TECH: 🤖Unitree Unveils AS2-W Hybrid Robot for All Terrain Exploration Unitree has introduced the AS2-W, a hybrid quadruped robot designed to travel across terrain where conventional wheeled vehicles struggle. Its innovative wheeled-leg design allows it to climb rocky slopes, cross shallow streams, and navigate uneven ground while carrying equipment. The compact robot can support a continuous 16-kilogram payload and travel more than 30 kilometers without a load. Rather than following a fixed route, the AS2-W uses pre-trained reinforcement learning to continuously adapt its movements in real time, helping it maintain stability across changing terrain and obstacles. Unitree envisions the robot serving a range of roles beyond industrial inspection, including as a hiking companion, cargo carrier, and exploration platform for environments that are remote, hazardous, or difficult for people to access. The AS2-W reflects a broader shift in robotics, with intelligent machines moving beyond factories and warehouses toward real-world mobility, outdoor exploration, and everyday assistance. 🤖🏔️🌍⚡

A twin delta antenna is a compact full-wave loop antenna designed for the 2-meter amateur radio band. Each triangular loop has sides of approximately 70 cm, 67 cm, and 67 cm, giving a loop circumference of about 204 cm. Since the wavelength at 146 MHz is approximately 205.5 cm, the antenna resonates very close to the center of the 2-meter band. The antenna is fed with 50-ohm coaxial cable at the center feedpoint, providing efficient power transfer for transmitting and receiving VHF signals. A 1:1 current balun (common-mode choke) at the feedpoint may be useful to reduce common-mode currents on the coax and improve radiation symmetry. Fine-tuning the dimensions can help achieve the lowest SWR after construction.
