- Librobotcontrol is package of C library which contains examples and testing programs for Robotic control projects used using beaglebone capes like `robotic-cape <https://www.beagleboard.org/boards/beaglebone-robotics-cape>`_ which is sold by beagleboard.org.BeaglBboneBlack(BBB)(am33xx) supports the librobotcontrol package thanks to Deepak khatri, Who Previouly worked upon cape compatibility layer on BBB.BeaglBboneBlack support robotic-cape cape with librobotcontrol package due to device tree overlays which identify the robotics-cape as a specific hardware which can be useful while accesing various pheripherals and devices with roboitic-cape.

- BeagleBone-AI support librobotcontrol package but its been draft and there is not a stable device tree overlays for robotic cape in AI image.
So for using package, have to check the passed results for various drivers and use cape with AI and make changes accordingly.
BeagleBone AI is based on the Texas Instruments AM5729 dual-core Cortex-A15 SoC with flexible BeagleBone Black header and mechanical compatibility.
which supports the AM572x device tree binary files. However, the current implementation has the following problems This proposal will address these issues.

- BeagleBone AI-64 uses TI J721E-family TDA4VM system-on-chip (SoC) which is part of the K3 Multicore SoC architecture.
Each TI evm has an unique device tree binary file required by the kernel. As BeaglBboneBlack need (ti,am33xx) similarly beaglebone-AI64 support (ti,j721e) device tree binary (.dtb).
BeagleBone AI-64 also support librobotcontrol packages but there are less tutorial and not refine code for support librobotcontrol package with new boards. Need to refine the device trees overlays to use this librobotcontrol package with AI-64.
As in librobotcontrol there is no robotic-cape dtb support for beaglebone-AI64 we need to write the device tree overlays.

- BeagleV®-Fire is a revolutionary SBC powered by the Microchip’s PolarFire® MPFS025T RISC-V System on Chip (SoC) with FPGA fabric.
It has the same P8 & P9 cape header pins as BeagleBone Black allowing to stack BeagleBone cape on top to expand it’s capability. Built around the powerful and energy-efficient RISC-V instruction set architecture (ISA) along with its versatile FPGA fabric.
BeagleV-Fire also support the robotic cape with librobotcontrol package and cape gateware for robotic cape is pre-installed in V-fire image `here <https://openbeagle.org/himanshuk/gateware/-/tree/main/sources/FPGA-design/script_support/components/CAPE/ROBOTICS?ref_type=heads>`_ .
but as BBB support the librobotcontrol with more functionality and flexible application, beagleV-fire is not capable for librobotcontrol package due to less number of child node (PWM, GPIO) present in robotic-cape (.dts) file which is pre-installed in V-fire image.
With help of customization for cape gateware in V-fire which Provide more flexibility to board with cape, and librobotcontrol package to support V-fire with robotic cape.

- Main goal of project is to update librobotcontrol package for beaglebone-AI(am5x), beaglebone-AI64(j721e) and beaeglV-fire(polarV-soc) boards.
Primarily librobotcontrol support all the boards but not able to make roboitic-cape as flexible as BBB.
