Impact of bicycle tire parameter on the total rolling losses

The cycling industry is influenced by the approval of the tire pressure control system in competitive cycling. This system allows real-time adjustments to the tire-road interaction during races. The total rolling losses is the resistance resulting from tire-road interaction, incorporating resistance due to tire deformation and the dissipation of...

Evaluation of the handling of a variable dynamics tilting tricycle: A novel handling assessment method

The favorite way of transport for commuters is still by cars, which are designed too heavy and too wide for the average amount of passengers. Accidents without other traffic users make up a large proportion of crashes for free-tilting bicycles. Tricycles have a chance of rollover while cornering fast.Therefore, new human-powered commuter...

Design of 3 DoF and 6 DoF Force and Moment Balanced Manipulators Based on the Spatial Pantograph Linkage

Design validation of the MATE tendon-based passive device for post-stroke rehabilitation

Rehabilitation robots have been shown to be effective in post-stroke gait rehabilitation. However, these devices are usually expensive and suffer from high inertia which decreases transparency. The Minimally Actuated Tendon-based exercise Environment (MATE) is a tendon-based rehabilitation device, designed to be cost-effective and minimize...

Multi-axial fatigue assessment of a lemniscate crane

The main purpose of this report is to investigate flaws within Cornelis Tromp 25T lemniscate crane upper arm joint. This is done in order to figure out why the joint structure is experiencing significant crack propagation and what potentially could have led to a structural joint failure and death of an operator within a crane of the same model....

Differences in the mediolateral control of balance during gait between 2D and 3D bodyweight support systems

Training with bodyweight support (BWS) systems can improve the likelihood of regaining normal locomotor abilities for neurologically impaired patients. It is known that people alter their gait parameters when walking with BWS. However, it is unclear whether 2D (vertical and lateral support) and 3D (only vertical support) BWS systems affect these...

Wind load simulations and inertia scaling using an industrial robot arm

Existing wind load simulators such as wind tunnels and fans have multiple disadvantages, especially when used in a scaled-down environment. This paper proposes to simulate wind loads by using an admittance-controlled industrial robot arm rigidly attached to a research object. Admittance control should make it possible to simulate wind loads and...

Safety of Automated Driving in Mixed-Traffic Urban Areas: Considering Vulnerable Road Users and Network Efficiency

The establishment of areas for safe automated driving in mixed-traffic settings is one major barrier in the development and adoption of Autonomous Vehicles (AVs). This work investigates safety in the interactions between AVs, human-driven vehicles, and vulnerable road users such as cyclists and pedestrians in a simulated urban environment in the...

Trajectory control and dynamic modeling of a tailless flapping-wing robot

The DelFly Nimble is a type of tailless flapping-wing micro air vehicles (FWMAVs) that has received an increasing amount of attention. FWMAVs show efficient and agile flight possibilities at small scale. The aerodynamics and dynamics of these flapping vehicles are challenging and not fully understood. In this work, a strategy to implement a 3D...
