During the summer of 2020 Triple Helix designed and built a testbed for developing software code to accurately aim a turret on a moving robot base. This first generation uses an unpowered base on casters, with a camera and laser pointer on a geared pan/tilt. The goal is to be able to automatically hold the laser spot stationary on a vision target while manually rolling and spinning the mobile base. If successful, this can be the basis for future turret style shooters for Triple Helix to use in competition.
This spring, Triple Helix once again partnered with a Virginia Commonwealth University occupational therapy doctoral student to develop assistive devices for people in the Hampton Roads region. The team created this accessible bow mount for Camp Bruce McCoy, a residential summer camp for adults with a brain injury in Chesapeake, Virginia. This device will enable single-arm operation of a recurve bow which will be mounted in the shooting gallery at the camp. The team provided both right-handed and left-handed versions of the bow mount to the camp.
The bow mount is fabricated from laminated sheets of 1/4″ clear polycarbonate. Triple Helix cuts this material on our 80-watt laser cutter, but these parts can alternatively be fabricated with more common shop tools (e.g. jigsaw, hand drill). The bow mount enables the user to aim the bow in both the azimuth and elevation directions before shooting an arrow. The bow can be installed at any height, enabling archery practice for both standing and seated users.
A generic camera case for a VGA USB Camera Module (640×480). Includes flexible mounting points. Camera can be oriented as desired and includes a connection port on the back with two small slots for a strain-relieving zip-tie. Secure camera board with M1.6 screws.
Arcade pushbuttons normally use standard miniature snap action microswitches to provide momentary input to an electrical device. When latching push-on/push-off switch functionality is desired, use this adapter to install a low-cost latching pushbutton switch in place of the microswitch.

This spring, Triple Helix partnered with an occupational therapy doctoral student from Virginia Commonwealth University to develop assistive devices for people in the Hampton Roads region. Through communication with the Children’s Assistive Technology Service (CATS) a need was identified for a modified ride-on toy car, based on the University of Delaware’s GoBabyGo project. This project aims to provide access to low-cost mobility devices for young children without other means of exploring their environment. In this case, the recipient was a young girl who does not have the ability to move her lower extremities as a result of a birth defect.
To provide access to the car’s controls, a 5-inch switch was mounted on the steering column and wired via a relay switch to the car’s motor to replace the foot pedal function. Additionally, PVC handles were added on each side of the center switch for more ergonomic steering control. To also allow for simultaneous propulsion and steering, the handles fit over a laser-cut Lexan frame which, when flexed, activate an additional limit switch on each side of the steering column. This design concept can be applied to other ride-on cars, depending on a particular child’s needs and functional abilities.
