The AxiDraw's pen holder normally holds the pen parallel to the front face of the vertical pen slide, either vertically or at 45° from vertical. This heavy-gauge aluminum adapter sits between the front face of the vertical slide and the pen clip, and serves to rotate the pen tip an additional 45°, not from vertical but out from parallel to the front face of the vertical slide. This gives the AxiDraw the ability to hold a pen in a 'right handed' grip, as opposed to the normal 'center-handed' (for lack of a better description) position. The right-handed grip makes it possible to hold the pen at a consistent angle suitable for use with regular pens, but also stub, italic, parallel, and chisel-point pens. Compatibility This adapter is compatible only with AxiDraw V3 family pen plotters that mount the pen on a 2-hole vertical slide. This includes all AxiDraw V3/A3 and AxiDraw V3 XLX units, and all AxiDraw V3 units manufactured after February 2017.

Temporary Delay in the Delivery of Unitree Robots Like many other suppliers, we are currently experiencing delays in the delivery of Unitree robots. A shipment from our supplier is currently held in customs, which has unfortunately led to later-than-planned deliveries for previously placed orders. We are actively working with our supplier to resolve this issue and expect more clarity soon, but at this time, we cannot provide any guarantees. Additionally, a new shipment is already on its way, though it will take some time to arrive. Since other suppliers are facing similar challenges, switching to a different provider is unlikely to result in a faster solution. Our top priority remains fulfilling existing orders. If you have any questions or would like to update your order, please do not hesitate to contact our customer service team. We will keep you informed of any further developments. Unitree Go2 series consists of quadruped robots for the research & development of autonomous systems in the fields of human-robot interaction (HRI), SLAM & transportation. Due to the four legs, as well as the 12DOF, this robot can handle a variety of different terrains. The Go2 comes with a perfected drive & power management system, which enables a speed (depending on the version) of up to 3.7 m/s or 11.88 km/h with an operating time of up to 4 hours.
