Safe motion planning in dynamic environments
This paper addresses the problem of motion planning (MP) in dynamic environments. It is first argued that dynamic environments impose a real-time constraint upon MP: it has a limited time only to compute a motion, the time available being a function of the dynamicity of the environment. Now, given the intrinsic complexity of MP, …

During the horizontal linear movement of the aerial working platform, the motion of boom is a time-varying system and it is difficult to obtain the solution of Eq. (19) directly. According to the solution approach mentioned in [21], the motion of boom is discretized in the time domain, and the terms related to speed are omitted to obtain the ...
Belt Driven or Lead Screw Driven Linear Actuators? | PBC Linear
A belt-driven actuator converts rotary motion into linear motion using a timing belt. The timing belt contains teeth that lock onto toothed pulleys, applying torque and preventing slippage. Often, the belt drive is enclosed within a protective case, and attached to a carriage. The driveshaft and motor are often situated perpendicular to either ...
