Exoskeleton startup wants to slap robot arms on schoolkids

For educational purposes, of course


Exoskeleton startup Auxivo is aiming to encourage the next generation of cyborgs with the launch of an educational kit dubbed the EduExo Pro, a complete exoskeleton for one arm.

Founded in 2019 as a spin-out from the Rehabilitation Engineering Lab at ETH Zürich, Auxivo's industrial products – the LiftSuit and CarrySuit, with the more powerful CarrySuit Advanced on the way – are designed to assist workers with lifting and carrying tasks.

Its EduExo range, by contrast, focuses less on functionality in the workplace and more on making the entire concept of exoskeletons mainstream through education. A crowdfunding campaign launched in May 2017 brought the original EduExo to life: a low-cost, 3D-printed partial exoskeleton driven by an Arduino microcontroller.

The EduExo Pro goes a stage further. "While the classic EduExo is only an elbow exoskeleton connected to the upper and lower arm," Auxivo's Volker Bartenbach explained, "the EduExo Pro is a complete arm exoskeleton connected to your torso, upper arm, and lower arm. With its 6Nm motor in the elbow and a metal spring in the shoulder, the EduExo Pro can provide you with more support to make it an exciting learning experience."

Like its predecessor, the EduExo Pro is programmed through an Arduino microcontroller and comes with a 10-chapter educational manual – up from the seven of the original model – which includes new material on using the device's built-in electromyograph (EMG) sensor and interfacing the exoskeleton with the Unity 3D engine.

"The EduExo Pro exoskeleton kit aims to bring this 21st-century technology into STEM classrooms and university classes worldwide," Bartenbach claimed, "and inspire more people to learn about this fascinating combination of robotics and biology."

Pricing, however, could be an issue in getting the EduExo Pro into schools. Unlike the low-cost original EduExo, which was available as a set of 3D-printable files and assembly instructions for those who didn't want to buy a complete kit, the EduExo Pro comes with a hefty price tag of CHF 1,090 (around £855 excluding VAT) – though discounts are available for those early adopters willing to take the risk of crowdfunding the project.

It is also unclear whether the company has sized the device, which includes rigid sections for the upper and lower arms and a "textile interface" for the upper body, to cover its target market of both "high school and college students" - to say nothing of the makers, hobbyists, teachers, and professors to whom the company is also hoping to sell the gadget.

The company is currently raising funds for production via crowdfunding platform Kickstarter and claims that, if funding is successful, it will ship all rewards by the end of the year. ®

  • 381,000-plus Kubernetes API servers 'exposed to internet'
    Firewall isn't a made-up word from the Hackers movie, people

    A large number of servers running the Kubernetes API have been left exposed to the internet, which is not great: they're potentially vulnerable to abuse.

    Nonprofit security organization The Shadowserver Foundation recently scanned 454,729 systems hosting the popular open-source platform for managing and orchestrating containers, finding that more than 381,645 – or about 84 percent – are accessible via the internet to varying degrees thus providing a cracked door into a corporate network.

    "While this does not mean that these instances are fully open or vulnerable to an attack, it is likely that this level of access was not intended and these instances are an unnecessarily exposed attack surface," Shadowserver's team stressed in a write-up. "They also allow for information leakage on version and build."

  • A peek into Gigabyte's GPU Arm for AI, HPC shops
    High-performance platform choices are going beyond the ubiquitous x86 standard

    Arm-based servers continue to gain momentum with Gigabyte Technology introducing a system based on Ampere's Altra processors paired with Nvidia A100 GPUs, aimed at demanding workloads such as AI training and high-performance compute (HPC) applications.

    The G492-PD0 runs either an Ampere Altra or Altra Max processor, the latter delivering 128 64-bit cores that are compatible with the Armv8.2 architecture.

    It supports 16 DDR4 DIMM slots, which would be enough space for up to 4TB of memory if all slots were filled with 256GB memory modules. The chassis also has space for no fewer than eight Nvidia A100 GPUs, which would make for a costly but very powerful system for those workloads that benefit from GPU acceleration.

  • GitLab version 15 goes big on visibility and observability
    GitOps fans can take a spin on the free tier for pull-based deployment

    One-stop DevOps shop GitLab has announced version 15 of its platform, hot on the heels of pull-based GitOps turning up on the platform's free tier.

    Version 15.0 marks the arrival of GitLab's next major iteration and attention this time around has turned to visibility and observability – hardly surprising considering the acquisition of OpsTrace as 2021 drew to a close, as well as workflow automation, security and compliance.

    GitLab puts out monthly releases –  hitting 15.1 on June 22 –  and we spoke to the company's senior director of Product, Kenny Johnston, at the recent Kubecon EU event, about what will be added to version 15 as time goes by. During a chat with the company's senior director of Product, Kenny Johnston, at the recent Kubecon EU event, The Register was told that this was more where dollars were being invested into the product.
