Drone can transform into a tiny car to slide under small gaps

New Scientist | May 22, 2019

A shape-shifting drone can transform into a car once it touches down. The drone, called FSTAR, can move through a variety of surfaces and environments, making it a potentially helpful tool in search and rescue missions. FSTAR has a wheel and a propeller on each of its four legs. The prototype is about 35 centimeters long and 25 centimeters wide. During operation, a human pilot uses a controller to drive FSTAR and change its configurations. When FSTAR is flying as a quadcopter, its four legs are in the same plane as its body, parallel to the ground.
When it lands and receives the commend to turn into a car, a motor on FSTAR’s body pulls its legs from horizontal to vertical so that its wheels touch the ground. However, instead of being perpendicular to the ground like those of a regular car, FSTAR’s wheels are slanted, similar to the sprawling legs of a spider. Tilted wheels work better than vertical wheels, says David Zarrouk at Ben-Gurion University of the Negev in Israel, one of the drone’s creators.

Agora Raises $33 Million to Reinvent Commercial Materials Procurement in Construction

Agora | August 12, 2021

Agora, the industry-leading commercial construction procurement platform, today announced its $33 million Series B funding round led by Tiger Global, with additional key investments from 8VC, Tishman Speyer, Jerry Yang, Michael Ovitz, DST, LeFrak, and Kevin Hartz. Commercial trade contractors use Agora to order and track materials, automate manual data entry, and bring all their supply chain stakeholders together onto a single platform for seamless communication. Agora's software solution is a crucial component in reducing the cost of construction, helping deliver critical projects that strengthen local communities faster and more efficiently, and reducing materials waste. To make our cities more affordable, the commercial construction industry must adopt new technology. Construction is a $10 trillion industry that employs more than 200 million people worldwide. Yet, according to McKinsey, labor productivity growth in the industry has been stagnant since 1947. "Our cities are facing an affordability crisis," said Maria Rioumine, CEO and Co-Founder at Agora. "Our mission at Agora is to make the built environment faster and more efficient to build. By modernizing the construction supply chain, we can dramatically reduce building costs and help make our cities more affordable and accessible to all." Commercial trade contractors across the US still rely on manual, pen-and-paper processes too often to manage their supply chains. Office teams are overburdened with manual data entry and have to rely on outdated systems that don't work with each other. Field teams have no easy way to select the exact materials they need and track them to delivery. These inefficient processes slow contractors down and lead to miscommunication, project delays, and a huge amount of waste. Agora brings both field and office teams onto one digital platform that saves office teams 75% of the time they spend processing purchase orders, and field teams 38% of the time their foremen spend on materials management. In total, this amounts to $300,000 of potential annual savings for the average Agora customer. Today, Agora is processing more than $140 million in annualized materials orders for its customers. In the last year, the company has grown revenue 760% and expanded across 30 states, all whilst tripling in team size. This strong growth attracted a number of top investors, who proactively offered term sheets and sought to scale Agora's impact. "Agora is defining the future of procurement in construction," said John Curtius, partner at Tiger Global. "Agora's platform delivers an industry-leading experience for commercial trade contractors and is a game changer in modernizing how construction works. We're excited about Agora's strong traction, incredible market opportunity, and proven track record of customer success." During the COVID-19 pandemic, contractors across the country faced severe supply chain disruptions and material price fluctuations. Many turned to Agora to help them manage quotes across different vendors more easily and lock in prices in advance. Using the Agora platform, customers reduced the back-and-forth ordering process that traditionally took five or more days to 24-48 hours, and saved their teams hours a day by eliminating manual data entry and shortening the time it takes to process each PO. "Agora transformed the way we manage our supply chain," John Mraz, owner of Einheit Electric Construction Co. "With Agora, my foremen and purchasing agents can use a platform with Amazon-like speed and integration to make sure the right materials arrive on-site, on time. The digital experience is a boon for recruiting young workers, making the best use of our existing employees, and positioning the entire company to beat our goals and growth metrics." Agora's latest round will boost its focus on recruiting top talent for its growing engineering, sales, customer success, marketing, product, and design teams. The company is also devoting significant resources to research and development as it expands into other trade verticals. About Agora Agora is a materials procurement platform built for commercial trade contractors to reduce overhead costs and increase labor productivity. The platform brings the field, office, warehouse, accounting teams, and suppliers, onto one collaborative platform, allowing contractors to create requisitions, issue purchase orders, and track invoices and deliveries instantaneously.
