espect expo 7



On November 6th, 2018, the 12th  annual China International Aviation and Aerospace Exhibition was officially opened in Zhuhai. A large number of new products in the aerospace industry in China were unveiled at the airshow and this year, most civil drone companies were collectively in Hall 10 of the expo as well as the the civil-military Integration Hall and the outdoor exhibition area was also partly on display.


During the afternoon, the industrial-grade drone leader EWATT held a new product launch in the exhibition area and released a multi-load small multi-rotor drone – Espect.

It is understood that the Espect has a weight of only 3.2 kilograms and a running time of up to 30 minutes ( with a load of 400 grams ), which can flexibly replace different loads such as 4K visible light, 10x zoom cameras and infrared thermal imaging cameras. After the release of the new Espect video, Mr. Zhao Guocheng, Chairman of EWATT and Mr. Liao Shikang, Executive Vice President, jointly unveiled the Espect UAV with demonstrations.

It is reported that the Espect adopts the mature eWise multi-rotor flight control system and power platform of EWATT, combined with industrial-grade visible light imaging, a thermal imaging POD system and route planning, among other ground station remote telemetry software’s, widely used in utility inspections, communication base station inspections, police reconnaissance, fire investigations, search and rescue and other fields. Both the arms and the landing gear can be folded and the body of the Espect is small, making installation and preparation work of the UAV easy and simple.


The Espect basic parameter configuration:


Expanded size (without paddle): 540mm*540mm*250mm


Diagonal paddle wheelbase: 665mm


Shell form: fully enclosed waterproof case


Collection form: arm, landing gear folding


Number of rotors: 4


Waterproof rating: ip54


Wind resistance: 8m / s (5)


Working temperature: -40 ° C ~ 65 °

With carrier life: 30min (load 400g)


Payload: 800g



 At the press conference, EWATT also performed the first flight demonstration, using the Espect. Under the control of a certified UAV pilot, the Espect steadily took off and showed the audience a few smart-functions of the aircraft such as take-off and landing, one-button return and automatic piloting.


Speaking about the original intention of developing Espect, Jack, the deputy general manager of EWATT, said in response to a reporter’s question that the original intention of developing a small UAV is to meet the needs of the power-grids and other industries for miniaturization, portability, ease of operation and simple tasks as well as the need for modular equipment. “We have been providing solutions for industrial users with industrial drones, but in recent years industry users represented by the power grid are more inclined to use miniaturized drones as the main models for inspection.”


 However, there are still many points that need to be solved in the mini power inspection drones. For example, when the power inspection is performed, the on-board camera of the same type of minicomputer has insufficient zoom magnifications, pixels are not high enough and most models do not support replacement. Industrial testing equipment such as infrared temperature measurement has many limitations in practical use.


Jack spoke with live media and said that Espect can choose a variety of loads; mounted with a fast interface design, can carry and flexibly replace 4K visible light, 10x zoom cameras and infrared thermal cameras and other different loads. With a modular design, the Espect makes it easier to replace different mounts, which greatly enhances the system’s ease of use, convenience and maintainability, resulting in a significant increase in work efficiency.


“Similar products are prone to fly-aways, link interruptions, etc. in complex environments, and the anti-interference ability is very weak. Espect is designed to take into account the redundancy of the flight control, the electromagnetic compatibility of the circuit, and the anti-interference of the communication link. It’s optimized to work properly in a variety of complex environments, and more in line with the needs of industry users, “said Jack.


“Compared with EWATTs existing star UAV products, Espect realizes the three links of digital transmission, image transmission and remote control. It is understood that the integration of the three major links of civilian drones has been ongoing. With the improvement of the automation of civilian unity “of the three links has become an important trend of development. Jack also stated that with this design, the first can reduce costs. The second can reduce interference. “There may be some interference between the three links in the three frequency bands, which will have some impact. Now the electromagnetic compatibility is much better.


 In addition, the Espect small multi-rotor UAV is equipped with forward and lower-view infrared obstacle avoidance systems to detect obstacles in the 10M range and maintain good maneuverability when the obstacle sensing system is turned on. Espect’s down-view infrared sensor measures distance by measuring changes in reflected light intensity. When flying below 10M, Espect will automatically adjust its height to handle different flight environments and adaptive flight in complex  environments, while using safe and stable completion of the target task. On the basis of strong technology, EWATT has made industrial characteristics of Espect through effective integration, and has the convenience of consumer-grade operation.


It is understood that the Espect ground station software also has a wealth of use functions, such as one-button take-off / landing, one-button return; timing, fixed-point, fixed-range photo; remote control of the gimbal, direct flight, automatic driving and other functions; edit, change, Upload routes (more than 700 editable waypoints); download and analyze flight logs. At the same time, it has a strong human-like computer interaction function and many parameters are designed into the style of instruments, allowing users to intuitively understand the state of the drone during the operation.


 At the press conference, in addition to the new unmanned aerial vehicle Espect and its debut, EWATT also displayed its star products, including EWZ-S8, EWG-E2V, EWG-G3V, EWZ-H6, etc. Industrial drone related airborne equipment, such as the 36X zoom pods, dual-light pods, tilt-camera, delivery module, spotlight module, bullhorn module, etc.
