Renesas 2-Axis Robot Arm Reference Guide

Overview

This reference guide details a 2-axis robot arm kit developed by Renesas Electronics. It utilizes 2-phase stepping motors equipped with resolver sensors for precise positional control. The system is driven by RX72M for numerical control and RX24T microcontrollers for motor control, enabling smooth arm movements up to 250 mm/s within a 150 mm x 153 mm range.

Key Features

• Trajectory Control (CP Control): Enables continuous path movements via linear or circular interpolation.
• High Positional Resolution: Achieves 200,000 pulses per revolution for accurate positioning.
• Gearless Direct Drives: Maximizes motor torque and eliminates step-out issues by directly connecting motors to the arm.
• Integrated Design: Reduces size and wiring complexity through integrated mechanical and electrical structures.
• High-Speed Communications: Supports Modbus communications at 2 Mbps via half-duplex RS485.

Applications

This reference kit is suitable for various applications including service robots, small arm robots, automated guided vehicles, machine tool control, and medical equipment.
