WiBotic, which develops advanced charging and power optimization solutions for aerial, mobile, marine, space and industrial robots, has announced new cutting-edge chargers and transmitters for drones and autonomous mobile robots (AMRs). The new products include efficient charging solutions for robots that operate in several environments, including those in harsh conditions.
The new products include the following:
- OC-262 onboard charger, a passively cooled onboard charger developed as a ruggedized system for the Department of Defense, but now being released for wider use in response to customer demand. WiBotic said passive cooling is beneficial in punishing environments where water, dust, dirt and corrosion are significant concerns. Applications include customers in the oil and gas, mining, construction, marine exploration and agriculture industries. The OC-262 provides up to 300W of power, has no moving parts, supports all common robot battery chemistries, and pairs with a weatherproof receiver. Two models of the OC-262 are available – an ST model with IP20 rating for applications that require passive cooling but can be more open to the environment; and a WP model with IP67 rating for use in outdoor or extreme environments.
- OC-150 onboard charger, designed for UAVs and smaller robots. The OC-150 is a compact and lightweight onboard charger that delivers up to 150W of total power, and up to 10A of current depending on battery voltage. As with other chargers, it supports multiple battery chemistries and has an output voltage range from 9V to 58.5V.
- TR-150 transmitter, a compact transmitter that uses the latest high-efficiency GaN transistors from GaN Systems, a WiBotic partner. This is designed primarily for use with the new OC-150 onboard charger, but also supports all WiBotic chargers when deployed in diverse robot fleets. The transmitter delivers up to 150W of power, and the GaN-driven power amplifier has 95% efficiency – leading to end-to-end wireless power system efficiencies of 85% or more.
- TR-300 transmitter, which offers the same core benefits of the TR-150 but delivers up to 300W of power when paired with the OC-262 or OC-301 onboard chargers.
“These new products are just as exciting for GaN Systems as they are for WiBotic,” said Paul Wiener, vice president of strategic marketing at GaN Systems. “We continue to believe the market for high-power wireless charging systems is going to explode in the coming years, and companies like WiBotic are going to lead the way through the use of GaN technology.”
WiBotic said the company will demonstrate an innovative new use for onboard chargers at the AUVSI Xponential show in Atlanta, which runs through Aug. 19. The company said its onboard chargers can now track and report on individual battery charge cycles, termination voltage, charge rate (amps), and other critical factors through its Commander Fleet Energy Management software.
“When it comes to power delivery for autonomous drones and mobile robots, it’s crucial to innovate with new technologies such as GaN to maximize efficiency,” said Ben Waters, CEO of WiBotic. “These new products not only push that technical envelope, but are also designed to survive in the most extreme operational conditions. When used together with WiBotic software, they now let operators track and optimize the performance of individual batteries within large and diverse collections – whether charging is performed manually or fully autonomously.”
