Retrotechtacular: The $550K Video Conferencing System Used To Make Bee Movie

The modern office environment has shifted in recent years. Employees are routinely asked to collaborate with co-workers half way around the globe and be camera ready, or whatever passes for webcam ready, in order to telecommute when they are out of office. Every office laptop, tablet, or cell phone these days comes equipped with some sort of camera sensor capable of recording at HD resolution. Twenty years ago, that was not the case. Though tech conglomerates like HP had a different idea of teleconferencing to sell back in 2005 dubbed the Halo Collaboration Studio.

The Halo Studio was a collaboration between HP and Dreamworks that was used during the production of Bee Movie. Studio heads at Dreamworks thought it necessary to install the HP teleconferencing solution inside the New York office of Jerry Seinfeld, the writer of the film, as to allow him to avoid long trips to Dreamworks production offices in Los Angeles. According to the HP Halo Collaboration Studio brochure, “Halo actually pays for itself, not only by reducing travel costs, but also by encouraging higher productivity and stronger employee loyalty.” Certainly Dreamworks believed in that sales pitch for Bee Movie, because the upfront asking price left a bit of a sting.

Less of a singular machine, more of an entire dedicated room, the Halo Studio had a $550,000 asking price. It utilized three 1280×960 resolution plasma screens each fitted with a 720p broadcast camera and even included an “executive” table for six. The room lighting solution was also part of the package as the intent was to have all participants appear true to life size on the monitors. The system ran on a dedicated T3 fiber optic connection rated at 45 Mbps that connected to the proprietary Halo Video Exchange Network that gave customers access to 24×7 tech support for the small sum of $30,000 a month.

Dual-Arm Mobile Bot Built On IKEA Cart Costs Hundreds, Not Thousands

November 3, 2025 by Donald Papp 6 Comments

There are many incredible open-source robotic arm projects out there, but there’s a dearth of affordable, stable, and mobile robotic platforms with arms. That’s where XLeRobot comes in. It builds on the fantastic LeRobot framework to make a unit that can be trained for autonomous tasks via machine learning, as well as operated remotely.

XLeRobot, designed by [Vector Wang], has a pretty clever design that makes optimal use of easy to obtain parts. In addition to the mostly 3D-printed hardware, it uses an IKEA cart with stacked bin-like shelves as its main frame.

The top bin holds dual arms and a central stalk with a “head”. There’s still room left in that top bin, a handy feature that gives the robot a place to stow or carry objects.

The bottom of the cart gets the three-wheeled motion unit. Three omnidirectional wheels provide a stable base while also allowing the robot to propel itself in any direction and turn on a dime. The motion unit bolts to the bottom, but because the IKEA cart’s shelf bottoms are a metal mesh, no drilling is required.

It’s all very tidy, and results in a mobile robotics platform that is cheap enough for most hobbyists to afford, while being big enough to navigate indoor environments and do useful tasks.

DIY Telepresence Robot Built From Off-The-Shelf Parts

November 16, 2018 by Lewin Day 8 Comments

Petite, but it does the job. Note the huge LED headlight in the center.

Telepresence hasn’t taken off in a big way just yet; it may take some time for society to adjust to robotic simulacra standing in for humans in face-to-face communications. Regardless, it’s an area of continuous development, and [MakerMan] has weighed in with a tidy DIY build that does the job.

It’s a build that relies on an assemblage of off-the-shelf parts to quickly put together a telepresence robot. Real-time video and audio communications are easily handled by a Huawei smartphone running Skype, set up to automatically answer video calls at all times. The phone is placed onto the robotic chassis using a car cell phone holder, attached to the body with a suction cup. The drive is a typical two-motor skid steer system with rear caster, controlled by a microcontroller connected to the phone.

Operation is simple. The user runs a custom app on a remote phone, which handles video calling of the robot’s phone, and provides touchscreen controls for movement. While the robot is a swift mover, it’s really only sized for tabletop operation — unless you wish to talk to your contact’s feet. However, we can imagine there has to be some charm in driving a pint-sized ‘bot up and down the conference table when Sales and Marketing need to be whipped back into shape.

It’s a build that shows that not everything has to be a 12-month process of research and development and integration. Sometimes, you can hit all the right notes by cleverly lacing together a few of the right eBay modules. Getting remote video right can be hard, too – as we’ve seen before.
