Helping Kids Run Wild: Sensor and Microcontroller Enabled Ride-On Vehicles
Many children born today with mobility limiting conditions face both developmental and social challenges as a consequence. New technologies offer potential solutions to help overcome these challenges, yet comprehensive adoption is hindered by the cost. Inspired by the GoBabyGo! initiative from of the University of Delaware, this project aims to increase the capabilities of adapted ride-on vehicles using standard robotics and hobbyist RC practices. We have created a sensorized vehicle retrofit with an mbed NXP LPC1768 microcontroller and XBee RF module. This retrofit includes simple actuation using an RC servo motor to achieve drive-by-wire steering control, and an electronic speed controller enabling drive-by-wire throttle control. Currently, the sensor suite and embedded controller are used to warn of potential collisions, and if necessary, autonomously slow and stop the vehicle.

Enabling Use of Touchscreens: A Practical Design Revision for 3D Printed Prosthetics
Due in part to its recent and rapid nature of adoption, the capability to interact with capacitive touch screens is not a common feature for upper limb prosthetics. Inspired by the e-NABLE Community, this project aims to provide a systematic design revision and simple retrofit to existing 3D printed upper-limb prosthetics to allow users to reliably interface touchscreen technology.
