WidowX vs Franka vs ALOHA

Which robot is best for imitation learning and data collection? A detailed comparison.

Quick Comparison

Platform Cost DOF Best For
WidowX 250s ~$5–8K 6 Budget, BridgeData, single-arm
Franka Panda ~$12–15K 7 Force control, compliance, research
ALOHA (bimanual) ~$20K 2×6 Bimanual, Stanford datasets
Mobile ALOHA ~$32K Mobile + 2×6 Whole-body, kitchen, mobile

WidowX

Pros: Low cost, widely used in BridgeData and Open X-Embodiment. Large community, many pre-trained models. Cons: Single arm, no force sensing. Best for: budget-conscious labs, single-arm manipulation, leveraging existing datasets.

Franka Panda

Pros: 7 DOF, force control, compliance. Common in research labs. Cons: Higher cost, fewer public datasets than WidowX. Best for: contact-rich tasks, compliance, research where force matters.

ALOHA

Pros: Bimanual teleoperation, Stanford datasets, kitchen tasks. Cons: Fixed base, higher cost. Best for: bimanual manipulation, tasks requiring two hands.

Mobile ALOHA

Pros: Whole-body, mobile manipulation, cooking demos. Open source. Cons: Most expensive, complex setup. Best for: mobile manipulation, whole-body tasks.
