Intelligent brains take longer to solve difficult problems

“Brains with reduced synchrony between brain areas literally “jump to conclusions” when making decisions, rather than waiting until upstream brain regions could complete the processing steps needed to solve the problem”

“Synchronization, i.e., the formation of functional networks in the brain, alters the properties of working memory and thus the ability to ‘endure’ prolonged periods without a decision”

Are you able to endure prolonged periods of thinking without jumping to a conclusion?

“Introducing 𝐌𝐨𝐛𝐢𝐥𝐞 𝐀𝐋𝐎𝐇𝐀🏄 A low-cost, open-source, mobile manipulator.”

“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.”

“Goals:

1. Moves fast. Similar to human walking of 1.42m/s.
2. Stable. Manipulate heavy pots, a vacuum, etc.
3. Whole-body. All dofs teleoperated simultaneously.
4. Untethered. Onboard power and compute.”

“To achieve these goals, we mount ALOHA to a mobile base designed for warehouses: Tracer AGV”

“It can carry 100kg, move up to 1.6m/s, while costing only $7k”
