Choosing this model
Read the product documentationSourcebotics selection notes, based on the published documentation.
Application fit
- CAN joint integration requiring 48 V nominal supply, a 7.75:1 planetary reducer and 2 magnetic encoders.
- Mechanism development with a defined load, speed, duty cycle and thermal mounting arrangement.
Integration planning
- October series table: 7 N·m at 100 rpm with a 150 × 150 mm aluminium plate. Model manuals: 6 N·m at 100 rpm with a 260 × 280 mm plate. Select against the rating and thermal setup specified for the delivered revision.
- October series table: 15–60 VDC. Model manuals and webpage: 24–60 VDC. Select the supply range against the delivered hardware revision.
- Python examples require Python 3.10 or newer, Linux SocketCAN and a compatible CAN adapter. Specify the adapter, CAN bitrate, motor IDs, firmware and selected protocol in the integration brief. Private CAN operation-control frames, CANopen and the separate MIT protocol use different commands.
Selection considerations
- October series table: 418 ±3 g; Chinese manual labelled 261009: 405 ±3 g; English manual labelled 260713: 380 ±3 g; manufacturer webpage: 405 ±5 g. Specify the delivered revision and installed mass in the quotation.
- The base-model webpage lists IP52 and offers IP67 customization. RS02-IP67 is listed separately by the manufacturer; specify the exact variant, connectors and protection requirements in the quotation.
- Include hardware revision, matching firmware, control mode, adapter, cables, mounting drawing and written warranty coverage in the purchase brief.
Buying & integration notes
RobStride RS02 combines a motor, 7.75:1 planetary reducer and CAN drive. It operates at 48 V nominal supply with 17 N·m peak torque and 2 magnetic encoders. Compare thermal mounting, firmware and the required configuration before ordering.
Select the actuator configuration
RS02 is the manufacturer’s short name for RobStride 02. RS02-IP67 is a separate model; specify the base RS02 or the required IP67 variant in the inquiry.
Match torque to the working cycle
October series table: 7 N·m at 100 rpm with a 150 × 150 mm aluminium plate. Model manuals: 6 N·m at 100 rpm with a 260 × 280 mm plate. Select against the rating and thermal setup specified for the delivered revision. Peak torque describes a short-duration load. Define the working speed, hold time, repeated-load cycle and ambient temperature for selection.
Plan power, mounting and clearance
Nominal supply is 48 VDC. October series table: 15–60 VDC. Model manuals and webpage: 24–60 VDC. Select the supply range against the delivered hardware revision. 7 Apk ±10% rated-load phase current; 23 Apk ±10% peak phase current. Size the power supply for the intended duty cycle, bus demands and regenerative-energy arrangement.
October series table: 418 ±3 g; Chinese manual labelled 261009: 405 ±3 g; English manual labelled 260713: 380 ±3 g; manufacturer webpage: 405 ±5 g. Specify the delivered revision and installed mass in the quotation. Manufacturer webpage: 78.5 × 78.5 × 45.5 mm; the series drawing labels a 41.5 mm axial dimension. Check the complete installed envelope against the supplied assembly drawing.
The base-model webpage lists IP52 and offers IP67 customization. RS02-IP67 is listed separately by the manufacturer; specify the exact variant, connectors and protection requirements in the quotation.
Specify control and software access
Python examples require Python 3.10 or newer, Linux SocketCAN and a compatible CAN adapter. Specify the adapter, CAN bitrate, motor IDs, firmware and selected protocol in the integration brief. Private CAN operation-control frames, CANopen and the separate MIT protocol use different commands. The Chinese manual labels additional MIT parameter commands as requiring firmware 0.2.3.32. Match the command set to the supplied firmware.
The Python source uses an MIT licence. For the ROS sample, obtain the applicable licence terms before redistribution and include the required software and adapter documentation in the order.
Prepare a comparable quotation
The October 9, 2026 manufacturer series table lists CNY 699. Use a configuration-specific Sourcebotics quotation for the actuator, adapter, cables, support, delivery terms, freight and taxes. Specify warranty duration, business-use coverage, support arrangements and delivery destination in the written quotation. The English model manual lists commercial use among warranty exclusions; obtain the terms applicable to your business purchase.
