Canonical robot record
Overview
The ultraArm is a line of compact desktop robotic arms from Elephant Robotics, aimed at education, research, and prototyping. The flagship P340 model uses a metal structure and high-performance stepper motors to deliver stable, precise motion in a footprint roughly the size of a sheet of A5 paper, making it suitable for classroom desks and small workbenches.
The arm is designed as a multifunctional platform. Out of the box it supports writing and drawing, and with add-on kits it can perform laser engraving and vision-based pick-and-place tasks. It integrates with accessories such as slide rails, conveyor belts, and the myAGV mobile platform, allowing it to be used in more complex automation and training scenarios.
Elephant Robotics positions the ultraArm as an affordable entry point into collaborative robotics, pairing accessible hardware with practical training projects for both educational and research users.

Record changelog
- Name: Ultraarm changed to ultraArm P340 · Jul 29, 2026
brand-official name stylization (2026-07-28 image/name audit)
- Weight: 12 kg changed to 2.9 kg · Jul 9, 2026
tranche-7 verification (corrected): Maker spec: 2.9 kg, agreeing with the core weight_kg column. 12 kg (~4x) matches no ultraArm product.
- Degrees of Freedom: 6 changed to 4 (3+1 axes) · Jul 9, 2026
tranche-7 verification (corrected): Maker spec table says DOF '3+1'; marketed as a 4-axis palletizing-kinematics stepper arm. 6 DOF is wrong (myCobot-class bleed).
- Payload Capacity: 5 kg changed to 650 g (0.65 kg) · Jul 9, 2026
tranche-7 verification (corrected): Maker spec: payload 650 g. Stored 5 kg is a ~7.7x inflation — classic aggregator/wrong-product figure on a sub-kg desktop arm.
- Reach: 700 mm changed to 340 mm working radius · Jul 9, 2026
tranche-7 verification (corrected): Maker spec: working radius 340 mm (the '340' in P340). Stored 700 mm is roughly double and matches no ultraArm variant.
- Repeatability: ±0.03 mm changed to ±0.1 mm · Jul 9, 2026
tranche-7 verification (corrected): Maker spec and launch coverage both say ±0.1 mm. ±0.03 mm is a higher-end cobot figure (Mercury-class bleed, over-states precision 3x).
- Communication: Ethernet, WiFi changed to USB serial (Type-C) and RS485; no Ethernet or WiFi · Jul 9, 2026
tranche-7 verification (corrected): P340 is an ATMega2560 Arduino-class board controlled from an external host over USB serial; CNX spec list gives 'RS485 and USB serial'. Ethernet/WiFi belong to netw
- Max Speed: 100 mm/s changed to 100 mm/s (0.1 m/s) maximum terminal velocity · Jul 9, 2026
tranche-7 verification (corrected): Value string matches maker ('100mm/s' terminal velocity; joints 100°/s), but numeric_value 100 in the m/s canonical unit is a 1000x unit error — must be 0.1.
