadruped. The brand new Go2-W options wheels as a substitute of “paws,” giving it a novel kinematic design that makes the robotic nimble, environment friendly on onerous surfaces, and able to some new methods.
When working in wheeled mode, the legs of the Go2-W operate like lively shock absorbers, smoothing the journey for the Go2-W physique (and presumable any sensors on board).
The Go2-W shares all the identical fundamental specs because the Go2. This contains Unitree’s proprietary 4D LIDAR L1 with 360°x90° hemispherical ultra-wide recognition. The Go2-W is 70cm x 43cm x 50cm (27.5″ x 16.9″ x 19.7″) and weighs a svelt 18kg (39.7 lbs). The fundamental battery on the Go2-W is similar because the Go2, however the Go2-W features a lengthy endurance model at 15000 mAh.
The video under reveals the Go2-W rolling on 2-4 wheels when wanted. It could additionally stroll like a typical quadruped by locking the wheels and climb over obstacles as much as 70 cm (2.3 ft).
Wheels make lengthy missions extra environment friendly
Unitree isn’t the primary quadruped to connect wheels to a quadruped. Corporations like LimX and ANYbotics have every demonstrated quadrupeds with wheels. The idea of a wheeled quadruped supplies a mixed-modality cell robotic that may use its wheels on onerous, clean surfaces for environment friendly movement. It could then swap to four-legged movement when there are obstacles (like stairs) to maneuver by way of.
Unitree hasn’t shared the value of the Go2-W, however the entry-level Go2 begins at $1600 USD.
The Boston Dynamics Spot and ANYbotics ANYmal are each industrialized quadrupeds, designed to function in excessive situations. The ANYmal is explosion-proof and authorized for operations the place explosive chemical substances or fumes is likely to be current.
Unitree, Boston Dynamics, ANYbotics, and a number of other different cell robotics firms all signed a promise not to sell their solutions for weaponized applications within the navy.
