Wir sind eine deutsch- und englischsprachige Lemmy Community und entwickelten uns aus feddit.de heraus.

Feddit.org dient als Reddit-Alternative im Fediverse.

Wir sehen uns als einen selbstbestimmten Raum, außerhalb der Kontrolle kommerzieller Tech-Unternehmen.

Netiquette wird vorausgesetzt. Gepflegt wird ein respektvoller Umgang - ohne Hass, Hetze, Diskriminierung.

Matrix Room
Matrix Space

We are a German and English-speaking Lemmy community that evolved from feddit.de.

Feddit.org serves as a Reddit alternative in the Fediverse.

We see ourselves as a self-determined space, outside the control of commercial tech companies.

Netiquette is expected. A respectful interaction is maintained - without hate, harassment, discrimination.

Imitation learning from human demonstrations has shown impressive performance in robotics. However, most results focus on table-top manipulation, lacking the mobility and dexterity necessary for generally useful tasks.

In this work, we develop a system for imitating mobile manipulation tasks that are bimanual and require whole-body control. We first present Mobile ALOHA, a low-cost and whole-body teleoperation system for data collection. It augments the ALOHA system with a mobile base, and a whole-body teleoperation interface.

Using data collected with Mobile ALOHA, we then perform supervised behavior cloning and find that co-training with existing static ALOHA datasets boosts performance on mobile manipulation tasks.

With 50 demonstrations for each task, co-training can increase success rates by up to 90%, allowing Mobile ALOHA to autonomously complete complex mobile manipulation tasks such as sauteing and serving a piece of shrimp, opening a two-door wall cabinet to store heavy cooking pots, calling and entering an elevator, and lightly rinsing a used pan using a kitchen faucet.
