This paper presents an end-to-end framework for Heatmap-Guided Grasp Detection (6-DoF grip pose detection) that enables low-power and low-latency inference in edge environments to solve the robotic gripping problem of stably grasping and manipulating objects of various shapes, sizes, and orientations, on GAP9 RISC-V SoC. The model is optimized using hardware-aware techniques such as input dimensionality reduction, model partitioning, and quantization, and the feasibility of full on-chip inference is verified through the GraspNet-1Billion benchmark, demonstrating the potential of real-time autonomous manipulation using low-power MCUs.
