On est vendredi, j'ai un mal de tête carabiné mais je me pose quand même devant l'ordi pour vous annoncer une bonne nouvelle ! Firefox 151 sur desktop vient enfin d'implémenter une fonctionnalité que Mozilla refusait catégoriquement de supporter depuis 6 ans : le support de l'API Web Serial.

Alors non, c'est pas un gros mot, hein, ça veut surtout dire qu'un site web ouvert avec Firefox peut maintenant lire et écrire directement sur du matériel que vous branchez en USB, genre un Arduino, un ESP32, une imprimante 3D, une clé crypto ou que sais-je encore, sans que vous ayez à installer le moindre logiciel ou pilote.

Le cas d'usage le plus parlant, c'est le flashage de microcontrôleurs. Avant, pour mettre un firmware sur un ESP32, il fallait installer esptool en Python, ou l'IDE Arduino, galérer avec les drivers série, choisir le bon port à la main. Maintenant des outils comme ESPHome ou Home Assistant font tout ça depuis un onglet, en quelques clics. Vous branchez la carte, le site demande l'autorisation d'accéder au port, et c'est réglé. Adafruit fait pareil pour installer CircuitPython sur ses cartes ESP32-S2.

What is the Gl.iNet Comet Q KVM?

The Gl.iNet Comet Q is a compact KVM-over-IP device built around a different kind of deployment than most existing entries in this category. Instead of focusing on HDMI-connected desktops, servers, or rack hardware, the Comet Q is designed around a direct USB-C connection, allowing it to interface with smartphones, tablets, laptops, and other compatible host devices through a single pre-attached cable. Alongside local access, it also integrates WiFi-based networking, remote internet control, a built-in touchscreen, and USB-C pass-through for power delivery to the connected device. Based on the early demonstration shown during a visit to Gl.iNet in Shenzhen, the Comet Q appears to be aimed at portable remote access, field support, and off-site troubleshooting, while also expanding the wider Comet KVM range into a more mobile and lower-power form factor.

Gl.iNet Comet Q Hardware Specifications

The Gl.iNet Comet Q is built around a notably smaller hardware platform than the rest of the Comet KVM family. According to the specification sheet provided, it uses a dual-core ARM Cortex-A53 processor, paired with 512MB of LPDDR4 memory and 64GB of onboard storage. This places it below the Comet, Comet PoE, Comet Pro, and Comet 5G in raw system resources, but that appears consistent with its intended role as a highly compact USB-C based access device rather than a more traditional full-size KVM endpoint.

In terms of connectivity, the Comet Q differs significantly from the rest of the range. Rather than relying on HDMI input, it uses a USB-C connection with DisplayPort Alt Mode support for video input. This is the key functional distinction in the lineup, as it allows the device to connect directly to supported modern phones, tablets, and laptops without requiring a separate HDMI capture path. The copied specifications also indicate USB 2.0 Type-A and Type-C connectivity, alongside 1 x RJ45 Gigabit Ethernet port.

Wireless support is also listed as part of the Comet Q feature set. The specification sheet references 802.11a/b/g/n/ac/ax support, with 2.4GHz and 5GHz operation included across the lineup. Although the pasted table is clearly the result of OCR and contains some formatting inconsistencies, the Comet Q is positioned as a wireless-enabled KVM device rather than a purely wired one, which aligns with the functionality shown in the demonstration. This is important because the device is intended to support both local network access and wider remote access scenarios.

Power and physical design are clearly central to the Comet Q hardware profile. It is rated for Type-C power input at 5V/2A, with listed power consumption of less than 2.5W, making it the lowest-power device in the copied Comet family specifications. It also includes a 1.8-inch touchscreen, which is smaller than the displays used on some of the larger Comet models, but appropriate for quick status checks, local configuration, and access control on a device intended for portable use.

Environmental and physical figures place the Comet Q firmly in the compact end of the lineup. The operating temperature is listed as 0°C to 40°C, consistent with the rest of the family. The OCR copy of the table does not clearly preserve the final dimensions and weight entry for the Comet Q in the same way as the other models, but the wider specification set still makes clear that this is intended to be a lighter, lower-power, more travel-friendly device than the HDMI-based Comet units already in the range.

What is the Comet Q KVM bringing to the market that is new?

The main distinction of the Gl.iNet Comet Q is its physical design and target use case. Most KVM-over-IP devices are built around HDMI capture and are designed for desktops, servers, mini PCs, or rack-mounted hardware. The Comet Q instead shifts the concept toward a much smaller USB-C based form factor, with a pre-attached cable and integrated display in a body that is intended to be carried and deployed quickly. That makes it structurally different from the more static, cabling-heavy approach seen in much of the current KVM market.

Portability is another clear differentiator. The Comet Q is designed to operate from USB-C power at under 2.5W, which creates a very different deployment model from larger KVM appliances that often assume fixed placement, dedicated power, and a more permanent network setup. In practical terms, this makes the device easier to use in travel scenarios, temporary support jobs, meeting environments, mobile workstations, and short-term remote access situations where carrying a larger HDMI-based KVM would be less practical.

Its support for USB-C connected client devices also broadens the type of hardware that can be managed. The Comet Q is positioned not only for laptops and compact computers, but also for phones and tablets that support the necessary USB-C display and data standards. That gives it a role that is uncommon in the KVM-over-IP space, where Android phones, tablets, and similarly compact devices are not usually the primary focus. In that respect, the Comet Q is not just reducing size, but also changing the class of device a KVM can be attached to.

The single-cable approach is also important. Based on the demonstration and the listed hardware details, the Comet Q is intended to combine connection, control, and power handling through USB-C, while also supporting network access over LAN, WiFi, and remote internet connectivity. That creates a simpler deployment path than a conventional KVM setup that may require separate video, USB, power, and networking connections. The result is a product that appears to reduce setup complexity while extending KVM access to devices and environments that are not well served by existing HDMI-first designs.

How Does the Comet Q Compare with the Rest of the Gl.iNet KVM Lineup?

Within the wider Gl.iNet Comet series, the Comet Q sits as the most specialised and least traditional model in the range. The RM1 Comet, RM1PE Comet PoE, RM10 Comet Pro, and RM10RC Comet 5G are all built around a more conventional KVM design, using HDMI input and, in some cases, HDMI output for passthrough or expanded deployment. The Comet Q moves away from that approach by replacing HDMI capture with USB-C video input via DP Alt Mode, which changes both the kind of device it can connect to and the environments where it is likely to be used.

In hardware terms, the Comet Q is also the most lightweight system in the lineup. Its dual-core ARM Cortex-A53 processor and 512MB of LPDDR4 memory place it below the other Comet devices, which generally use quad-core ARM processors and 1GB of DDR3L memory. Its sub-2.5W power draw is also the lowest figure listed across the range. That lower hardware ceiling makes sense in context, as the Comet Q appears to prioritise mobility, compact deployment, and low power operation over the broader feature scope of the higher-end HDMI-based models.

The other Comet devices are more clearly structured for fixed installations or more complex remote management roles. The Comet PoE adds Power over Ethernet support for simpler networked deployment, the Comet Pro adds both HDMI input and output, and the Comet 5G extends this further with cellular connectivity through 4G LTE and 5G RedCap support. Compared with those, the Comet Q is not trying to be the most feature-rich model. Instead, it fills a separate position by targeting USB-C connected client hardware and a more portable usage model than the rest of the lineup.

This makes the Comet Q less of a direct replacement for the other Comet units and more of a complementary product. The HDMI-based models remain better suited to desktops, servers, fixed workstations, and network infrastructure where traditional video capture and broader connectivity options matter more. The Comet Q, by contrast, is better understood as a compact access tool for modern mobile and USB-C centric devices, where physical size, single-cable deployment, and lower power use are more important than maximum processing resources or infrastructure-oriented connectivity.

Gl.iNet Comet Q KVM Price & Release Date?

At the time of filming, Gl.iNet had not confirmed a final release schedule for the Comet Q, and availability was still being discussed internally. The device shown in Shenzhen appeared to be relatively close to completion from a hardware and interface perspective, but it was still clearly in a pre-release state, with software behaviour, feature scope, and final implementation details still being adjusted. Gl.iNet also indicated that the launch route under consideration could involve Kickstarter, which suggests the company is still assessing demand and market positioning for this particular model.

Pricing was also not final at the time of the demonstration. The only estimate provided was a broad target range of around $100 to $200, with the expectation that the final retail position would likely sit closer to the lower end of that range than the upper end. Until Gl.iNet confirms official launch pricing, regional availability, and a release timetable, the Comet Q remains a revealed but not yet fully commercialised addition to the wider Comet KVM lineup.

"Free the robot" !!!

C'est le slogan de Menlo Research, et pour une fois c'est pas du flan. En effet, leur Asimov v1 est un humanoïde de 1,20 m et 35 kg, entièrement open source ! Tout est fourni gratuitement donc, les plans de la mécanique, les schémas électriques, le modèle de simulation, ainsi que le code embarqué.

Vous avez donc la CAO complète, la nomenclature des pièces, le modèle MuJoCo pour simuler avant même de souder, et le firmware. Ensuite, y'a 2 façons de l'avoir : Soit le kit DIY (499 dollars d'acompte, puis environ 15 000 dollars au final, livré cet été), soit vous sortez la nomenclature complète et le manuel d'assemblage, et vous sourcez chaque pièce à la main. Ça peut faire un beau projet si vous avez un peu de blé mais surtout des compétences en électronique et du temps !

C'est vrai qu'en général, 1 robot "open source" sur 10, c'est un README qui se la raconte avec 3 STL et rien d'autre derrière, mais là je vous promets, c'est du solide. En janvier dernier, Asimov c'était juste une paire de jambes avec 12 degrés de liberté et basta. Et nous voilà quelques mois plus tard avec un humanoïde complet composé de 25 actionneurs (plus deux orteils passifs sur ressort pour le contact au sol), des bras qui lèvent 15 kg chacun, une tête avec caméra et micros, et un haut-parleur dans le torse pour causer.

Asimov v1, le robot humanoïde open source de Menlo Research

Et côté tripes, c'est du sérieux également avec 2 cerveaux à bord, un Raspberry Pi 5 pour le réseau et le média, et un Radxa CM5 pour le contrôle moteur en temps réel. Des bus CAN charrient ensuite les ordres dans tout le squelette. Niveau matériaux, c'est de l'alu 7075 pour les pièces qui encaissent, du nylon PA12 fritté pour le reste. Et la licence matérielle c'est du CERN-OHL-S-2.0 (je ne la connaissais pas celle-là), et de la GPL-2.0 pour le soft. Donc on est sur du vrai open hardware copyleft !

Maintenant, Menlo a baptisé son kit " Here Be Dragons ". Pour ceux qui n'auraient pas la ref, c'est la mention qu'on collait sur les vieilles cartes médiévales pour dire "ici, terrain inconnu, c'est à vos risques et périls".

Et c'est pas un hasard puisque vous devrez compter 50 à 100 heures rien que pour passer du carton de pièces à un robot qui s'allume proprement et sans danger. Attendez, pas pour le faire marcher, hein, juste pour l'allumage. Et utiliser votre imprimante 3D du dimanche pour les pièces porteuses, oubliez. Faudra passer par de l'alu usiné.

En effet, le plastique risque d'avoir du jeu et foutra en l'air les calculs du contrôleur, donc au mieux le robot marchera mal, au pire il viendra vous buter dans votre sommeil. Ensuite, le reste s'imprime, mais en nylon industriel. Et je vous passe la prise de tête avec le câblage des bus CAN et autres petites surprises... Un bidouilleur prévenu en vaut deux !

Du coup, entre lâcher 15 000 balles pour le kit clé en main et tout sourcer soi-même, perso si j'avais la thune (et l'usage d'un robot), j'opterais pour le kit. Mais si vous avez un atelier, une fraiseuse CNC et la patience d'un moine, la version DIY revient sans doute moins cher. Bref, chacun son délire.

Reste la vraie question que vous vous posez surement (ou pas) : Ça vaut quoi face à la concurrence ?

Hé bien un Unitree G1 tourne autour de 16 000 dollars, soit à peu près le même tarif. Sauf que chez Unitree, les plans du bestiau restent propriétaires et je vous parle pas du soft qui balance tout chez nos amis Chinois.

Alors qu'avec Asimov, vous êtes le propriétaire du robot jusqu'à la dernière vis. L'idée de Menlo c'est d'accélérer l'itération en ouvrant complètement leur robot afin que tout ça s'améliore dans un espèce de cercle vertueux. Et surtout les labos et les geeks de tout poil pourront avoir leur robot bien à eux. Sans ça, sur le marché ce sera uniquement Robot Apple, Robot Google, Robot Tesla ou NoName Chinois et voilà... Ce serait dommage quand même, je trouve.

Et si l'idée vous titille, jetez un œil à YOR, un autre robot open source à monter soi-même , ou à ce que coûte vraiment un humanoïde à la maison en 2026 .

Bref, si vous avez 15 000 balles, 100 heures devant vous et l'âme d'un bidouilleur, le bipède vous attend sur GitHub. Et les autres comme moi, regarderont ce dépôt en bavant... ce qui est déjà pas mal ^^.
