Maker Chen Liang (陳亮) has launched a information to constructing a Strider’s linkage robotic outfitted with a digicam — offering distant management with a first-person view utilizing a Hardkernel ODROID-GO handheld video games console, constructed within the form of a basic Nintendo Recreation Boy.
“That is the eighth iteration of me constructing the Strider strolling machine,” Liang writes of the mission, which started with an earlier design printed two years in the past. “The supplies required are similar to Strider Digicam Robotic V6, simply [with] a bit larger LiPo [Lithium-Polymer] batteries. This model[‘s] 3D mannequin reserved room for IR [Infrared] sensors, [which] will help to make the robotic extra clever.”
The Strider’s linkage was initially developed as an alternative choice to Theo Jansen’s well-known Strandbeest designs, utilizing ten bars per leg pair to eight for a Strandbeest — boosting effectivity and load-carrying capabilities. The place Liang’s authentic design was huge and flat and carried an Espressif ESP32-CAM module for management and video work, the brand new V8 design is significantly sleeker with a rounded chassis and a brand new microcontroller board at its coronary heart.
The 3D-printed robotic is powered by a LILYGO TTGO T-Journal improvement board, housing an Espressif ESP32 microcontroller, with an Omnivision OV2640 or OV3660 digicam module for the video. The legs are pushed by two 4.3g servos with 360-degree rotation capabilities, and every thing is powered by one or two 702024 LiPo batteries. One of many largest adjustments within the design: a customized stainless-steel crankshaft, bent manually utilizing a 3D-printed mildew to get the advanced form proper.

The robotic is managed from a Nintendo Recreation Boy-style handheld console, exhibiting a dwell video feed on a coloration display above a directional pad for direct management of its actions. The code operating on the gadget is Liang’s personal creation, streaming the video in MJPEG format — although the {hardware} is an off-the-shelf ODROID-GO from Hardkernel.
