(See "Brain Chips Give Paralyzed Patients New Powers"). The monkey could both reach with the arm and control a gripper at the end of it with relatively smooth, fast movements.
In case you need to, you can reach with your arm easily.
Don't reach with your arms.
Do not attempt to reach with your arms.
With visual and perhaps tactile feedback from the robot, the monkey might not bother to reach with its own arm anymore.
They recalibrated the decoder each day, and the subject had to relearn the task — move a cursor, reach with a robot arm — every time.
To generate goal-directed movements, such as reaching with the arm at stationary or moving objects, the brain must integrate external inputs (e.g., visual, auditory) relative to target position with intrinsic signals (proprioceptive, vestibular, motor) related to body, head, and eye positions.
The task will be repeated for three trials in three conditions: reach with the less affected arm (condition 1) and with the more affected arm (condition 2), then reach for a larger object with both arms (condition 3) to evaluate spontaneous and bilateral reach.
Submission included silent bared teeth display (SBT), turn away, turn away with SBT, move out of arms' reach, move out of arms' reach with SBT, run away <3 meters, run away <3 meters with SBT, run away >3 meters, run away >3 meters with SBT, prolonged scream, crouch (animal stops resisting aggression and gives up, i.e. during mobbing events), and crouch with SBT.
I've been within arms' reach with some of the best creatives Toronto has to offer and that's been very inspiring and helpful to my own process.
To climb out of the Pit, Kat and I pulled ourselves up using several cold red rails, reaching with our arms and legs, cinder-blocking our muscles against gravity.
