Robotic arm

Abstract

The present invention relates to a robot comprising a robotic arm comprising a plurality of joints including a first joint and a second joint, and a plurality of motor assemblies including a first motor assembly and a second motor assembly, and a plurality of circuitries including a first circuitry for controlling the motors of the first and second motor assemblies. Each of the first and second motor assemblies extends along an axis between an output end and a housing end and is configured to cause movement of a joint with respect to an axis by relative movement between the output end and the housing end. The motor assembly comprises a first motor connected to a first gear. The first circuitry is arranged between the first joint and the second joint within the robotic arm and is connected to the motors of the first and second motor assemblies by wires. The first motor assembly is arranged with the output end towards the first circuitry and comprises a first passage extending from the first housing end to the first output end along the first axis and the first wires are extending through the passage of the first motor assembly.
