A robotics firm possible most well-known for a demo of its dexterous robotic hand at Amazon re:MARS with Jeff Bezos has now unveiled a brand new sturdy mannequin designed for machine studying analysis, which was developed in collaboration with Google’s DeepMind.
London-based Shadow Robotic has greater than 20 years of robotic design kind behind it, and has had high-profile analysis and business shoppers like NASA, ESA, OpenAI, Google, MIT and a lot of universities on its books through the years.
The place earlier iterations of “the world’s most dexterous humanoid robotic hand” have appeared fairly acquainted from a human perspective, the brand new Shadow Hand – which the corporate says was developed with analysis and insights from the Google DeepMind robotics staff – sports activities three fingers solely, in gripper-like formation.
“A key problem in AI and robotics is to develop {hardware} that’s dexterous sufficient for complicated duties, but in addition sturdy sufficient for robotic studying,” mentioned the corporate in a press assertion. “Robots study by means of trial and error which requires them to soundly take a look at issues in the true world, typically executing motions on the restrict of their skills. This may trigger harm to the {hardware}, and the ensuing repairs will be expensive and decelerate experiments.”
So in addition to being designed with velocity, flexibility and precision in thoughts, the brand new robotic hand can be constructed to endure “a major quantity of misuse, together with aggressive pressure calls for, abrasion and impacts.”

It measures 350 mm in size, and is 165 mm vast and 160 mm excessive (13.78 x 6.5 x 6.3 in). A single finger weighs in at 1.2 kg (2.6 lb), whereas the entire hand suggestions the scales at 4.1 kg (9 lb). And it requires a 48-V/200-W energy provide.
The robotic hand is reported to profit from exact torque management, with every of the fingers capable of muster as much as 10 N of fingertip pinch pressure. The 4 joints of every finger are pushed by motors housed within the base and linked by way of “tendons” and the fingers are able to going from absolutely open to closed in 500 milliseconds.
Every finger is a self-contained unit, and incorporates a lot of 3-DOF tactile sensors on the proximal and center segments, together with a stereo digital camera setup that is pointed on the inside floor of silicone pores and skin masking the fingertip to supply high-resolution, wide-dynamic-range tactile suggestions in actual time – which all mix to assist the robotic become familiar with the world round it “by means of the sense of contact.”

If one of many finger modules suffers deadly harm throughout limit-pushing AI experiments, it may be faraway from the bottom module (which connects to a robotic arm) and changed with a contemporary one for minimal downtime. The tactile sensors can be eliminated/changed if wanted, with the communication community inside the finger capable of register the presence or absence of a sensor and feed related info to a bunch pc routinely.
We do not have pricing for the Shadow Hand, however the firm will display it to the general public for the primary time at ICRA 2024, which is because of open its doorways subsequent week in Yokohama, Japan.
