Buying & integration notes
RobStride RS01 combines a motor, 7.75:1 planetary reducer and CAN drive. It operates at 36 V nominal supply with 17 N·m peak torque and 1 magnetic encoder. Compare thermal mounting, firmware and the required configuration before ordering.
Select the actuator configuration
RS01 is the manufacturer’s short name for RobStride 01. Match the product label, mounting drawing and firmware to the configuration being quoted.
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 36 VDC. October series table: 15–48 VDC; manufacturer webpage: 24–48 VDC; model manuals: 24–50 VDC. Specify the delivered revision and supported supply range. 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: 395 ±3 g. Chinese and English manuals and the manufacturer webpage: 380 ±3 g. Specify the delivered revision and installed mass in the quotation. Manufacturer webpage: 78.5 × 78.5 × 40 mm. Use the revision-matched mounting drawing and STEP model to check the output flange, fasteners and installation clearance.
The manufacturer webpage lists IP52 and offers an IP67 customization. Specify the required protection and applicable configuration 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 0.1.3.14. 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 599. 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.
